I have finally found the answer for all Baikal MP-153 and Remington SPR453 owners who would like a sling on their Russian semi-auto. Below is a small "how-to" for installing the sling swivels on your shotgun. There may be a better way to do this, but I haven't found it yet.



Gear List:
You will need...
Uncle Mike's Quick Detachable Super Swivels model 1001-2 for bolt action rifles.
Vice
Hacksaw
Drill
3/16" drill bit
5/32" drill bit
1/4" drill bit
Loctite
Needlenose pliers


Below is a picture of the sling kit I used.



Step 1:
Remove the threaded stud and nut from the package and screw the nut onto the threaded stud as far down as it will go.



Step 2:
Place the stud with the nut screwed down in a vice. If you are concerned about hurting the finish on the stud use a towel.



Step 3:
Cut the stud flush with the nut.



Step 4:
Unscrew the nut off of the stud.



Step 5:
Take a 3/16" drill bit and drill the hole out that is already in the end of the magazine cap. I did have to use the vice to hold the cap even though it is not shown in the picture.



Step 6:
Hold the nut in the end of the magazine cap where it lines up with the hole you drilled. Put some Loctite on the threads of the stud and screw it into the nut that you are holding in the magazine cap. You will probably need the needlenose pliers to get it tight. Screw the magazine cap back onto the gun. I recommend using a small screwdriver that will fit through the hole that is in the stud so that you can twist it back and forth until you have it lined up the way you want it. When you are finished your cap should look just like the one below.



Installing the second swivel stud in the buttstock:
I did not take pictures of installing the stud in the buttstock because it is pretty self explanatory. However, I'll go ahead and tell you the size of drill bits I used and the depth that I drilled into the stock.

First, I would suggest that you get no closer to the recoil pad than 2" on the synthetic stock and 2.5" on a wood stock. This will prevent cracking the synthetic or splitting the wood.

Second, drill a pilot hole in the buttstock with the 5/32" bit about 5/8" deep.

Third, use the 5/8" bit to drill a hole about 1/4" deep. This will help get the stud started.

Fourth, screw the stud into the buttsock by hand. When you can no longer do it by hand use the small screwdriver mentioned earlier to finish screwing it down.

Now your Baikal/Remington is outfitted with something it should have come with from the factory. I hope this "how-to" has helped you out.
