9mm ar questions

[Daleo8803]

Ok guys I have some questions.

I'm looking at using spikes Glock lower. It says it has a last round hold open. Can I just use a normal upper receiver or does it also have to have the last round hold?

With it being a blow back can I use a standard carbine spring and a heavy buffer( 7 or 8 oz) that is made for it aka extended. Like the kay valley precision 7.5oz.

Would the Kay valley precision BCG be a good one? Recommendations?

Can I use the heavy buffer with the shockwave brace set? That comes with the brace, tube, and spring? Thanks

Yes, yes, I'd get a CMMG or Faxon, yes.

But to elaborate, get a BCG with the removable weight and then get you a JP Silent Capture setup. You'll be in love. A bit more money, but a great investment.

Dale I am in rock hill and have a couple of PCC's I have the JP spring , a Taccom recoil kit , and a heavy buffer setup with a 308 carbine spring you are welcome to come and try each in yours to see what works best before you buy .

What I know about 9mm ARs is they won't kill things as good as 45acp ARs.
