Magpul UBR stock with 20" CMMG MedCon

[GTXR390]

Hello Chris,

Was referred here by ElectricFan...also read some of your posts. anyway, my question is:

Planning on building a 20" upper...looking at the CMMG MedCon, with DD rail, M16 bolt carrier, and maybe LMT enhanced bolt and carrier....I'd like to use the UBR stock for this setup. Would i have to buy an A2 spring and buffer?

I've read, the UBR comes with its own buffer? still a rookie, just need to know what parts will mix and match and make my rifle run in harmony!

Thanks,
GT
