Matrix Mk46 5-Position Retractable Stock for M249 / Mk46 / Mk43 Series Airsoft Machine Guns

"The default stock on the m249 is large, and clunky, and has low play ability. This stock can fulfill the stock size of the default stock AND is collapsible for a much easier time lugging it around and such. Parred up with a 45degree offset mount vertical grip, it’s much easier to aim.
It was a pain in the @$$ to put on. Regardless, a worthy purchase if you don’t want the para collapsing stock that only has two settings.

"no complaints, Drop in fit on an Echo-1 MKII

Well. Weights about half a pound more, but due to the potmetal cast buffertube on it.... However a nicer stock for adjustable LOP. is more then worth it.

"I love this stock! Much more comfortable than my old para stock. It is crazy the difference it made! Also looks pretty awesome!

"Great stock, much more comfortable than the Para stock I had on my M249 (now Mk46).

However, it is wobbly, thanks to the taper they put in the buffer tube hole. Likely from the injection molding process. Not sure why they did this, as M4 stocks don't run into this problem.

-1 star for the wobble.

"It’s a really cool and comfortable stock but the only thing is that it doesn’t fit right away on the Cybergun featherweight version of the m249 I had to sand down a bit on the pink holes and it doesn’t come with pins if your wondering and the top pin hole doesn’t Aline properly either so u have to make the hole bigger on the actual gun.It will also hit hold a battery

"Overall it really completes the look for my 249 but sadly the stock has a wobble to it and on the CA M249 it doesn't quite fit the original set screw for the top of the stock not a big deal though all you have to do is file down the support holes to make them slightly wider.

"DO NOT BUY THIS STOCK!!!! When I took it out of the box, the inside of the bag was covered with black paint flakes from where it was coming off the entire thing. I took it out, shook it and it was snowing black pieces of paint flakes on the floor. Its like somebody took paint thinner to it. Wait and buy the others stocks
