It makes sense to me for pistol calibers, but seems like a waste of powder and velocity for rifle.

I mostly want to do it for fun, but I'll be doing it to my 9mm... not that I won't list a few other calibers on the paperwork... you know, in case I have a change of heart. I hardly ever shoot that dinky 223 anymore, now that I have a 308. Why dick around?

For around the house, I have an 18 1/2" 12 gauge.

Yeah this makes no sense. Shortening a barrel doesn't make it less lethal.

Shortening a barrel reduces muzzle velocity. The lower muzzle velocity, the shorter range at which a 5.56 FMJ round will fragment. If I recall correctly, a 7.5" barreled AR will never cause a 5.56 FMJ round to fragment, while a 10.5" will fragment at 50yds or so. A 20" M16 will fragment at like 200 yds? And if a 5.56mm round doesn't fragment, it just puts a .22" hole into someone, give or take, with a little tumbling action too.

Now a JHP or JSP round doesn't require fragmentation and will expand even out of a 7.5" AR, so there's always that. But with mil rounds, you need more velocity.

Super Dave - Yeah, I'm considering changing my SBR into a pistol caliber.

Ok maybe less lethal isn't the proper phrase though striving for less bullet velocity from a rifle and paying the govt $200 bucks to do it makes no sense to me but then again......

This from robar-g19:

SBR'ing has much more to do with the "coolness factor" in a civilian rifle than anything else.

I would pay the $200 tax stamp for a select fire AR15 with a short barrel. :o)

Makes more sense than buying a $2500 brand name AR, or a $5000 1911....

Where does the tax go that you pay for those? It sure as hell doesn't go to me...lol

You get the Stamp that costs $200.00.

If you ever decide to get rid of your registered item, there are stamp collectors that will buy the stamp from you.

That's pretty cool that you can at least get some of your money back if you ever decide to sell your NFA item.
