Bud K Tube Adapter,Sling Swivel,Tool Parts (2PCS)

Works great at adding a single point sling option to any AR. I put one on my AR Pistol.

This item fit perfectly on my AR. fits nice and tight on a KAK buffer tube nut. I read several reviews where people had to shim the nut to get it to fit tightly, but I didn't have that issue. I plan on buying an end plate with the quick connect port, but in the meantime this will work nicely. You don't have to take your buffer tube off to make this work which is a nice alternative. I just assembled this particular lower so I don't want to take it back apart quite yet. I would recommend this to anyone looking for a fast functional fit. Most importantly, it doesn't interfere with your hand when placed on the grip. Can't even tell that it's there.

Looks good but I thought it was a castle nut with hook loops but it’s not. I believe this fits over the castle nut and you use provided allen wrench to tighten the 2 bolts to lock it down nice and tight. Came with no instructions so I will find out when my castle nuts come in.

I got 4 of these for different rifles. I wasnt too sure how they would be. Theyre great. I have installed 2. One fit perfect. I had to shim the other to make it good and tight. But Im pretty sure thats because of the castle nut. Not this product. I would definately buy again!

Awesome

buffer tube nuts are all the same size; when this is tightened to it's maximum point it is not tight enough to grip the nut. it slides right off. two pack straight in the trash.

This is a good alternative to not having to retighten the buffer. It tightens down very tight with no slipping of the sling attached to it, very solid.
