View Full Version : 11.5" or 14.5" AR and why?

Ok, I've applied for my Tax Stamp and I am currently in the middle of my SBR AR project. The question is which barrel length to install? I stated on the application form that it is an 11.5” barrel, but I have been informed (still to be confirmed) that anything longer then 11.5” is acceptable, as long as you don’t go below the registered length.

So, I am now considering a 14.5”. Why? Obviously there are advantages to both.

If you have had experience with one or the other and or would have done something different, please share your views.

Yes, it does depend on what I am going to do with the gun. In general, it would just be for a bit of fun. I would still like it to be semi accurate out to 200 yards, I am not looking for a tack driver, nor a ‘shotgun’ either.

Any help greatly appreciated.

The 14.5" allows you to affix a bayonet :rolleyes: ...

PS 14.5" is also M4-length, if having a military-type weapon is of interest.

The 14.5" was a better choice for me because the the 14.5" is a better compromise than the 16" for CQB in terms of balance and maneuverability. The difference in muzzle velocity lost is negligible.

The 11.5 with silencer is not so long.

Guys,

Thanks for all the input.

It did cross my mind :D was concerned about accuracy to 200 yards with this setup.

The other side of my dilemma.

The 11.5 looks kewl! There is no real difference between the 14.5 to 16, so why bother.

I always thought it was a waste of $200 just to lose 1 1/2" of barrel. Now, go down to 7.5" and that's something....:eek:

14.5,right in the middle, can't go wrong.

14.5 doesn't offer that much of an advantage over the 16 inch barrel, unless you want a dimensionally accurate M4gery.

The 11.5 provides a distinct advantage in handling, especially with a Noveske muzzle device.

Personally I'd go with the 11.5 with a Gemtech M4-02 "muzzle device." :DI only have a RRA 16;" however, I really like the way my M4-02 quiets down my PLR-16. I think an 11.5 inch SBR will be the next project after I get my 870 SBS paperwork back. It has only been 2 weeks but seems like forever.:rolleyes:

I don't know how I missed that the first time around, but you can go shorter or longer, either way without problems.
