Swivel stud to rail adapter?

Johnny Sasaki · Mar 31, 2012

Anyway to remove a swivel stud and put a picatinny rail in it's place, or is there at least some sort of adapter? I found this, but it looks like it adds quite a bit.

I was looking for something a little more flush.

Re: Swivel stud to rail adapter?

Yes, there are a few. Fewer that are:

1. A robust solution that work off solely the stud.
2. That do not require a secondary support attachment point that...
3. Requires some alteration of the stock that....
4. May require some structural strengthening inside the forearm.

But it really depends on:

1. What fore end?
2. What device are you attaching to the rail?
3. Will you require a swivel stud to be retained as well?
4. Etc.

As examples to get your hopes up:

Some of those look doable. Thanks.

Wouldn't happen to know if Atlas makes a bipod with a swivel stud mount do you? That would make this a lot easier.

Best way to go...

Thanks for the replies guys. I didn't think atlas didn't make a swivel stud mount for their bipods, so if they're not already done building my rifle, I'll just call up and see if they can install a rail instead. It's a lot easier to find a rail mounted swivel stud than the other way around apparently.

I ordered the Weaver system.

Attaches right to the stud.

Piece of cake.

As you said - if your rifle hasn't been completed I'd recommend that you have a Rail installed. If you want a BT17 like 427Cobra posted a link to, I'm selling a Birdsong Black-T-coated BT17 with Black-T-coated 10-32 screws in my "WTS: Black-T coated ACCU-SHOT BT17 & Screws" thread. You can avoid the Birdsong wait, and my asking price is well below what it would cost to buy a BT17 and the Screws, send them to Birdsong for coating, and pay shipping. You just need a pair of 10-32 T-Nuts.

However, if your stock hasn't been made yet and/or your builder hasn't finished filling, bedding, painting it yet, you can also have an Anschutz Rail installed in your stock, then use an "Atlas BT28 AFAR Kit" in the Anschutz Rail. This route is more expensive and time-consuming, but it's also a cleaner, more elegant method of attaching a Rail to the bottom of the forearm than a BT17. About a year ago I bought a McMillan A5 with the KMW "Loggerhead" Adjustable Cheekpiece from a Hide member. A BT17 had been mounted on the bottom, but I decided to have a 10" Anschutz Rail installed like on my Tac Ops X-Ray 51.

Given the choice of filling said holes and drilling new holes and installing new T-Nuts or inletting an Anschutz Rail into the forearm and using a BT28 I chose the latter, since the stock needed other work such as opening-up the barrel channel and re-inletting the floorplate area. My stock was sent back to McMillan to have the barrel channel and floorplate re-inletted and to have a 10" Anschutz Rail installed. Below are some before & after photos of the stock, as well as some finished photos.

Keith,

Very nicely done. In the absence of the rail add-on, the remaining flush rail allows for bag shooting. Really the way to go.

May I ask what they charged for the inletting?

Thanks RollingThunder51. I always shoot off a bipod, but as you surmised I can remove the BT28 and let the forearm ride directly on a bag or other support without the Rail hanging-up on anything.

I don't remember the exact breakdown, and I'm out of town right now so I can't refer to the invoice but I know that the total was $161.00. That includes inletting and installing the Anschutz Rail, re-inletting the barrel channel, and re-inletting the floorplate area from a (Remington) BDL floorplate to a Williams floorplate. However, IIRC, the inletting for the barrel channel and the floorplate were $59.00 each, and the Anschutz Rail installation was $53.00 complete with Rail ($59.00 + $59.00 + $53.00 = $161.00).

Note that the close-fit of the Tac Ops floorplate and of the "timed" screws on the Anschutz Rail seen in the "in-the-white" and finished photos are attributable to Tac Ops fit and finish, not due to McMillan's inletting (sorry, Kelly). Of course, the closest fit and smallest details always require hand-fitting, and the Tac Ops floorplate inlet is a little different from that of the Williams.
