The SPR grip is very nice but I ended up swapping it out for the ERGO Delux due entirly to thr SPR grip preventing weak side use.
I know some of the 308's use a differnt grip but I cant say for sure ifDPMS is one of them. Just keep the right hand only issue in mind before comiting to a grip.
Thanks for the info Anchor Station, I have the Ergo on my Ar-15 but the grip is a bit small for me. No worries about the weak side as this will be a steel buster/paper puncher along with some deer hunting.
I dont care for the ergo at all untill I saw the tactical delux (yeah dumb name). Its big and fat and puts your finger in the right spot.
Having said that you dont mind if its ambi or not you wont be dissapointed with the SPR its a great grip for correcting some of the ergonomic shortfalls of the AR.
