great tool, must have for any upper work.
got mine while they were in stock, get them while you can!
fits solid in the upper, very little play when working on your upper.
After reading many threads on building an AR w/ a Larue rail, I was told that these bad boys were the best to get! No drilling involved to make it work like the action block and it will do what the action blocks will do. Yes it cost 10-15 dollars more than the regular blocks, this product pays for itself in labor, sanity and time!
This is a must have if you are purchasing the VLTOR M.U.R. The VLTOR M.U.R. wont fit in any of the other blocks for various reasons, 1 being the difference of design of the Forward Assist Assembly. The Claw is a quality piece and a must have if you are replacing a barrel or barrel nut due to over indexing
Works great, used it only twice so far, but will be using it again tomorrow, so far has made barrel removal and installation a breeze, worth the money!!
