US Reaper and Reaper with OTB Eval Q&A

[wind gypsy]

Just got in a reaper from their raffle. Trying out a slightly different configuration.

Ive got the SRS brake and the titanium area 419 hellfire system adapter on the reaper.

10.5 oz.

Compared to a tbac 9.

Well, how's she do with the brake?

Im trying to piece together an upper for an aero precision ar10. I really like the features of the reaper or ab raptor 8/10, OG-L etc. But for any of the OTB type suppressors, like the reaper with the reflex, how much barrel do I need from the gas block for it to fit. I know I can put a smaller or larger gas block on, but most all are a standard length, but I dont want to get the suppressor then get it home and find out I have bought the wrong length barrel lol Im thinking by looking at different barrels I will need at minimum a 18" or 20" barrel for the reflex part of the can to fit over the barrel, and use a rifle length gas system, not hit the gas block and still be able to tighten it down. Am I thinking wrong? Thanks for the help.
