CMMG Front Sight Base Assembly F

Came exactly as pictured and advertised, a flat top height undrilled front sight base.Used a Brd Engineering jig, #31 drill, and 2/0 reamer to install it onto a virgin 20" gov't profile barrel I'm building into an a4 clone. It looks like it was factory installed on the barrel and matches black parkerizing. Easier to install undrilled bases this way than trying to align existing holes. If your looking to just tap existing holes to do a set screw install instead, there are more pre-drilled bases available on the market than undrilled like this one.

The product is fits perfectly on barrel not loosen or slack but no screw or thread inside the front sight where hole to hold the barrel that why gives 4 stars if it has bolt and thread then 5 stars .

Unable to mount, no holes or set screws, no pins, no way to even use. Junk

Complete assembly with post. These DO NOT come drilled or with taper pins as they have to be drilled and fitted to each barrel individually. Machining or gunsmithing required. I drill, tap and set screw these to barrels after dimpling and they work great.

Completely incomplete. No hardware of any kind. Not even milled for pins or set screws. Too bad you can't give 0 star rating.

Looks good and fits right

Had to return since it was not drilled for pinning to the barrel.
