Tactictal Solutions scope base does not fit!



Log in to see fewer ads
I got the short, low profile Tactical solutions scope base and the sucker is approximately 0.035 too long. It hits the rear sight and screw holes will not line up.

It is anodized aluminum, so; no I have to try and use a small end mill to carefully remove 35+/- thou and leave the corners so the un-anodized area does not show.

This is the name of the part, I found on eBay:

Tactical Solutions Aluminum Pac-Lite Standard Scope Base Rail Black Ruger MKIII

Maybe these are different than a Mk IV, hunter base? Hole spacing and receiver curvature is perfect but the length is just ever so too long.

I got the base fitted and it turns out the screw pitch is different. I called TS and they are sending me three screws. Great service and apparently a pac-lite is something different .... The tech guy knew right away what I had and what I needed.

This is one reason why I don't buy from eBay.

Dinosaur? Probably.

Either way, glad TacSol is sorting it out with you.

If you have to shorten the rail a little and you expose bare aluminum, use aluminum black to cover it up. It should work to hide the bare metal.

Thanks I do have some of that on hand. I cut it so close and with an angle ot the corners you cannot (or hardly) see the aluminum. Noes not touch the sight either. But, I want to prevent corrosion, so; will do.

I think the hole spacing is right on and the three holes (Ruger holes) are located a bit rear of where they were on the sample TS worked from. I am guessing. It seems all the aftermarket vendors have to suffer this misery. The better and closer fit they strive for the more problems. The VQ trigger kit just had to be expanded with two more parts.

Apparently that rail was made for the Tac-Sol aftermarket receiver/barrels. They are tapped #6-40, not #6-48 as Ruger uses for all of the factory d&t Mk-series guns so that's why the screws didn't fit.

I am satisfied with this purchase. I expect some others might not be willing to deal with the length problem or have the patience to wait on the screws. More facts up front would simple have resulted in no need for posting on my part. I would still buy this mount if it is available for any future Mk IV. Ok, one difference, next time, I would call TS and see if they had one with the right screws and length. I expect not.

I believe this is correct. And correct on the screw pitch.

I did a search when I purchased this one and could not find another anywhere. It maybe a 'dinosaur', as SailDesign suggested. If I do see anther, I may grab it up as a spare.

Was actually suggesting that I might be a dinosaur, for not using eBay.

But I know what you mean.

I used the Ruger low profil base that was provided with the MkIII comp on that pistol. I trim that flush with the receiver. That was silver and I left the cut edge in the white. That was more complicated because I also had to cut an additional cross slot. I then found the Ruger slots in this base were too shallow for some (or many) weaver style rings. The alternative big ruger base is ugly.

This TS base is just what I want. Except the obvious minor mod, its perfect. It is low and flush with the receiver. The slots are cut deep enough and the spacing is fully utilized with slots, like a pitcanary(?) rail, without the ugly.

I maybe a dinosaur myself. I had a hard time to navigate the TS website. I dont know what else they have to offer. Initial impression is a good company.

I had the Ruger one on my old Mk III 22/45, and cut it down (black Sharpie on the cut to match perfectly!), but sold it with the gun. The Mk IV has a TandemKross shorty base that fit perfectly. This one,

Ah, thank you - bookmarked. If I get another MkIII or IV I will use that base.

Tac-Sol provides #6-40 threads for their base to be used on their aluminum, steel sleeved, uppers. The #6-40, courser thread, is less likely to "strip out" in aluminum when tightened down, as the finer #6-48 thread often will.
Was waiting to see if that info got posted, but......................
I was curious. That explains the why of that.

No need to be bashful. Speak right up Just kidding.
