I posted a wanted to buy ad but thought I would mention it here too. It looks like they discontinued it and I can't find one anywhere. I need to pull the barrel and work on the barrel extension because its gouging the case neck really bad.
Hmm. I have a couple of DD tools. The RIS wrench, and then something used on the M4 12.0." I dont work with the lite rail. Any chance these could be similar? Can you find a pic to post?
