FAXON PINNED GAS BLOCK GUNNER PROFILE 16" MID-LENGTH 5.56 NATO AR15 BARREL
Faxon Pinned Gas Block — 16" Gunner Profile 5.56 NATO AR-15 Barrel (Mid-Length Gas)
Lightweight Gunner contour with a factory pre-pinned .625" gas block for rock-solid reliability.
The Faxon 16" 5.56 Gunner Barrel with Pinned Gas Block eliminates the hassle of pinning your gas block. Faxon pre-notches the journal, pre-drills the low-profile gas block, and includes the retaining pin—ensuring your gas system won’t loosen or shift under recoil.
The Gunner profile blends the durability of the Gov’t contour with the weight savings of the Pencil profile for perfect balance and fast handling. Constructed from 4150 CMV steel with a QPQ nitride finish inside & out, it’s button-rifled 1:8 twist for excellent all-around accuracy and longevity.

Awesome barrel
Great barrel! Love the stress relief. No extreme spread at 100yrds when the barrel is smoking hot. Maintains same POI. Great finish, great quality, great machining, and love the 1:8 twist.

Gunner Barrel
Happy so far. Light weight and looks great. Few hundred rounds though it and everything seems good.

Good choice for a light weight build.
Light and balances well. The pin adds a measure of confidence to the two set screws.

700yd With 55gr Ball
I, an utter novice in assembling AR-15s, was able to achieve a 700yd shot cold, never having shot a 5.56 rifle to that range before. To eliminate the possibility that those hits were a fluke, four of my friends took the same shot and were able to make it with the same ease. The quality of this piece was exactly as promised, though the larger-than-standard gas port has proven to be slightly frustrating. All-in-all, 100% recommended, though I'd say one ought to go with the non-pinned version and buy an adjustable gas block to go with this.

Straight shooter
The pre cut notch for the gas block ensures it won't go anywhere and it makes the Installation easier. It balances perfect on my KP 15 and would recommend it to anyone that would like to make a WWSD type rifle.

Barrel for First Build
I bought this barrel for my first rifle build and it is exactly as described. It feels light on the build by keeping the weight closer to the middle of the gun. Fit like a glove on my Aero Precision Upper. I haven't done anything crazy with it yet but it seems very accurate sighted at 25 yards, pushed to 100 with a red dot. Shipping and packaging were all good. I will definitely shop Faxon for my next build.
