What do you think about bolt lugs? I saw few .223 ar15s with broken lugs. Are those bolts also expendable parts with ready to use replacement at hand? What use should I expect before worrying about replacing the bolt?
Sorry for lame and perhaps off-topic question about conversion cone and bull barrel comp - together with the barrel itself they make 3 peace "thing" - bushing barrel->conversion cone->comp. What about durability of this setup? Have anybody had any issues with it?
