I've sunk everything possible into the rifle...only stock parts are the RIS rails, bolt handle, and receiver (I even have the PDI one, I'm just too lazy to sand it). I've even replaced the mag catch and all those small internal parts you don't think about
Using .43 madbulls, swapped my inner barrel for promo, and it's shooting with a good amount/consistency of hop with a TM bucking (finally)...that might change, but I'm good for now.
My last question until I get back in the field is:
I bought the parts for a laylax cylinder set separately and assembled/installed them, and my cylinder is still picky about how it catches on the piston sear when I pull it all the way back. There's a technique to it that works, but if it's not pulled straight back strongly, it won't lock in and will retain tension. Is this anything to be concerned about? I've really only noticed this recently because of my weakened condition after surgery.
I'm using a zero trigger, by the way. I replaced the screws, etc. and it's anchored firmly, with the piston sear engaged. There is no wear on any of the parts concerned.
