Good budget handguard - Presma AR-15 Super Light M-LOK Series Free Float Handguards

For the price it’s a decent handguard. Very light and a nice finish. My build took a bit of fitting to get the barrel nut screw holes lined up properly, but that seems to vary from barrel to barrel. The only thing I wish it had was anti-rotation tabs to lock into the upper receiver, but would likely be difficult to do while keeping the price low.

The included m-lok rails and hardware was an added bonus, but they are polymer so I wouldn’t recommend for anything that puts force on the rail like a bipod or foregrip, just a weapon light or something like that.
