I'm happy with it. Rock solid tight fit, lightweight ( aluminum ).
Laser is about 2.55" below bore center.
Momentary switch on TLR is perfectly accessible with left hand forefinger... with, or without bulky gloves on.
I considered cutting the sling slots off, but decided to keep them.
Installation requires drilling the existing sling rivet head, and removing the sling swivel.
Tap the mount in place with a mallet ( it's a tight fit ), then installing two hex screws ( one on side, and the one on bottom that contacts the lug ).
I got the last one from Midway - ok to back order ... Cheap / Dirt is sold out / no back order.
UPDATE: Back in stock 23 bucks -
