OK, give me the dirt on the LWRC product. Specifically the M6A2 SPR model. I am not hashing out the DI vs Piston issue, just wish to know if anyone has seen any verifiable problems with the product. I sent a few PM messages to some of the AR informed here on GT (some answered, some did not ... "thank you" again to those who did). Wanna kill these ads? We can help!
