AR-15 22lr Build

AR/M4 Custom Build Forum

Hello everyone. I’m knew to this ar-15 building but have purchased a lower & going to slowly put it together while adding tools to do so. I have one question on building a 22lr version.

If I buy a dedicated 22lr upper, then I get the 22lr BCG. Correct?

If I use an ar-15 standard upper (5.56/223) then I need the 22lr conversion BCG. Right?

Any places I can get a the BCG & upper other then CMMG, Taccom, CORE-15?

There’s a certain handguard I want so don’t want to buy the full upper.

Thanks in advance.

Thanks for the links although it didn’t really answer my question. Reference vacation, if their were no views I wouldn’t had said anything.

Valid. My apologies.

The BCG is almost identical. The only difference is the 22LR conversion BCG has a chamber insert for a 5.56mm chamber, and the 22LR dedicated BCG has a collar in place of the chamber insert that interfaces with the .22LR barrel extension. You can easily change out a chamber insert for a collar, or vice versa.

I think CMMG is your best bet here for 22lr parts. The 22lr BCG conversion w/ 1mag is $180 shipped at Aimsurplus

I think PSA also puts those magazines with stainless lips on sale quite often… maybe $12?

I haven’t shot a lot through mine but also have had no issues
