This tool makes it easy to line up your buffer tube straight when you tighten the castle nut. Of course it's on sale NOW! Good stuff, get one!

Great price- especially with no taxes added on to listed price and no shipping charges. Unfortunately item did not fit as advertised on product.

Received the wrong item however they responded that day and had the replacement shipped out the next day and in my hands 2 days later overall pleased with my purchase.

Received scope in timely manner

slow shipping ..... but all good
