rcnut Posted January 5, 2017 Report Share Posted January 5, 2017 are lower parts kits for AR's also fit LR lowers? I ordered a lower parts kit from Cabela's and specified it was for a LR 308 and the part number is the same for an AR lower. did I screw up and should I send it back or will it work?

SNKEBIT Posted January 5, 2017 Report Share Posted January 5, 2017 One I ordered, (can't remember where) said it was for a LR .308 rifle. Everything fit but the spring for the upper rear pin detent was about 3/8" too short. I made a piece in the shop to make up the difference, but still, was not correct. So, maybe I got what I paid for??? Quote Link to comment Share on other sites More sharing options...
survivalshop Posted January 5, 2017 Report Share Posted January 5, 2017 Should of had a different Part # ,only Cabela's knows Cabela's . The Disassembly & Pivot Pins & Bolt Stop are different & some Manufacturers have the Disassembly Pin Detent Spring in the same place as an AR 15 & the difference in size of the Lower Receivers make the normal Detent Spring too short.

392heminut Posted January 8, 2017 Report Share Posted January 8, 2017 Had the same problem with the short detent spring on my Matrix build. A piece of coathanger cut to .700 as a spacer solved the problem. Quote Link to comment Share on other sites More sharing options...
