Matrix 7" Free Float Full Metal Rail Interface System for M4 / M16 Series Airsoft AEG
by Chris A. Date Added: April 15, 2009
This is an excellent RIS system. I would put this against the UTG replacement RIS hand guard any day of the week. I put this on my KWA KM4A1 and it fit beautifully, after some careful strategy about where the wires should sit. Placed a Matrix vertical grip and Matrix PEQ2 box on the rails and not only did it all fit brilliantly, the free floating feature is extremely durable. No flex, no droop, no wiggle, no noises, just pure perfection. If you have an M4 with the standard delta ring configuration and standard ABS handguards and you need/want an RIS configuration, this is an excellent choice.
