Kenter Posted February 9, 2013 Report Share Posted February 9, 2013 Hello all I've recently purchased a DPMS LR308 SASS made back in 06. I've noticed the upper moves from side to side as well as up and down on the rear takedown pin. Has anyone else experienced this? I bought a gapper for it like on my AR15. But there is no way it will fit in there. Also the bolt doesn't lock open after the last round? Any and all input is greatly appreciated and welcomed!

Robocop1051 Posted February 9, 2013 Report Share Posted February 9, 2013 Welcome Kenter!It sounds like you have two unrelated issues going on. Before I get into those, isn't the "Gapper" that little thing you stuff behind the trigger guard? That's just a comfort thing. It won't tighten up you rifle any. For the wobble in your receiver, that was normal in the older models. The specs were more like guidelines then. You can try an Accu-Wedge or replace the take down pin with a tension pin found here Quote Link to comment Share on other sites More sharing options...

Kenter Posted February 9, 2013 Author Report Share Posted February 9, 2013 Thanks fellas for the warm welcome!Sorry Robocop I said gapper and meant Accu wedge. There is like no room for it in there. I was thinking why the bolt won't stay open. Is because out has a rifle buffer in it. It has the original Magpul PRS stock Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted February 9, 2013 Report Share Posted February 9, 2013 Try boiling the accu-wedge in water, dry it off, then install it while it is hot. It should crush easier and then form to the shape needed (like a football mouth-piece). You also may have to shave a bit off the bottom with a razor. The accu-wedge can be a "shape-to-fit" accessory, especially in regards to the 308AR.The Magpul PRS uses a rifle length buffer system. When the bolt doesn't lock after the last round, it is usually a gas issue, and not a buffer issue. Although it wouldn't hurt any to upgrade to a heavy buffer eventually. Check out the gas system again. Make sure there are no loose screws or leaks. Also check receiver resistance. Remember that the 308AR likes to be VERY wet as it breaks in. It could take 100-200 rounds before the parts really start mating to each other. You can polish the inside of the upper receiver and the BCG a bit too. Don't forget a little lube on the buffer as well.... I'm not kidding about the wet receiver part... DROWNING!!! Quote Link to comment Share on other sites More sharing options...
Kenter Posted February 11, 2013 Author Report Share Posted February 11, 2013 Hmm... Well I'll have to do some closet gun smithing. I'm also looking to shed some weight. It seems all the weight is coming from the barrel nut at the rear of the hand guard. Is there any way to slim the girl up? Quote Link to comment Share on other sites More sharing options...
