BARSKA M-4 Handguard Rail Mount (Short)

Just installed this rail on the lower handguard on a Colt 6920 M4 Sporter Carbine with the double heat shields. When I first approached the project, it appeared that the double heat shields were going to be a problem since they are apoxied in place. Also, there are no instructions included to help with installation. But, after looking it over, I could see that the heat shields can remain in place and the flat nuts provided could be slipped in between the heat shields and pushed to their location with a flat tool. After pushing as far as possible with the flat tool, leverage them into their location at the other end. There is some minor resistance. Make sure the flat side of the nut is facing to the inside of the handguard. I then slipped folded pieces of paper in between the heat shields in such a way as to press and hold the nuts against the body of the handguard.

I purchased this rail to convert my Kel-Tec SU16C from its plastic rail to an Aluminum rail. The original rail could not be zeroed with out shiming the rings to one side.

This rail has worked out perfect for my needs.

Fit perfectly on my M-4 hand guard, even has the correct taper to line up with the barrel which is important for mounting lasers. Nice sturdy build and mounts securely. Glad I tried this as it has room for a weapon light and bi-pod or grip and has holes that line up with the handguards vent holes.
