It does not fit Magpul PRS GEN 3. 18/03/2018

Screw hole it too small to use ported screw supplied Magpul to attach stock.

Definitely recommended

Hard to pass up when it was on sale! 28/12/2017

Well it looks like your standard run of the mill AR rifle tube. The package said it was a tougher grade of aluminium and I have zero reason to not trust that. Finish is a tad better than what it replaced, I CAN say that. I used this on carbine stock swap out for a rifle length ACE/Doublestar ARFX SKELETON STOCK on my PA-10. "Heavy duty" made sense since .308 and this tube is largely protected only by a bit of foam on this stock. Got it on sale made it just a no brainer.
