I recently put together a system using Faxon components. It’s an AR15 which consisted of their 16” pencil barrel, their new flash hider/ compensator, the Holding Upper and lower, a Faxon bolt carrier assy and a Hyperfire trigger.
I took it to the range today and shot 5 rounds through it to get it close, I was using a Nikon 3-12x42 power scope shooting at 100yards. I put up a target and took my first shot. Made a quick windage and elevation adjustment then fired 4 consecutive rounds. I had 2 bullseyes and 2 just off dead center. The grouping was 0.950”, the ammo was cheap 30 cent a round Winchester 5.556/.223 ammo in the white box from Field and Stream. I was just laying the gun on my range bag

Imagine what a good shooter, using match ammo and on sand bags could do. I bet you would 1/2MOA

Thanks Faxon!

Great for most users needs. Awesome fit and finish and noticeably lighter than a medium contour. Bore came free of defects with no need to polish the feed ramps since they (and the whole barrel) are nitride-ed and smooth with little signs of tooling marks. Slid snugly into mil spec upper with CLP. Cycles flawlessly with PSA bcg- even without lube. Put 3 rounds into the same hole at 25yd sight in (using free float rail). Standard A2 flash hider fit fine and both ends came with plastic protection caps. DD low profile clamp gas block fit snug. Recommend this barrel. (Posted on 8/12/2016)
