If you want a pic rail for accessories, this is it. - Leapers MP G36 Handguard Picatinny/Weaver Full Size Rails MNT-G3603

3 Rails for the price, how can you beat it?

Not used on a G36, but as an accessory rail on a Bolt action. Comes with mounting hardware, (hex screws) but you probably will have to get your own hardware for anything else than use on a G36.

Holds my predator light in place, is true picatinny sized slots. Aluminum can be cut / shaped to your needs. If only needing a few slots here and there, you end up with twice or three times as many mounting points with cutting and drilling your own holes.

sling studs (threaded type with nut) will also fit in / through the holes, though you may have to shim the stud higher with a washer or two for clearance depending on how you are installing.

flat bottoms, no tapering, not as sharp ended as other rails though the use of a rail cover is always suggested to protect the rail, your skin, and your equipment from snagging.

Bottom line it's hard to beat for the price, if you need rails, these are worth it.
