Weaver is one of the oldest scope mount names, and its cross slot rail became a standard way to mount scopes instead of gun specific mounts.
Founded 1930, Oroville, California, Made in USA · Scope rings and bases · Weaver rail · Hunting rifles
W.R. Weaver started making scopes in 1930 and grew into the largest riflescope maker in the world. The company changed hands many times after 1968, and today the mounts are made in Oroville, California, in the old RCBS factory.
The thing Weaver gave everyone is the rail. A Weaver rail has 0.180 inch slots against 0.206 on a Picatinny rail, so Weaver rings and mounts clamp onto a Picatinny rail fine. Its tip-off split ring mount from 1953 became the template other makers copied.
The line today is mostly rings and bases. You get 1 inch, 30mm and 34mm rings, Grand Slam and Quad Lock ring systems, one and two piece bases, AR mounts, shotgun and pistol mounts, and gunsmithing tool kits.
Weaver is the most added optic mount, in about 42% of builds that have one. It's also cheap: about $15 against roughly $65 for the typical mount, which makes it the easy way to hang a scope.
The trade-off runs the other way on rails. Picatinny gear won't always fit a true Weaver rail, and Weaver slot spacing isn't standard. These are simple hunting style rings and bases, so you don't get quick detach levers or the tall cantilever mounts many AR optics want.
We'd buy Weaver rings to put a scope on a budget AR or a hunting rifle. For a red dot or LPVO on a duty rifle, a dedicated one piece mount is the better spend.

Got this weaver optic mount for my ar15 and it's been awesome. Easy to install and holds zero really well. Took it out to the range and put a few hundred rounds through it with no issues. Solid American made quality, would buy again for sure.
The weaver scope mount is just ok. It does the job i guess, but the fit and finish isnt as nice as some other brands ive used. Its been holding zero alright, but not as good as the one i had from another company. overall its an ok product, but probably wouldnt buy it again.
just got this weaver mount the other day. installation was straightforward enough i guess, but the quality feels a bit cheap compared to some other mounts ive used. its holding zero ok, but im not fully convinced itll keep doing that after lots of use. probably a decent budget option, but not sure id call it a 5 star product.
