I am thinking of buying a NOS Super Grade that has the BOSS knob on the barrel.(Probably the reason it's never sold!)

Is it threaded on or soldered? Either way, it's got to go and am wondering what I'm getting involved with.

TIA

They are threaded on.

The ugly part of it just unscrews.
Unless you want little threaded fingers stickin g out the end of your BOSS-less barrel, I highhly recommend a small cut and recrowning job.

So you arent getting into anything serious.

you can have a cap made for about $20.00 to cover the threads and conform to the barrel, properly done you can hardly see it or just cut and crown the barrel behind the threads..I'd leave it on for bench work...

Thanks, that was basically what I was wanting to know. If it just unscrews and leaves a threaded stub, I can make a thread cover for the end. If the barrel has some Rube Goldberg foolishness out on the end that I can't cover, then we'll circumcise it!

Good luck finding a metric tap for cutting a thread protector with. They used a real bastardized thread size for the boss. Its .600 OD x somewhere between 1.0 & 1.25mm. I believe that the lawyers wanted to make certain that NOTHING other than a BOSS could be screwed onto their rifles. You can always recut the threaded stub to .500 & thread to 28tpi & machine a 1/2"x28tpi protector which is what i do.

Tell you what I did, I had a buddy of mine put it on his lathe and turn it down to barrel coutour (the BOSS) and then cut it to length. He cut it .030 long and I filed it the rest of the way. It is a stainless barrel so we just bead blasted the cap and you can't tell where it is unless you look real close. We were going to make a cap but we measured the threads and the were 9/16 fine if I remember right. The tap would have cost me 15 bucks, so we just cut the BOSS down instead.
