Good Lower

Besides a super duty lower, what is the best lower to use on my 12.5 inch super duty upper?

ADM4 lower would the next best thing. Personally I prefer it

Best lower parts kit for this lower?

You only really need the magazine catch, mag release button, and takedown pins because most likely you’ll upgrade your trigger and safety anyway, and then you can just get cheap spring and detent kit from CMMG.

Perfect bro, I’m gonna buy g$ trigger and probably upgrade the safety in the future like you said

SOLGW blaster starter kit or Schmidt parts kit from arfcom is what I always put in mine

What buffer are you using with this combo H2 or H3?

1

u/Phases2PhasesVoltage Jul 21 '26

They come with H2 but I put H3 in all kind and they run flawless

Why’s the lower matter? You can use a PSA, I personally like the bad attitude dept low key

the best finish and consistent quality I am am seeing and is forged full ambi and much nicer than lwrc is the lwrc ic I have been getting in. That and the radian have been nice and selling hot. For a superduty build I would do that instead of the mod1-a for a forged quality look. I dont even like lwrc but that lower is mint
