Thinking of ditching the AR for something piston ran. Considered the piston conversion by Osprey but then ill have some good money into this in trying to "improve" it.
Sig 556?
SCAR is too much money.
Convert the AR to piston?
Go with an original piston design gun?
Screw it all and get an AK?
yep... brake cleaner makes it super easyI take my upper off, yank the bcg and CH, spray some non chlorinated brake cleaner in there then blow it out with compressed air, spray lube, reassemble, done.
AK or FAL, perhaps? Both are reliable - battle-proven all over the world.
