    Posted by on 26th Apr 2019

    I run a company ,Otter Ordnance ,we specialize in the SPR ,Recce type upper reciever groups,let me tell you guys,this barrel is what we use ,it is accurate ,well made ,and i would compare this barrel to other high end spr barrels on the market .we will only barrel our upper receivers with Green Mountain barrels, period .

  2. Excellent Barrel 5 Star Review

    Posted by on 21st Nov 2018

    I've been using this barrel on my 3-gun rifle for the past couple years and it has been great. It shoots 2/3rd MOA with a high powered scope, which is better than I can shoot with my 1-4x Meopta. It is a very good profile for those looking for something heavier than Govt profile, but don't want a bull barrel.

  3. Oustanding fit, finish, function, and accuracy 5 Star Review

    Posted by on 14th Sep 2017

    Arrived well packaged and in perfect condition, installed easily and without any issues at all to a Noveske upper, and with perfect function and, as far as I am able to assess with a CQB optic and mid-range factory ammunition, great precision potential. Can't wait to upgrade the glass and see what it is capable of at long range.u

  4. Does not get any better! 5 Star Review

    Posted by on 30th Apr 2017

    I ran 100 rounds of 55 grain American Eagle. I took it home ran some Hoppes no 9 threw it with a brass brush and a few patches. Took it out a couple days later with a beat up box of Winchester 69 grain Match ammo that they loaded with Match Kings that i found on the clearance rack. I do not reload. And this was my first AR build. I shot consistent sub moa groups smallest being .25 at 100 yards. Like i said doesn't get any better.

  5. Great for an SPR style build. 5 Star Review

    Posted by on 23rd Jan 2017

    I am a type 7 mfg and there is only one grip I can see with this barrel. The barrel info is marked right in front of the barrel extension, so once the upper is built you can't see it. For most it will only be a cosmetic issue.

    As far a performance goes they seem awesome. I was quite surprised when they were stacking 55gr American Eagle ammo @ 50 yards during function testing. It will be nice to see what they will do once broken it and fed some good ammo.
