Matrix Full Metal Scope Mount Base for M14 Series Airsoft AEG Rifles

"For $16 i cant complain. Very secure and absolutely no wobble what so ever on my echo1 m14. However it sits kinda high above the bolt which is both a pro and con. Pro cause you can still use your irons. Con cause my cheek isn't in contact with the stock when im aiming down a scope or really anything i have on the mount. This could just be me cause i have no meat on my face just skin and bones. You can easily fix this my making or buy a cheek riser. Otherwise a very good scope mount. n.

"It works, but was a pain to install and adjust.
2 issues:

-First, the small block that mounts in front of the rear iron sight needs to be centered for the scope rail to be straight in line with your barrel. If you just slied it in all the way to the stop, it's likely not going to be straight. In my CYMA M-14, this required a few times guessing and readjusting.

-Second, the large thumb screws are very soft aluminum, and the threads did not match up with my gun. So the front one needed to be replaced with a steel allen bolt from the hardware store. And the rear fits in the supplied block, but seems to be stripping out as I tighten it. Likely will replace it with another steel bolt.

But, it's on now and scope is sighted in fine.
I do like how it has a channel underneath that lets you look down the irons for backup sight.

"I got this tactical rail for my Cyam M14 and It fit the platform perfectly, but the only complaint that I have is that there is no guide or piece of paper that shows you how to install the piece. The screws that go into the sides have a tight fit and have a tendency to strip when you screw them in, one of my screws completely stripped and wouldn't go into the port and so I had to make my own screw to hold the rail in place.
