Upper question...
Posted: Fri Jul 10, 2020 7:04 pm
I received my bbl, gas block, gas tube & bolt tonight. I had a upper and ol free float tube forend. Its lil heavy. But works for now.
I Got nut torqued & aligned.
I installed tube and set loc ring with tool I made to align pic rail.
I dis and cleaned then re assembled bolt/BCG. only a quick problem with FP retainer. I polished the top and it went right in!!
I do not have proper mags. But should be ok for couple rounds loaded in mags.
Durn thread @ muzzle is bastard thread. It appears 5/8x32. I hate comps and flash hiders. That concussive blast kills it gor me. ( Getting blown up in another life, does that yo ya..)
Any how here is my question....
Upper ejection port size... mine is just over .500.... seems small. Do I need a specific upper for this 450?????
