I am new to ARs and was wondering how a person can get an AR with a barrel shorter than 14.5’ without the extender bringing the total length to 16"?
Also, how or can a person buy a suppressor for an AR? 
The more I learn or hear about ARs the more questions I come up with and the more my interest in ARs grow.
There’s an entire forum dedicated to the type of weapons you’re interested. These items fall under the NFA jurisdiction and yes a civillian can own them by filling out the proper forms and pay the $200 tax per item. You’ll get to become acquainted with the term “Trust” 
14.5" barrels = SBR = short barrel rifle = NFA item
Suppressor = NFA item

Thanks for the clarification of terms. Helps to know what I am talking about or looking for when searching the net and forums.
Thanks for the hyperlink. The website answers all my questions and now I can stop bothering forum members:p
Is it any harder to build an SBR than a standard lenght AR? If so what are the problems and how hard are they to overcome? I am getting the Black Rifle Disease and I amtrying to get as much information as I can so I can start researching what I will need to get the three types of rifels I think I want. 1. SBR 2. Standard length 3. SPR.:eek:
No not really, you just have to pay more attention to the quality of the items you are using. Cheap SBR’s tend not to run all that well.
For a 10.5, I would look at LMT and Noveske.

Can you suggest a good place I can find information on quality parts for an SBR either on this forum or on the internet? Here is a really stupid question. The onlly difference between a standard AR and an SBR is that the barrel is shorter and should be stainless steel? Or have I missed other significant points?
Make your life easier, just order everything from Grant, he’ll steer you straight.
The most significant point is the gas port size, IMO. As the barrel gets shorter, the amount of gas diverted to the gas system becomes more and more important. You’ll probably want a heavier buffer, too.
The type of steel is irrelevant. None of my SBR’s have stainless barrels. I can’t say I’ve ever seen an AR with a stainless barrel less than 16" long, but I’m sure there are some out there.
We sell and build SBR. Give us a call to discuss what you want to do.

Thanks. I have added your website to my favorites and will contact you soon. Just to get me in the right frame of mind how much on average does a SBR cost. Does your company also do standard or SPRs? If so what are the average prices for standard and/or SPRs? Thanks very much for your time.
Well it really depends on what components you select. You can get into a LMT upper for around $619.
We build just about every AR configuration there is. There really is no standard pricing as everything is generally built from scratch per order.

The only difference is that the barrel is shorter.
The choice of chrome-lined or stainless is a preferencial thing.
The main advantage of stainless is accuracy.
The main use of an SBR is usually not in a role where accuracy is a premium requirement.
Chrome lined barrels are more popular on SBR’s for their extended life and ability to be run hard and hot.
2011bldr, who I won’t refer to by name, sure seems to have lots of first hand evidence to the contrary that the 10.5" chrome lined barrels last longer than 10.5 SS barrels.
Does your company build entire weapons or just components of weapons that some else has to put together? Isnt it cheaper to buy seperate components and not have to pay some sort of tax?
Would I have to have that NAF forum filled out and approved before ordering a SBR or components? Thanks for the information concerning barrel use in a SBR.
You would need your NFA form completed and stamp affixed before you can legally construct (pin the upper to the lower) an SBR.
There is no paperwork requirement to buy all the pieces.
It’s up to YOU to follow the laws and not assemble an illegal gun without the proper paperwork being in-place.
My advice is to build yourself a regular gun.
Then you can do all the NFA paperwork to register the lower as an SBR. (this will generally take a few months for BATFE approval once you submit your fingerprints and get the sheriff or police chief to sign your form 1)
Then you can add a shorty upper to the existing lower.
If you want seperate guns, it’s easy enough to just buy more lowers.
The neat thing about AR’s is that you could have one lower, register it as an SBR and then three different uppers, a shorty, a regular carbine and an SPR type.
Within 15 seconds, you can swap uppers back and forth.
I’d wait to buy the upper until you have your approved paperwork back from ATF. People have been convicted for merely possessing a short upper when they also had a non-SBR lower but no other lower on which they could legally install the upper (e.g., US v Kent). This is the concept of constructive possession.
If, for some reason, there is a short upper you must buy earlier because it won’t be available later or is on some super-hot discount, I’d have it shipped separately and stored separately (i.e., at the house of a friend who doesn’t have any AR lowers) until your SBR is approved.
That said, AR15barrels knows much more about SBRs than I do. Nevertheless, I felt compelled to mention constructive possession out of an abundance of caution.
Buy a Colt 6921 and get a near MILSPEC solution, instead of a Frankengun.
