DPMS PSG-1 Style AR-15 Pistol Grip

I have one on an AR-15 and one on an LSS chassis equipped Mossberg MVP. I really like the grip even if there are a couple sub-optimal factors. It provides a place to rest your hand so you don’t have to maintain a positive grip to keep your finger in position to activate the trigger. This leaves your hand without so much fatigue. The shelf lends itself well to sitting on top of a sand bag. I like the rear bag under the grip instead of under the butt-stock. Under the butt I have to tuck my off-hand arm under my upper chest which leaves my back and shoulder aching after a long day behind the scope. With it under the grip my body position is lower and my arm is out front instead of under me. The ergonomics just seem better that way. I use these on .223’s that I like to shoot squirrels with. Since I’m liable to spend from sun up to sun down behind the scope comfort is a big factor.

The beavertail doesn’t fit every AR-15 nor does it fit the LSS chassis. This is a thing you get used to with AR platform guns. As interchangeable as the parts nominally are, there are fitment limitations and exclusions here and there. Removing the beavertail is fairly simple with a dremel tool and cutoff wheel. After chopping it off there’ll be a small gap at the top of the grip where it interfaces with the frame of the rifle that needs filled with epoxy to smooth everything out. Once the epoxy is set and cured then you can polish up everything and contour it with the dremel and a few bits of sandpaper in varying grits.

Among the design elements that I just can’t bring myself to think are good is the idea of a single retention screw fixing the palm shelf to the pistol grip. If they’d have used two cross bolts then you’d be able to reliably fix it in position. With just the one you have to snug the shit out of it to keep it from moving under vigorous action and it doesn’t really fix it totally in place. I’ve hit the ground with the rifle a couple times doing shoot-n-move training and the shelf has shifted position severely. It’s nothing a little epoxy won’t solve but I was hoping to not have to use epoxy.

When installing it make sure to remove the shelf and the cross-bolt and sleeve retaining it or you won’t be able to get the grip screw to thread cleanly and may gall the snot out the threads on your rifle.

Fit of the grip was 4 out of 5 stars. It fits easily rather than snugly. I’d honestly prefer a little more snug fit for this part.

At about $20-30 it’s not a bad bargain. I never intended on using it as delivered and modified them before even mounting them to a weapon. They lent themselves well to being modified and the materials and design are sufficient for civilian use cases. If you want something combat worthy, keep looking.
