View Full Version : Where to buy a complete AR upper?

Exactly what the title says. Where is the cheapest place to buy a complete upper assembly for an AR?

Depends on what you want, really.

Do you want a light or heavy barrel, 16 inch or 20 ?

Do you want it free floated, and if so, do you want a RIS on it too ?

Standard 16 inch upper a3 flat top. I am working on a sbr build and want to see if it is cheaper to get a full size upper and cut the barrel down to 12 inches. I am not sure you can do this anyway. I posted another thread on the nfa forum asking this question.

Don't cut the barrel down on an AR unless you know what you're doing. If it's not done right, the weapon won't cycle properly. Just to keep everything legal, buy the SBR upper as a complete unit and pay the $200 tax stamp. No need for the law to come a-knockin'.

As already said, don't cut the barrel. You can buy a barrel the length (or close enough) you want. The gas port on a 16" barrel is not going to be the correct size needed to function a 12" barrel.

Foe cheapest place to buy a upper check these out...

Ah yes the old saying; "buy cheap, buy twice."

It will always be cheaper to just buy a 12" barrel than to buy any other length and have it cut down simply for the reason that you will need to re-thread the barrel (which adds to the cost).

SBR are VERY finicky creatures. Very few companies build them properly and none of the companies that build them the proper way are cheap.

Choose wisely.

As some of the others have mentioned, (for a variety of reasons) you will be much better off getting a barrel the length you want it in the first place than buying a 16" or 20" and then cutting it down.

Also as some have posted, if you don't build it right it will be a nightmare to make it run properly.

When it comes to firearms, "least expensive" or "cheapest" is rarely a true bargain. On the other hand there is no reason to have to spend $1,200 on just an upper to get it to run right either, $475 including the charging handle and bolt carrier will do it very nicely, and if you shop carefully, you can get it at that price with a lifetime warranty too.

Hope this information is useful.

I am waiting on the paperwork to do my build. I was just asking is it cheaper if at all possible to buy a full size upper and cut it down rathan than buy a short upper?
the 11.5 inch upper on bushmaster's webstie doesn't come with a charging handle or bolt assembly. In total it costs a little over $600.00.
I do not want to buy a cheap piece of junk that will not work. I will be using this at work on our SRT team. I am a breacher and get stuck toting around a 14 inch remington 870 while everyone else has UMP 40's and M-4's. Low man on the totem pole I guess.
My Sheriff's Office does not have a patrol rifle program yet but we are working on that. recently we got a couple of surplus m-16's from the govt with the intent when the program is implemented the shift sergeants will have them. I am a Corporal so I won't get one of those. Since I am on SRT I can qualify with my own rifle and also carry it on duty.

Why not just get the 16 inch then?

This will get rid of the legalities of your department using a SBR (I'm not sure you've considered this), you don't have to pay the $200 tax stamp, and it'll save you some money on something more common.

You're basically talking about 4 inches of barrel, and if you use a 6 position tele-stock on your lower it makes it less of an issue. You also can get more range out of it if you need to as a patrol vehicle weapon.

As I sort of mentioned, without trying to appear to be blaitently advertising on a board that we are not actually a member of:

11.5" flat top upper
Chrome lined barrel
A2 front sight
Bolt carrier assembly and charging handle
Lifetime warranty: $475

Optional Folding front sight/gas block $75


Does that help any?

Don't just get the cheapest. Get the cheapest of the best! ;)
