Fixes issues with the gl-mag - FAB Defense GL CORE MAG CP - M4 Survival Buttstock w/ Built-in Mag Carrier

This stock fixes the rattle issue that the GL-MAG had with mil-spec buffer tubes while also cutting down on the bulk. It comes with 2 sets of inserts (one set for mil-spec and one for commercial) to make sure it has a tight, no-rattle fit. The back also allows for a good support hand grip when the rifle is braced against a barrier. The base stock with no magazine weighs exactly the same amount as a Magpul MOE SL stock. This stock did reduce my length of pull by about half an inch so if your build is close to being an SBR be careful.
