[ARCHIVED THREAD] - POF upper fitting all lowers?

Posted: 1/28/2006 9:38:06 AM EDT

looking at the P-415-16-BP-SF 16" GAS PISTON UPPER W/PLASTIC HANDGUARDS.

Recently started back to AR platforms with Armalite M15 and now with Colt LEO 6920 and Colt LEO 6520 on its way.

One POF upper ($$$ consideration) to interchange with all lowers to start. Will it work?

TIA

My POF upper fits my CMMG lower perfectly and that is the only lower I run it on.

My POF upper has been on a Rock River and Doublestar lower. Both fit fine. Like I referred to in your IM, Colt has SOME lowers (not sure which model #'s) that utilize non-standard takedown pins. I believe your 6920 should work though.

Take the "Piston Plunge". You won't regret it.

Newer Clots have larger/non-standard pins. Older ones like the SP1 have smaller/standard pins but the screw and large diameter pivot pin hole...

This is good news to hear because I have a Double Star lower that is just waiting for it's recently ordered POF upper to come in and make it complete! From what I hear, the wait will be a while.
