I put the RR National Match in it when I bought it to lighten the lead weight it came with. I just dropped a chip mccormick trigger in one of my 556 AR's for a match last weekend and loved it, light and crisp. Has anyone found a solid single stage trigger for the LR308 or can I use the 556 chip mccormick in my 308? My RR Arms trigger was for a 556 and it has worked flawlessly. Thanks for the help.
