Matrix Retractable Spare Magazine Stock for for M4/M16 Series Airsoft AEG Rifles
(Color: Black)

"This stock is very comfortable and materials are sturdy and of good quality. Color matches any other black polymer out on the market and has a flat raised area on top for a sling. However it does have quite a bit of play on the buffer tube. The wobble/play doesn’t affect gameplay though. The other thing that really needs an upgrade is the pin that holds on the adjustment tab and spring-it just falls out. To remedy this I had to put in a cotter pin, fold the excess over and trim length.
Pros: good material quality, aestheticly pleasing, good color, mag storage
Cons: excessive wobble on buffer tube, adjustment tab pin not secure

"Not too bad rather sturdy except for the two flaws I had with mine that I was able to fix.

First is the roll pin for the length adjustment lever was super loose and fell out (had to fix it in the field)

Second the magazine catch on the stock does not have enough positive hold on the mag in my opinion I attempted to do the quick and dirty method of just stretching the spring for more pressure, which didn't work so I just replaced it with a full metal magazine catch I had laying around which made it so much better.

"Just got this stock and it's not bad but it needs a couple things which I'll list here.

1. the pin where the spring and adjustment lever is wants to fall out really easily ( Patched my up with some e-tape and that fixed it.

2. It'd reverse the way the mag release is because other wise you can't hit it your thumb easily like bolt catch you have to reach around with your hand to release the mag which is just inefficient. (I might use a ambi mag release and see what that does.)

3. The back panel is a tad bit of a pain if you want to open it quickly. Bonus points though for it being hinged.

4. A couple small things that are good though. Sling loop on top, easy adjustment. and decent sized pad for shoulder without being to big while using a plate carrier.

All in all I got what I payed for at 22 bucks. If the issues were fixed it happily pay 30 bucks.
