Chicken, I'd prefer to buy one to have, but I may take you up on the offer. I just dropped my Ram off at Huffines, can you bring it with you tomorrow? I'll PM you my cell #.
Pig, look at the bottom on the one you posted and it says... "Does Not Fit: DPMS LR-308 (Use Product #294971)" and the the 294971 they reference says "This wrench will not remove DPMS Delta ring barrel nuts." The confusing part as I read both descriptions, it doesn't sound like it would work for either model?
OK, yours looks the same as the one I have.
