Carry handle scope mount is brand new. Fits in the carry handle very well, only problem is when you put the scope on it, the scope is in a front downward 20 to 30 degree tilt, not good.
I have a Bushmaster, Mod m4a1, cal .223 per sales paperwork, but on the side of the magazine well it says .223-5.56MM, MOD XM15-E2S. My upper does not look like the E2S in Bushmasters booklet that came with the rifle in a hard case, reason is there is no rear site adjustment wheel at the base of the carry handle below the rear peep site. SOOOO, I guess I just found out I've been ripped off. Never the less it is a great rifle and I need to find a scope base mount that will fit this rifle.

If you don't have a flat top upper you need this to mount any kind of optic. Just add a dab of locktight and your ready to rock and roll. The price can't be beat and it will work for most any shooting need.

I got one of these before I even received my A2 upper just because of the price! I have to admit, the nut does come loose, but a little thread lock put a stop to that!

inexpensive addition to your rifle and its sturdy. good buy ,im happy

If you are using a low power optic or a red dot these work great, the mount is vary solid and with low rings you get a decent cheek weld
