I have at least two rifles set up with Hiperfires and Radian Talons. They work fine together. YMMV.

If you don’t, and have the charge handle on the left, you WILL lose some hide. I cut the top off mine and left it on. I can use the charge handle to release the bolt. Probably should remove it but I thought I’d try this first.

A lot of people run coated bullets in subsonic .300 BO, so I doubt they clog the gas system too quickly. And I’ve never had any trouble running some pretty blunt shapes in my .458 Socom. You’ll just have to give it a try!

.45 ACP won’t run in a standard lower, which I think is what the OP is looking for. And .458 isn’t a straight wall cartridge, also required. Although I agree, for other things it is far preferable to the .450.

I experimented with various different springs and had to go back to stock for reliability. Seems like a new trigger is pretty much it, although I got considerable improvement by polishing.

Thanks everyone, somehow I never saw all the advice. I got a bit more interested in it and ended up getting a Prusa Mk3 kit. Very nice, no tweaking needed yet, and fun to assemble too. More $$ than I originally intended but no regrets.

My guns run stock STI mags without tuning. I’ve been just getting the tubes from Brownells on one of their promo deals and adding Grams guts and base pads. Pretty cheap.

I like that. I could turn my Eagle into a legal SS .40. I wonder if it would make weight. Probably would.

I’ve tried a few different styles. My current favorite is VZ Diamondbacks. More aggressive than most. I like them rough.

I have a CMR-206 on mine. I use it mostly as a hand stop for the SBR and don’t turn it on, but my son used it once when the Holosun sight was too dim to see. The auto brightness setting doesn’t work when shooting from a dark house into sunlight. He just hit the laser and kept shooting.

I rather like this.

My son has decided he wants a 3D printer for his model airplane hobby. I am thinking magazine extensions, tool holders, etc., so I’m agreeable. I know little about this sort of thing but am trying to learn. Here’s what I think I want, tell me what you think. I think I’d like the ability to print ABS. This seems to work best with an enclosed printer with a heated bed. I’d like to be able to print things 7.5”-8” long. Hoping to find something of reasonable quality in the $400-$500 price range. The printer of interest at the moment is the XYZprinting daVinci 1.0A

Me too, please!

I see...I prefer your previous design.

Is this your second upper then?
