I'm thinking about building a 458 SOCOM upper.
I really want a muzzle thread that will allow be to use my TiRant 45 silencer (with subsonic loads only of course). I think 5/8-24 is probably my only option which leaves with with Tromix or SBR barrels (Wilson uses 11/16-24 and RRA uses 5/8-32). Tromix uses a pretty non-standard .875 dia at the gas block which limits my choices of an adjustable block (I want a restriction type not bleed type like Superlative Arms)--I'll probably end up going with the SBR Cromoly despite my preference for stainless to get that muzzle thread and a standard .936" dia at the gas port.
Is it best to buy a 458 upper receiver or should I enlarge the port myself (or have it done)? If so, which brand? Which brand of bolt?
Any things to look out for that may be different than my 5.56,Wylde,300BLK, and 9mm builds so far? Feed ramp modifications/blending, etc?
Thanks, Mike
