Also no experience with Colt, but I pulled the supposedly staked nut from my Bushmaster with just one of those cheap $5 wrenches (because Bushmaster had a 3-month backorder on the big solid multi-tool wrenches). Wasn't "easy", but I got it done with a fairly normal amount of blood, sweat, and tears (and plenty of words not fit for a 9-year-old's ears).

I LOVE my ASP plate and Magpul MS2 sling ... most versatile sling I've found.
