I've tried other manufacture rails for the buckmark and while they are good the main complaint is that the screws back out rather easily. This OEM mount for the buckmark still allows one to use the lock washers and with a little loctite have held rather nicely. The reddot that I am using seems to mount better with the weaver rail and if using such an optic a great upgrade from the original plastic part. The only down side is the lack of an adjustable iron site.
Pros: Price, quality, OEM
Cons: No Backup iron sights
