I ordered this product for my ar10, and I like these one piece bases, theyre usually more sturdy than two peice. That this mount is. Only qualm I have with it is the actual mounting part of the base. There are 3 crossbolts, 2 of which are flattened to ride flush against the base/top of picatinny rail! There being only 1 crossbolt to keep this thing from shifting back and forth has me skeptical whether this is going to hold a good zero or not. Product would have been so much more solid had they not flattened the other two crossbolts.
Pros: cheap, gets the job done
Cons: cheap, corners were cut in manufacturing
