Greg,
Sir, you've been helping me stay alive for almost 6 years.
I know it's been a long time since you've heard from me. I ordered your Viper when I was in Haiti and brought it to Iraq.
My M16 Viper has saved my life more than 30 times and I know it works.
Can you make me another Viper upper, the same as the one you made me six years ago?
I want another one for stateside work and my house. I'll be sending it to my Class-3 guy to fit it to my lower receiver.
If you give me current prices, I'll order another Viper upper.
Again, thanks for making such a great lifesaver.
I would really be honored to meet you the next time I'm in the US. Take care.

G:
Man, the M16 Viper-XRP is one nice shooting upper! I am still in awe at how it hit at 300 yards.
I made it through CSAT's Tactical Rifle Instructor Course! Six, 12 hour days, 1,500 rounds, and sunburn.
The Viper-XRP made it through without a problem.
Our quals had us shooting from the 100, 75, 50, 25, and the 7 yard lines. The Viper-XRP shot and grouped very well.
It really impressed me on the 'Scrambler' part of CSAT's course; where my Viper scored solid hits at 300 yards, 200 yards,
100 yards, and on steel. I got first round hits at 200 to 300 yards!
I was putting 5 hits on a IPSC target at all ranges. All out of a 10" barrel.
Paul Howe was impressed that I completed the course with the Viper. It was the shortest AR platform he ever had complete the course.
He knew the Viper was capable of doing it, but the short sight radius made it a hand full at longer ranges (zero room for mistakes).
Paul had trained guys with the Viper before, but none had tried the Tactical Rifle Instructor course.
He has heard lots of good things about your ability to take problematic ARs and turn them in to 100% reliable guns.
He said that the uppers you build are 'Shooters'.
Everyone noticed the lack of muzzle jump when I fired the 5/1 failure drills.
I shot three other ARs while there. The Viper had less muzzle jump, and less recoil than any of them.
At no time did I find it heavy. It is better balanced than most M4s.
I am very happy with it's performance. My classmates were impressed with it.
I saw almost every brand of AR/M4/CAR made and saw several failures.
I saw a Colt bolt break, a Wilson M4 clone fall apart, a Bushmaster lose a gas key bolt, and a VLTOR chamber start sticking.
I never had so much as a hic-up from the Viper.
Here are pix of the Viper-XRP atop my lower receiver, and of Paul Howe and myself.
thanks,
TE

The bores in the Lothar Walther barrels are the best I've ever seen in terms of concentricity.
There was no perceptible runout on any of them.
The proprietary stainless was extremely tough, but clean cutting.
These are some extraordinarily high quality barrels!
(and a tribute to M16 Clinic for having the skill and determination to deliver the best of the best.
Be well Greg, and congratulations on your clearly successful transition up in Utah. Teaching your Wizardry of the M16 will help Cops win gunfights!
All my best,

Greg,
Just wanted to let you know that I got the M16 Viper upper and it is everything I expected and more.
When i showed my buddies the Viper put onto my weapon, they all wanted to know where i got it; they wanted one as well.
So you will probably be getting a few more orders from my AO in the very near future.
Your product is excellent, as is the service. That is the message I will convey to anyone interested in a high quality AR15/M16 upper.
Thank you again and I look forward to ordering my second upper soon.
Best wishes!! Stay Safe!!
MIKE

BAGHDAD
Greg,
Well you truly make an exceptional upper for my weapon; not that you needed to hear that from me.
Opponents to the short barrel rifle have spouted off at the decreased range of my weapon until they actually fire it.
It is perfect for my job as a PSD shooter inside of an armored vehicle. It is easy to swing and quick to acquire targets.
I have not had any of the typical failures short barreled rifles are rumored to have.
Nor has it ever “short stroked” a round. Every round fired the weapon has performed flawlessly.
Thanks for the Viper!

Greg,
THE VIPER-XRP PERFORMED SMOOTHLY AND RELIABLY. IT'S BULL BARREL IS LARGER THAN ANYTHING I'VE SEEN.
OTHERS HAVE SAID THE SAME AS THEY LOOKED AT IT IN AWE.
THE XRP IS WELL BALANCED AND BARELY BUMPS AGAINST YOUR SHOULDER. I HAVE ONLY GOOD FEELINGS ABOUT IT.
THE COSMETICS/SMITHING IS CLEAN AND IT LOOKS SHARP. THE XRP NOT ONLY LOOKS THE PART BUT IT HANDLES THE PART.
USING 69 GRAIN PMC SIERRA MATCH KING AMMO; I GOT 0.75" GROUPS (5 SHOT) AT 100 YARDS.
JOB WELL DONE.
THANKS,

Greg at M16 CLINIC:
We just got our Viper (8") and dropped it on one of our M4 Lowers; man what a difference.
We took it out to a local US Army Installation and proceeded to zero it in. We zeroed the Viper on M4 zero targets at 25 meters.
Once it was zeroed, for fun we put it on a shooting bench and strapped it down.
Then took it out to 50m, 100m, 150m, 200m, 250m and finally 300m.
At 300 meters the Viper shot multiple 6 inch, 3-round groups !!!
We couldn't get that out of our regular issued M4's, the M16 Viper is a screamer.
No tactical team should be without one. If your team is converting from a pistol to rifle round, the M16 Viper is the way to go.
Our Viper is 1/2" shorter than our fellow agencies’ MP5's !
Since the bench testing, we've used it on a few call outs and it's perfect for all Law Enforcement work.
Every Agent, Officer and every Agency I meet, I'm recommending the Viper. M16 Clinic's Viper is one hell of a Force Multiplier.
Greg: Keep up the great work. More purchase orders coming your way.

The M16 Viper upper I purchased for use on a stag lower is great! As my first class 3 firearm it is impressive.
I did my research and could've chosen other options. I am glad I bought the Viper.
I heard of the tight groupings produced by your M16 Viper; was waiting to see what it could do!
I shot a couple strings and was impressed.
These strings were shot kneeling and standing at approx. 50yds practicing quick reaction drills. Tight!!!!
Thanks for an awesome product.

Hey BRO.....finally a decent pic!

Been training with the guys at the combat outpost; nothing but RESPECT for your products!!!
The M16 Viper is sweet as butter: NO misfires, NO jams, and it throws the brass forward instead of back like all the regular M4s.
Also nice to pull the pins and pack it in my carry-on pelican case when flying in-country.
Thanks again for a great product and for all of your help.

Greg,
Amazing results out of my 762x39 Viper!!!!!!
I am very excited about getting out on the road with it.
There is nothing like the ability to throw some lead at the enemy, using a QUALITY weapon that is totally reliable.
Working with 10th Group and they are fresh for the fight. They relieved 20th Group.
Take care and I'll talk with you soon.

Greg,
When I first heard of your weapons, I was intrigued. I sat down with you and discussed my specifications and needs.
You customized the M16 Viper to the point I trust my weapon exclusively and will not use any other AR or M16.
Without question, the M16 Viper performs flawlessly.
My weapon commands accurate, sustained fire. Your creation exceeds my expectations.
Obviously so. My team mates have purchased the same model.
The M16 Viper is a fantastic weapon, built with perfection, attention, and fulfillment of customers' needs.
Ordinary M16s and AR-15s cannot deliver.
I could not be happier!

Hi Greg,
I finally got to shoot my new M16 VIPER with some of my fellow operators. It functioned flawlessly and everyone was impressed.
Here is a good K-9 with Viper photo for you, I did not forget. Thanks again, I am thrilled with the performance of the Viper.

Greg:
Your 762x39 M16 Viper upper and this lower made the most perfect match of an AR that I have ever seen.
This is the tightest fit. Absolutely no light between the upper and lower receivers.
Without a doubt the perfect firearm.
With this said, if you would be so kind, please work me up a price for the 16" that we discussed.
See you next week, and thank you for all you have done.
Best Regards,
Dave R.

M16 Cinic:
Our M16 Viper functioned flawlessly all day.
The instructors had a drill at 50 yds........five rounds in unlimited time, into a 5" circle.
The VIPER was first to complete two strings,(approx. 6-7 secs each string).....and the BEST group.
Class members were very impressed!
thnkz for a great product!

Hi Greg:
Just got the viper today, and let me say that this thing is slick!
The quality and finish are great and it fits perfectly, with a whole lot less play in it than my M4.
My M16 Viper is tighter than my m4 upper, from the charging handle to the play between recievers,
and even the amount of wiggle room (or the Viper's lack thereof!)of the bolt carrier.
No problems getting my peq-2 and Surefire to mount up either.
My platoon Sgt. really likes it and will be in contact with you. I'll send pictures soon.

I seasoned up the Sniper Viper and proceeded to bench test indoors, at twenty five yards.........
Seven rounds in a group half the size of a dime. BEST group I ever shot!
The Sniper Viper could not get any better.....Simply the best.
Thanks Much !!!!

Greg:
I just got back in country and what would be waiting for me at my room?....that's right!
My 5.56 Viper was there all ready to be matched up with a colt full auto lower.
I don't think I have to tell you what a great job you did.
I can't wait to get my 7.62X39 Viper.
I've been telling everyone about the 8" M16 Viper chambered in 762mm by 39mm,
and they all cannot wait to see it.
I explained to them ahead of time that it will be nothing short of sensational.
Hope all is going well for you and I appreciate the great service.

Professor:
Here is our M16 Viper getting ready for action on the streets of Ogden, Utah.
The Viper is ideal for the tactical operations we conduct and is utilized in all aspects of the job.
Because of its size, it is easily deployed from a vehicle and in the small and confined residences where we
serve warrants and conduct other tactical operations.
The M16 Viper is ideal as a patrol rifle
and is highly recommended to law enforcement officers working urban arenas.
Thanks for your commitment to quality and excellence!!
Thanks again for your friendship and all you do for all of us out here who are trying to make a difference.

Greg:
Just checking in and letting you know my Viper XRP is still rolling along like a Swiss watch.
"VIPER Envy" story, last summer: a foreign Head of State flew in, along with his attendant security people
and our Secret Service crew. I usually get assigned to the Secret Service just because I have been in the past.
So there I was again, when the Dignitary’s plane touched down, chatting with the Secret Service boys.
We got ready to escort the VIP, so I uncased my M16 Viper. Well, when we were done escorting the foreign dignitary,
the Secret Service all had to see my M16 Viper, hold it, and shoulder it!
They were impressed!
They all had MP-5's but liked the size and increased fire power of the M16 Viper over their pistol caliber weapons.
Thanks again,
GEO

You caught the quality control issue in the cross hairs and your take is straight on the mark.
The quality of manufacturing varies from manufacturer to manufacturer.
You and I have discovered and discussed the pitfalls of certain products and companies.
The same holds true for builders and tuners of M16's.
A few years ago, we sought out an M16 expert, and found the best. That expert, my friend, is you.
Enough said....

Greg,
Thank you for the box of goodies and the spring, I really appreciate it.
I test fired my M16 Viper this morning and it didn't miss a beat. I had a guy
from from Blackwater next to me.
When I put the VIPER onto 3 round burst, he
nearly jumped out of his skin. I love the noise it makes.
Again, thank you Greg, the M16 VIPER is amazing.

Greg,
It's been a long time in coming but I'm finally putting pen to thank you again for my Viper.
I've had a role shift and am now enjoying the capabilities of the Viper.
Both its accuracy and performance cannot be faulted. A firearm I carry without reservation.
The firearm itself has created a cult following among the team and is sought
after every time I go on leave. You'll be getting a new customer by the name
of Dan B who is a new member of my team and wants one of his own.
Once again Greg thank you for the efforts and expertise you put into your
products. I hope 2006 is a prosperous one for you.
Regards'

The M16
VIPER is absolutely “The Weapon” for PSC (Private

Its
compact size, superb accuracy and total reliability make
it invaluable for Motorcade/EP Ops.
Greg at the M16 CLINC is an absolute genius when it comes to the M16.
Thanks
for the GREAT product.

Greg,
I would like to take a moment from this crazy place I seemed to have made my permanent home for the past two years and thank you very much
for the coins and muzzle covers.
It means a lot to receive even the smallest of gifts from those back home. I gave two of the coins and kept one for myself.
The Desert Tan muzzle caps were not only very operationally welcome; but, as usual, the guys found a way to play with them and stuck them all over their faces.
The other two individuals S and T are thankful for your remembering them while they are serving their duties here.
I've had problems with Bushmasters. I suppose the result of mass production and less than perfect craftsmanship.
We all can't thank you enough for the outstanding weapons that you have put together for us.
My M16 VIPER is the envy of several individuals because it looks and feels so great.
It is a comforting feeling being able to hit the road knowing that the weapon (your M16 VIPER) I hold is going to save me as far as my skill level will provide.
Thanks again, Greg
Hope to do more business with you. Take care and god bless.

Dear Greg,
I just wanted to express my utmost thanks to you.
I deal with many tactical companies and the customer
service I received from M16 Clinic is outstanding.
My M-4
has had over 20 magazines through it on both auto and
single and has not missed a beat since receiving your
equipment. My weapon receives a lot attention from
other PSD teams and US Forces here in Iraq, with the
inevitable questions about reliability. I always
tell people: “If you've got a question about M16s, then
speak to Greg at the M16 Clinic; as "He’s the Man!"
All the
very best for the future.
