Might work on most tubes
Not sure how it works with most buffer tubes, but do not try to put this on the cerakoted timber creek buffer tubes. I got it on by about 4 threads and it seized. I think the cerakote is gumming up the threads, but I'm not 100% sure; either way, I had to cut it off.
Idk if the problem is the castle nut or the buffer tube, but might as well leave the review on both so no one makes the same mistake I did.
That said, colonel mustard is great, shipping was fast, I'll definitely order from here again.
