Fit and finish - Presma AR .308 DPMS M-LOK Slim Free Float Handguards

Received product quickly. No damage to box. Upon inspection found a few slight blemishes in the finish. Shiny spots along the sides. Tried installing on my aero m5 upper and it would not butt up to the receiver. This handguard has 2 ears on it to prevent it from rotating after install. They were slightly out of spec for the M5 upper. After a couple minutes with a file it fits very snug. I'm sure it won't move. All in all very nice for the money, especially if you're not obsessed with the finish. Or planing to repaint it.
