The bolt I got from Alyosha weighs 340.2 grams. :)

I printed the lower in PA6-CF, guess I’ll have to give it a shot (pun intended). Probably will end up Form-1’d with a 10.5” upper in .300 BLK. Thanks for the tips, I’ll see how she shoots :)

I guess I'm missing something in the build; I printed the PRS style stock, but how does the buffer get held into it? I don't see a set screw point for capturing the buffer and spring inside the stock assembly.

BiPoly Question (forum.guncadindex.com)

Howdy all,

Quick question on the BiPoly, as I've only built 80% AR builds up to this point. It doesn't appear it takes a standard buffer tube; is there a way to run a traditional stock on the BiPoly setup, or does it have to be one of the printed stocks that come with the file pack? Obviously it's not threaded for a buffer tube, but it would be great to be able to run a standard multi position AR stock on it; I haven't been super happy with the printable 3 position.

Thanks

FTN.4 Size? (forum.guncadindex.com)

Seems like the FTN.4 .223 Can is HUGE compared to my .223 factory cans. I know there are obviously differences in material used (Metal vs polymers), but are there any good .223 Cans that are similar in size to a 'real' .223 can?
