Good evening.
Before I begin, the full rifle setup is a aero M5 upper/Lower, rifle buffer tube, Geissele SSA-E, Failzero Bolt carrier and rubber city armory high pressure bolt carrier firing pin/bolt, criterion 18 inch 6.5 Creedmoor barrel, superlative arms gas block, and a Rearden flash hider.
I am having a issue with my bolt not traveling far enough rearward to pick up a round off of the magazine or lock the bolt (not while firing, just while working the charging handle). Prior to installing a Geissele and also trying a springco rifle length spring, and using the noveske rifle length buffer I was able to have perfectly fine bolt lock/loading with my JP AR10 SCS with the rifle spacer installed behind the spring. I was trying to replace it because I was told by criterion to try and go with a regular rifle spring and buffer to solve some premature pressure signs before sending a barrel in. I have a AR10 rifle length buffer on the rifle and the bolt is a failzero body with Rubber City Armory high pressure bolt, have not had any problems prior to this. the buffer fits perfectly with the AR10 magpul gen 2 PRS stock and fits the rifle spring fine. Are Noveske rifle buffers longer for some kind of special noveske buffer tube? scratching my head here as to what is going on.
When I take the Geissele/springco and noveske buffer combo out and put the JP back in the rifle functions fine, but I want to try the regular buffer spring/buffer combo to see if I can possibly alleviate early pressure signs (rifle even shows ejector swipe pressure signs with factory hornady ammo).
