Is the the set screw on the front of the "free float" to hold the cover ring in or to center the handgaurds on the barrel? I am a noob at pistol length any thing and heard that free float makes a world of dif. With ar's for accuracy! Help please.... looking for a 300 bo upper for my to be built lower pistol in 300.

All I have left is the hand guard, barrel nut,barrel, gas tube, gas block, and flash hider...$160 503 960 6965 I used the rest of the parts for a new AR15 Build

when you ran the upper previously assembled, did the gas system function reliably?

Not as reliably as 223. I like 300 blackout but there isnt enough factory ammo..most my rounds were hand loads from cut 223 brass. I dont have the patience to dial in a 300 blackout setup/reloading... I can do barrel, gas block, gas tube, flash hider for $120 the handguard and upper is already on another AR...im keeing the dies and when powder becomes more available I will play with 300AAC
