Howdy,
Recently finished my second lower build (first ending up as an A2 clone) and topped it off with an EXT carbine length upper in 300 Blackout... happy with it, came together nicely and shoots quite well... My question is in regards to the rails; was looking to add a couple to the sides, perhaps one for the bottom, but Anderson seems to have these perpetually on back order... does anyone know if the screw spacing (for lack of a better term) is proprietary or is it possible to pick up another manufacturers rails? Mounting holes are 2 5/16" center, apart. Thanks in advance for your help. |
