Most Helpful Positive Review Faxon 7.5" 300 Blackout

I always recommend Faxon barrels for 300 blk mainly because the gas port is a perfect diameter. As far as the shipping, Im furious it came losely packed inside of a thin shipping bag with zero bubble wrap, it is a 7.5" barrel that was put in a 20" x 20" plastic bag so i'm 100% sure its been dropped ...

Great Barrel

Faxon barrel works great for a nice compact build. The 1-5 twist makes for a very accurate shot.

twist does amazing things

Had a 1:8 twist on my 300 blackout tuned for subs. Put this on, groupings and overall ballistics showed noticeable improvement. Don’t use cheap ammo, it will rip it apart

great barrel. instal will be tricky

by Jon, Verified Owner from MN, United States Written on June 23, 2026

So it’s so short that a normal gas block overhangs the threads. I used a sig M400 gas block and it leaves about 2mm between that and the back of my suppressor. Also to get it to cycle subs with a traditional can I needed a springco yellow and KAK aluminum weights

Now it works great!

Pros:

None

Cons:

gas port diameter too small for subs

by Booker, Verified Owner from WI, United States Written on June 14, 2026

Other than the title it's a great barrel. Had to drill to .110. Smooth sailing now.
