Matrix 3/6rd Burst-Shot Full Metal M870 Airsoft Gas Powered Shotgun by Golden Eagle
(Model: S-XI / Black)

"These are solid shotguns for cqb. I have the S-III and the S-XI. I love the look of the XI but the mobility and practicality of the III is really hard to beat. The XI leaked slightly from the box but this fixed itself after a couple fills of green gas/silicone mix. The capacity of the XI is much better, but if you are getting the S-III you’re probably going to, and you should HPA Tap it.

Accuracy is about what you’d expect. Anything within 100 feet or so is fair game. The action is smooth and fun to use, you can slam fire if you’re in a pinch where you need to put a lot of BBs down range fast. The matrix m4 adapter fits great, and you don’t need to remove the feed tray door to fit it, though it does look cleaner if you do. The XI came with the pictured handstop, shell caddy, and 6 shells to fill the whole caddy. The S-III came with the pictured grip and 3 shells. Fitting Mlok attachments on the pump is possible, but there is not a lot of room for the screws and locking lugs, and removing the pump requires complete disassembly of the gun to my knowledge, at least with the S-XI. As for shells, the ones it comes with work the best. The red/black matrix ones seem to fit a little too tight.

All in all a great gas shotgun that does what it was designed to do very well.

"Got the S-II, first one that came in the gas tank wasn't sealed properly so had to return. The replacement I got fixed the leak, but it didn't feed until after I dry fired it a few times. Now it runs fine, and I was able to convert it to HPA using the Russian CQB adapter for the Jag Scattergun. A note on that is the handle for the S-II doesn't let the HPA adapter screw in all the way, so I sealed it with teflon tape, and it seems to hold up so far.
