Good economical handguard - Magpul Industries MOE SL Mid-Length AR-15/M4 M-LOK Handguard

I bought this handguard for a 7.62X39 upper. Since I didn't need or want a freefloat, and planned on installing a front sight, this fit the bill. Installation was a little fiddly, as it's a snug fit between the barrel nut and the handguard cap, but it's solid once on. I added a QD swivel to the M-Lok slots, and that seems solid, too. The metal liner does a decent job of shielding your hand from barrel heat. If you're looking for a non-free-float M-Lok handguard, this one is worth looking at.
