Can an aimpoint sight be installed on an S and W 686?

I am on the verge of acquiring an older Smith and Wesson 686.
Serial number BPK9302.
I plan to use this revolver in Bullseye competition.

I have an Aimpoint Micro H-2 2MOA that I'd like to install on this revolver, if I end up owning it. By drilling and taping some holes, a rail could be installed.

However, is it possible to use the two existing holes and attached a device that will accommodate the installation of the Aimpoint?

I know this an obscure question, I have an aversion to drilling into guns.

It depends on how old. I believe mounts to replace the rear sight are available for 686-4 and newer. 1994 or so ? I am not that familiar with serial numbers to tell you. Model # is visible with cylinder open.

Weigand mount for all smith L frames:

He has been providing mounts for the bullseye community for years!

His site says that all smith revolvers since 1992 have had the holes already drilled for mounting this type of mount. You could call and verify.

I have a -5 model and it's pre-drilled for a Weigand type mount. You have to remove the read sight and also use that hole. Easy and very durable mount.

BPK serial prefix dates your gun to very late 93, early 94. -4 started in 93. A -4 has the rounded rear sight leaf and is factory tapped underneath it for a sight mount.

You are right on the break from -3 to -4 which as stated above would be factory drilled and tapped. I have several Earlier 686's that have been drilled and tapped by my gunsmith with absolutely no problem I had him position the holes as not to disturb the original sight leaf screw in case I decided to install the original sights back on. D&T won't change the strength of the frame nor will it effect the resale of the gun down the road. If anything I think it might ad value since it gives the owner more than one choice for sights. I think my gunsmith charges me $25 per hole. I always take the rail I'm going to use so it will be a perfect fit

No it can not, not if you have to drill, not if you want to maintain a clear conscience:-D

If your talking a pre-lock 686 I really would leave it alone. But if it’s a more recent model with the internal key lock, go right ahead and drill if you have to!


Sorry, I know that wasn’t much help.
