MGRIP AIR EXTENDED | M-LOK ANGLED FOREGRIP
$25
Foregrips in both major rail standards. M-LOK bolts straight into the slot for a slim, lightweight profile with no adapter to buy. Picatinny clamps across a MIL-STD-1913 rail for maximum compatibility with most builds. Start with whichever rail is already on your rifle, then pick the shape and length that suits how you hold it.
