AR15 x39 question

[84wh1]

Good morning,

Im doing a 10.5" 7.62x39 AR build. What weight of buffer should I use for x39? Also any recommendations on bolts? Ive already got a colt carrier.

Cheers

I run a standard weight buffer in mine with a psa upper and bolt/bolt carrier group. It works flawlessly with every type of ammo I've fed it.

excellent thank you. Any extraction issues running steel cased corrosive?

There is always a chance with steel cased ammo the longer you shoot. Just drop a couple of drops of oil in the barrel extension area behind the locking lugs. Also replacing extractor spring and o-ring helps if you having extraction issues.

Make sure there is no oil in the chamber or barrel, that could lead to excess pressures. and don't mix steel cased with brass in the same shooting session. If it starts short-stroking keep BCG wet.

I haven't had an issue with any steel cased surplus ive used. Chinese, russian, Romanian, tula, Czech, branaul and dominion arms lcw or whatever it was called. I run the bolt wet and have fired upto 300 rounds in a session without any hiccups. Use a good clp or whatever lube you choose and you should be good.
