Can any lower be registered as an SBR? After the stamp and engraving of course. I'm only wondering because I was thinking of doing one on a Plum Crazy Lower in a while. Just didn't know if the lower has to be built from the ground up. Hopefully that makes sense.

Any lower can be used but it would be less-than-wise to use a plastic lower as a sbr lower.

Okay cool. For what reasons would it be un-wise? I guess maybe because parts can't be replaced?? I have one with just a regular 16 in, upper and it performs great. Are there different internal type reasons or something? Not trying to be rude, I just really don't know.

BTW, awesome picture of the U.S.!!!!

I'd trust an aluminum lower to outlast a polymer one, IMO. I can't really knock the polymers (never handled a Plum Crazy, and the CAV15 I had a while back was pretty sturdy), but if I'm gonna drop $200 on a lower, it'll be aluminum for me.

Slapping a $200 stamp on the worst lower you can buy makes no sense at all.

Bingo.

well fk me, now that the other resident know-it-all has spoken, based on his vast and expansive armorer's experience (posts on ARFKKKOM that he drools over/faps to) there pretty much isn't much left to say!

/thread...cause it's over, dudes!

To get to the crux of your question, OP, back when I was selling lots of PC lowers, I did the drilling on a PC lower, registered it as an MG and then Form 5'd it to PC in Havasu for FA testing. They ran thousands of rounds (unsure of the exact number) but when I got it back the whole lower was full of powder residue so it was apparent that they ran, ran, ran and ran it, with and without a suppressor, judging by all the residue in it.

There was no degradation or enlargement of the sear hole. There were no cracks. There was no breakage whatsoever.

They ended up giving it back to me and I ended up selling it for 250 bucks to another C2.

So, before the King of the Trolls "sinks your battleship" with his snide comments, based on nothing, no empirical experience whatsoever, ask the folks who've "done it". If you want to make an SBR on a PC lower, there's not a reason in the world why you can't, and nothing but folks opinion, based on diddly, why you shouldn't....

'A sample of one makes for poor statistics' as they say. Just sayin'.

mine has ran perfectly, not matter which upper, no matter which ammo.

FLAWLESSLY.

for the money, and the weight savings on my SBR, it was a good match.

I love how the biggest assholes on this site (not excluding admin/mods) are the ones hiding behind the highest amount of anonymity. Perhaps our resident trolls would like to bedazzle us with their experiences in manufacturing or as an armorer for Seal Team Six or whatever other qualifications that make their opposable thumbs useful for something besides giving each other "a nice old-fashioned" or hitting their keyboard like someone should have hit their waterhead mothers for getting knocked-up. C'mon, give us your eggspurt opinions. I'm not a big fan of polymer lowers, but I can find no fault, nor create any fault with a PC lower.

...well, add your sampling data to the mix. What you got?

there is none......

time to move on.

You're right, I don't think there is enough data because serious shooters (I don't count myself as one), for the most part, don't use plastic lowers. I personaly would never own one and sure as hell wouldn't sbr cheap polymer. But that's me. YMMV.
