building an AR9

[kbstenberg]

I have been looking at Bear Creak Arsonal / PSA / 22mod 4all.
I would prefer PSA but BCA and 22 Mods are both available now. The BCA just went from out of stock to instock.
Any information on past experiance requested

I’ve been thinking about getting some cmmg rotary bolt parts for a .45 build but have enough projects going on now. Maybe later this year. I’ve built 3 .45acp pcc’s using Olympic Arms bbls/bolts, dpms uppers and dedicated gg mag lowers. They turned out great but do get dirty. Good luck on your build.

I've got one SS AR-Stoner barrel which are made by Bear Creek when Midway had them on sale for $60 a few years back. As it came the feed ramp was pretty small and it didn't feed well. Opened up the feed ramp to copy a Sten MKII that I put on the 9mm barrels I've made and it feeds fine now. The bolts I have are PSA or Spinta. They both work, they're all the older pistol extractor style and not the newer M16 type extractors. The main issue is feeding. You'll have an easier time getting it to feed well by going with a dedicated lower than with one that uses a magwell adaptor. Centerfire had dedicated CMMG 9mm lowers a couple years ago cheap so I got a couple and haven't regretted it.
