The grip panels and slate stop are top notch. They look great, feel great, and give excellent control over the front of the rifle. I do have one complaint and that is that the M-Lok screws are too long. I am running this on an FM-15 with the thin handguard and the screws are so long they press against the gas block when installed. They also prevent removing the handguard over the muzzle device because they stick out about twice as far as they need to. Nothing a Dremel tool won't solve but that would be the only improvement I can think of for an otherwise great product.
