Good budget drop-in hand guard - Strike Industries Carbine Length M-LOK Handguard

This hand guard may not be as refined as the MOE or MOE SL from Magpul, but it is high quality non the less.

The grip is aggressive in texture and allows for a good purchase when pulling a rifle tight into the shoulder. The front of the guard doesn't extend passed the front sling loop, so there is no need for it's removal from the barrel for installation. The front of the guard also has a stop built into it, which is great for barriers, or, in my case, as a place to put a finger around to pull a rifle firm into the shoulder.

At a price of sub 30$ you cant really go wrong with this hand guard.
