Guys, Thanks for the help!
The rail came in Saturday, but with everything going on w/ Christmas, I didn't get a chance to install till yesterday. I'm now the proud owner of two strap wrenches! I think that may turn out to be the best $15 I ever spent! Everything went together nicely. I used a J&T armorers wrench to install the barrel nut. I was worried about it holding up because it only has two prongs to fit the nut, but it did great. Used the strap wrench to tighten the collar to the rail; it didn't mar the finish one bit. All I could think of to align the rail to the receiver was a strait edge. I think I got it really close; just wish I had something to tell me it is 100%. The front sight/block looks plumb; I guess I could shoot it w/ irons to be sure, but I don’t think I’ll ever need the irons.
Thanks!
