-Covers part of the lip.
-piece o' cake to strap on.
-Little heavier than the stock grip.
Okay starting from the top:
Easy, whip off the original grip, push the bolt to the end and slap on the foregrip, then just whack the screw in.
###ERGONOMICS### (<---or some funky word describing how it works :P)
If ou try holding it like a rifle you may find that your palm doesn't actually fully touch the grip (-0.2), which is annoyingly because of the cyclone feed. I have a few ways of holding it, one of which I just throw my fingers over the cyclone itself so it's like holding a swolen rifle. Otherwise, it really helps with getting down low it, you can buy versions with a space for a gas thru mag (i didn't) It's also very sleek, infact I reckon it's most streamline than the original. So if you find you have to throw one of two A5s at someone, one has the stock grip and one has this grip. Go for this one.
I'd buy this, I did, i'm happy with it. If you are a dagger player and want to get down low, here it is. I give it a 9.8 out of 10. which rounds up to ten =D
