Faxon Match 7.5 Gunner 300 blackout 1:5 twist
I have purchased several Faxon barrels and researched the 1:3 and 1:5 twist barrels. When I saw this 1:5 in 300 blackout, I jumped on it. Shot it this morning and was very happy with this purchase. Outstanding barrel. Its my favorite and love it. Kudos to Faxon.

A real winner
While I may have some complaints with the 10.5, this barrel is a real treat. It likely outshoots my skill, and the craftsmanship is absolutely spot-on. Not sure if anyone else produces the 1:5, but this is where it's at for subsonic shooting! Haven't really tested accuracy (or gassiness) for supers, but I can't think of a better value product for shooting subsonic! Likely irrelevant for most users, but the Nickel Teflon extension is slightly over-spec, and mating this to an under-spec'd BCM upper had me sweating bullets that something was going to break...

Spot on
Perfect length IMO. I have this barrel running on my SBR, I'm using standard buffer and an adj gas block. Shoots perfect, suppressed and not supressed. This is my backpack SBR and I couldn't be hoppier. I'm on 4 Faxon barrels and will not buy anything else.

7.5" 1/5 twist 300 blk barrel
Love the barrel, running 100% supressed with an SLR Sentry adjustable gas block. Getting 1" groups @ 25yrds standing with Winchester 200gr HP subs. Running a Spike's Tactical lightweight bcg with Spike's T3 buffer and chrome silicone buffer spring.

So far so good.
Just finished upper less than 100rds through barrel at this point, accuracy is better than my capabilities at this time. Shoots 110 and 155 loads with equal accuracy, 220s as well just have not tested accuracy with the 220s. Very happy with this barrel and hoping the 1/5 is of some benefit to bullet expansion, time will tell. As stated barrel is very accurate with multiple bullets weights, does well with suppressor, fit and finish are excellent and price is very reasonable.

Fits my needs for a build in progress, availability & pricing were both positive factors.
Purchased to upgrade a build I had built earlier. Wanted to try a different set up. Looking very much to get it out on the range & do some comparisons.
