The Matrix Weaver to Weaver (W2W) rail interface adapters are a great way to mount small launchers, shotguns, and other small arms & accessories to a long-gun rail system. Initially designed as an answer to mounting small 40mm grenade pistols to rifle rail systems we quickly found that the Matrix W2W mounts are a great accessory to keep in your gear bag for a multitude of purposes. They make it possible to mount all types of railed accessories to another rail interface.


  • Adapts one rail interface to another to make a solid mounting point
  • Universal for all Weaver and Picatinny accessory rails
  • Great for mounting underslung launchers, shotguns with top rail, small accessories with rail interfaces
  • Made from durable aluminum, finished with a corrosion-resistant coating
  • Set of 2 adapters
Application: Connects one rail interface to another
Compatibility: All Weaver and Picatinny rail interfaces
Material: Aluminum

"Best item to grab if you plan on doing some fairly mad experiments. I used epoxy to fix some rails on a shotgun then attached it to a Combat Machine to make a budget (functional) masterkey. These will hold whatever you put them on tightly and securely no problem. The only issue I have encountered is that the bolt head stripped and now I can't detach the shotgun (not that i would want to anyway), but retaining that option is always nice. If I knew the bolt size, I would put it here. If anyone does, pls put it in the Q&A section or in their review.
Overall, these WORK and work well. Just the bolts are prone to stripping.

"works great i mounted the pocket monster to one of my m4s and it looked great and was on there tight. only thing is getting on there is annoying but for thrwprice not bad if there where a little longer that would be super.

"THIS IS ONE OF THE BEST THINGS TO BUY EVER!!!!!!!!! you can use this to attach a tri shot shotgun to your m4 for a masterkey like I did. yes, yes you can and even with the $20 m47 sawed off shotgun by double eagle with the 50 round mag(for you kids out there with spring m4, ak or other guns with rails). you can even put a gbb MP7 or any other gun on your full metal aeg or gbb rifle if both have rails. I experimented with these and DUDE!!!!!! JUST DO IT!!!!! AND BUY THIS!!!!!!!
