For the price these are really nice freefloat handguards that have enough inside diameter to accommodate a can. I have one on a 300BLK upper and love it—nice machining, easy mounting, lots of attachment points. The only annoying thing is you have to buy the (proprietary) barrel nut separately, for 20 bucks or so, to mount it on a standard upper receiver. Sometimes you can find a third-party vendor deal that includes the barrel nut in the price. If you like a thinner handguard with a built-in top rail, their ATLAS series rails are worth a look.
True. I'll add that 300 Blackout is much better shooting with a supressor as it can me loaded to be subsonic, unlike the 5.56.
I like this pistol format and built one. I reload, so don't get impacted quite as hard by the more spendy ammo.
