FAXON PINNED GAS BLOCK SOCOM PROFILE 16" MID-LENGTH 5.56 NATO AR15 BARREL
Faxon Pinned Gas Block — 16" SOCOM Profile 5.56 NATO AR-15 Barrel (Mid-Length Gas)
Duty-tough SOCOM contour with a factory pre-pinned .750" gas block for rock-solid reliability.
The Faxon 16" 5.56 SOCOM Barrel with Pinned Gas Block removes the most tedious step of an upper build. We pre-notch the journal, pre-drill the included low-profile gas block, and supply the retaining pin—so your gas system stays locked in place under hard use.
Built from 4150 CMV steel, button-rifled with a 1:8 twist, and finished in black nitride inside & out, this SOCOM profile offers excellent heat control and longevity. Every barrel is stress relieved, air-gauge tested, MPI-inspected, and headspace verified in-house for dependable accuracy.

Proven to get the job done
I owna few of these Barrels, and I'll probably buy even more in the future. This SOCOMProfile gets the job done with reliable and consistent performance. Depending on Ammunition, you can expect MOA performance/accuracy. Ordering it paired with the gasblock prevents me from "Forgetting" something during the ordering process (Though, I still forgot to order a Gas tube this last time). I have barrels with over 10k rounds through them, and some with less than 100 rounds. The barrels with over 10k do show signs of wear, but it is expected when you use it primarily ona demo gun that sees lots of Mag Dumps using some junk ammo at times. The Finish holds up to abuse well, and the feed ramps have lined up very well with the Upper Receivers I have used (Aero,Palmetto,Faxon, Rainier, and many others). I think most users will be very satisfied with this barrel setup. I gave it 4 Stars because the barrel is a bit on the heavy side, and finding ammunition to get sub MOA performance has been difficult. I'd prefer to give it 4.5 stars
