I'm sure others sell the same mount. This one is sold by Galati

I have a few questions:

1.) How would you rate the mount overall for quality/usefulness
2.) How long is the rail portion of it? I'm wondering if there's room for a BUIS behind it.
3.) How much does it hang forward? In other words, how much offset does it offer.

I'm curious about this mount because my scope needs a bit more eye relief than standard rings/mounts provide.

looks similar to the armalite mount if not removed a lot it will work fine as a mount but wether if it works for you i have no idea

adcofirearms offers it for cheaper and is also a site supporting dealer.
