The stock seems a little heavier (empty magazine). Had to be man-handled to install and once on is very stiff to slide.

It was disappointing that this stock is not much more stable than the old - has some play fore and aft pivoting around the release... but I will say it doesn't rattle like the standard unit, so in that I am happy.

And once adjusted I don't usually collapse the thing, anyway, so I can live with it.



The weapons are (top) wife's Bushmaster, pretty much stock (light) with Primary Arms 3X compact scope, Elzetta light mount with Surefire G2X. Weighs in at 8 lb 3 7/8 oz. empty.

The subject weapon is my Smith MP15 with the new stock, Primary Arms 3x compact scope, M500A with a TX-4 Cree LED upgrade, trigger work by Bill Springfield. 9 lb 3 7/8 oz empty weight.

I didn't weigh the stock by itself. Mako cites it at 12.5 ounces. References here cite the standard M4 stock at 14.3 ounces. A surprise; it seemed heavier.



Shot with a loaded 10 rnd and a loaded 20 rnd magazine in the stock. No issues.

Predictably, a 30 rnd magazine gets awkward and tail heavy.

I will probably keep the 10 in it loaded with some DRT TerminalShock rounds (if they ever become available again).



Over all a pricey mod, but one which fits the weapon well enough and does give that extra 10 (or 20) rounds "in the back pocket". I've installed one. Pics show (if I'm posting them correctly) the 10 rnd magazine, a 20 and a 30 just for reference.The stock seems a little heavier (empty magazine).
