SBR

goodburbon · Apr 1, 2009

All of this SBR talk has me wondering 2 things

1. If a longer barrel increases muzzle velocity, range, and accuracy, why would one go short?

2. Why on earth is it illegal without special gov permission. (rhetorical, I know our gun laws make no sense)

I understand that a shorter weapon is better for clearing buildings, but there are pistol caliber carbines that are better suited to the task.

I guess I can understand people wanting them because they can have them, but I can't come up with any other reason why.

One of the things you want to consider is fragmentation. Also lower velocity isn't a bad thing when clearing a building. You don't want to over penetrate a target. As far as the pistol carbines, that's a question for the LEO guys that do SWAT. If you'll notice in recent years everyone is switching to carbines from MP5 type sub-machine guns. There is evidently an advantage.

Also think about suppressor use. If you are doing CQB work inside of a building, entering doors and rounding corners and you have a 20" barrel with a 6-8" suppressor its going to be difficult.

Wheras a 9-12.5" barrel with a 8" suppressor is still shorter than a standard government profile A2 rifle. Even a 14.5" profiled barrel with the average 5.56 suppressor probably being 6.8" you are over 20" total.

Right, Like I said, I understand them being used for building clearing. So how many of you building SBRs are clearing buildings with them since that appears to be the only use mentioned so far?

Remember I'm not against anyone owning them, I dont' even understand why they are restricted. Why would I want one?

Self-defense. CQB in your own house if you have an intruder. Most people don't need a 20" government profiled barrel to shoot 100 yards, which is consistent with most of the range options we have.

And if you are shooting with a suppressor you don't suffer the consequences of the short barrel as much as without it.

Did I mention a 25" AR that will fit in a tennis case is cool?

Not as much of an effect on velocity as you would imagine. http://counterstrikefox.freeservers.com/mv.htm

There is also more damage from the bullet in its intended fragmentation range.

I can shoot in any direction from my driver's seat with my 9.25" AR. With the suppressor attached I can quickly and efficiently clear my house. Best of all, I can toss the whole rig in a tennis bag for some real low key urban camouflage. After Gustav I kept it on my arm in the tennis bag 100% of the time until power was restored to my house (three weeks later).

The cool thing about an AR-15 SBR is you can make it any caliber you want. Shoot varmints or squirrels with .22LR? Yep. Turn it into a 9mm subgun? Yep. 12 gauge beltfed? Yep.

I would figure they are restricted, because as TDH mentions above, you can very easily conceal them, under a coat, in a tennis racket bag, etc...

why would you want one? well for the same above reasons, and the fact that they just look cool, chicks dig them, and if you don't have a SBR you will not stand a chance during the zombie invasion, regardless of how much training/ammo/non-NFA weapons you have

You won't even need ammo. As soon as they see the intimidating weapon the zombies will turn and flee.

The best reason is a short rifle makes your penis look and feel longer.

But does a short penis make my rifle look and feel longer? Richard?

Damn, I guess so. I was figuring that would be a question He'd ask the 6th grade class

Neither is referring to the size (or lack thereof) of my penis

Because chicks dig 'em (SBR's, not short penises) :rofl:

It's all about a bullpup.

I think the overall length of a 16" barrel AUG is 27 or 28 inches.

An MSAR or TPD AXR is high up on my wishlist :cool:

Yeah they are nice, but all of the ones I've seen crack eventually. That's what turned me away from them.

I like the FS2000's too but keep turning my nose up at them.

I gas I haven't read up enough. . .
