I put the JP SCS in my wife's sbr. That being said, I have a 8.6oz buffer from a JR carbine "upgrade kit" I need to try out Id love to put a JP SCS in this one but im not gona buy the spring and a new bolt for it. I talked to clint from heavy buffers yesterday and he recommended the 12 oz...

If you did a 9mm sbr build you would probably want a dedicated lower. But they are a lot of fun. I have a few SBRs, and thought I would only build one. One is a 12" Grendel, believe it or not its a awesome round for short barrel. Most think as I did before that the grendel is only for long bar...

Ok gents, what 9mm buffer are you using? Im using a 9mm 5.6 oz buffer but its slinging my brass a good distance and at 5 Oclock with subs and suppers suppressed. Im thinking and looking at the 9mm Q buffer from heavy buffers.com. Whats the skinny on them?

All great points gents! And all great things to think about and consider when building one. Iv put together to many regular AR 15 to count, but when messing with the 9mm AR there are things that arnt like a regular AR when it comes to assembling. I went with a Runner Runner guns billet 9mm lower, a ...

Thanks! No iv got a dedicated 9mm lower also. What bolt are you using in it? I was wanting to use the new frontier armory bolt carrier.

You guys that have used a side charger upper what are you using as vice blocks to clamp the upper to install the barrel? 2nd post on page 3 is a matrix upper. I used a piece of carpet and a vice to put the barrel on. I saw you used one, just wondered how you installed the barrel. I have upper vice ...
