I have a 15-22 on the way (my debit card was charged yesterday). Could someone measure the outside barrel diameter for me, please?
Thanks!
Thanks!

I got .669
I bored out one for a 10/22 and slid it on.

If you don't want to thread the barrel, there is an adapter on ebay for flash hiders.
Thanks y'all. I saw the adaptor on eBay but if I decide to do this I'd rather just step the barrel down and thread it. The good news is the barrel will fit through the head stock spindle on our metal lathe.
Right now I’m waiting impatiently for the big brown truck to bless me with its presence.

I sent my barrel out for threading. Only downside is when the flash hider is on the barrel the handguard end cap won't slide over it and also the 3/4" pvc tool that's takes off the barrel nut won't go over the flash hider either. Basically the flash hider has to be removed any time the gun is disassembled. Thankfully I don't plan on removing the barrel many times if at all.
the 1 i made chatanoogaphil should slide right through with no problems.. u may wanna ask him but im almost pos.

No problem... the PVC slips right over Belt_Fed's suppressor.

I think the issue is that the handguard cap won't slide over the muzzle device.
Since you can't access the barrel nut without removing the handguard cap and you can't remove the barrel without removing the muzzle device to clear the handguard cap, it goes to reason that the only way to remove the barrel is to remove the muzzle device.
Or perhaps you could just throw away the handguard cap before re-installing the barrel and muzzle device, but I suspect is might be there to support the handguard...

Boring out a standard M16 compensator works. The problem is you have to cement three (3) parts to the barrel as the "grenade" rings are deeper than the barrel diameter. Or you can just bore out part way to the first ring and glue it just at the muzzle.
Here's the three-part version. It got bored out too large and never fit right though. Be more careful and keep checking the fit of the parts and you'll have better results.
and here's the same rifle with a threaded barrel and M16A1 compensator:
Note how the slip-on version shortens the overall length of the barrel.

...and a backwards crush washer.
That bottom picture is of a different barrel with a different flash hider. The Smith does need a special outer diameter crush washer. I can't find 'em tho.

OK, I reversed the crush washer.
Used my last peel washer a while ago and couldn't find an M16A1 lock washer. Figured I had a 50-50 chance!

Indeed it's a different barrel, but the crush washer is properly installed.
There's no need for a special outer diameter crush washer as crush washers are tapered.
You put the small end towards the barrel and the large end towards the muzzle device.

AR15Barrels,
Crush Vs. Peel, is there any preference, any reason to chose one over the other? Are the Peel Washers reusable since they don't "crush" ?

If you use a crush washer on your 15-22.. be sure to use a barrel vise or strap or you will need a new reciever... looks like chuck is using one for tention but if you try to index a flash hider use some supporet or peel washers

Belt Fed,
Great tip for those who may be reading and try to chuck up the upper in a vice using receiver jaws... A big No/No... And I don't like the idea of clamping on the barrel! I think I will go the peel washer route myself.
