I highly recommend this barrel. Great barrel for SBR or pistol build (I am using it for home defense). I bought the BKF gas block and had BKF pin the gas block to the barrel. The crane spec .070 gas port works great with M855 62 Gr green tip ammo using an H3 buffer and a standard carbine buffer spring unsuppressed and suppressed. I also shot some Hornady Black 5.56 NATO 75 gr Interlock Home Defense (HD) SBR ammo (this ammo is what I plan on primarily using) and it cycled great as well as it was perfectly gassed using a standard weight carbine buffer and spring (ejecting at 3 o’clock) with a suppressor, and slightly under gassed without suppressor but cycled with no issues (remember, this ammo is meant to have less pressure). The groupings were also good for the ammo I was shooting (I did not shoot any match grade ammo) with slightly higher than MOA groups at 25 yards (.5 to .75 inch groups). I am sure it would be much better with match grade ammo and a bench rest or a better shooter than me (lol). Again, I highly recommend this barrel.
