ST Compressor SBR (NFA)

http://www.spikestactical.com/new/z/st-compressor-sbr-nfa-p-491.html

I'm looking for a short barrel AR15 for my first AR15. It might end up being my only AR15 I get, but I haven't decided yet.

I don't need a 500+ yard gun. 200-300 yards or more is plenty for me or any use I would have for it even in SHTF. Since AR's don't have folding stocks, I'd prefer to keep it shorter with the shorter barrel. I also want a suppressor on it so it's not so loud on my ears.

So this is not a cheap rifle. At 2600.00 it would be by far my most expensive firearm. Spikes has a good reputation for quality and I've considered their Mid length as well, but I'm not sure how expensive changing the rifle into the SBR's model would cost.

I am looking for quality parts, and definitely a SBR with a suppressor. I'm guessing it would have to be shipped to an FFL that does class 3 or maybe it can go to any FFL. I'm not sure yet, but also won't be buying it or the parts for 3 months.

Are there better alternatives? If I can get quality parts for less money that is preferable for sure, but not against buying once and crying once on this. I've put off buying an AR15 for a long time.

What parts would I need to buy to shoot 5.45x39? I have a butt load of that ammo around. Just an upper or just a barrel?


Sorry for the long thread and thanks for the help :wavey:

Is that barrel long enough so I wouldn't have reliability issues?

I see Daniel Defense also sells AR15's

what would it cost to add a suppressor and such on this one?

5.56MM is a velocity dependant round. Going with the short barrel loses you a lot of the velocity.

And costs waaaaaay more.

If what you want is terminal performance at 300 yards, you're doing it wrong.

If what you really want is a suppressed SBR AR, it looks like a good choice.

As far as the 5.45 ammo goes, I don't think you will be using that stuff in your SBR without a 2nd tax stamp. Others will be along to explain the why and how, or correct me if I'm wrong, but there are a lot of laws with SBRs.

I have yet to hear of anyone that has that rifle. The idea certainly intrigues me but the $2600 price tag and $400 in tax stamps needed to get it are certainly obstacles. Even though the suppressor is integrated in the gun you will need a separate tax stamp for it. So $200 for the suppressor and $200 for the SBR. Do some goolging on NFA laws. My recommendation is that unless you CLEO is very NFA friendly(hint, almost none are as they think signing the paperwork somehow makes them responsible) go with a trust. They are easy and cheap to set up. Also more than one person can be on a trust and it also makes it easy to pass on collection when you pass on.

Personally I would skip the Spykes, from that I an seeing they are using an 8.1" barrel on it. For an entry only gun that may work, not for many other people though.

I am simple, just buy a Daniel Defense MK18 SBR's rifle. Now you need a suppressor. Surefire is making incredibly small options. They have a model that extendes you length 4". Now with length your not going to be getting the best suppresson in the world. The have offer models were can meet in the middle. That is the route I would do myself.

As far as the second upper goes (I can't speak to the first part of your question). You'll need a different barrel and bolt, you'll also need a stronger hammer spring for the surplus ammo.

If you are going to make that second upper an SBR you won't need to pay for a second tax stamp, I was told by the ATF to just send them a letter stating the additional upper and the lengths that would be involved and you'll be fine (as long as you have already registered the weapon as an SBR). Others have said that the letter is not needed as long as you keep the upper that you originally registered the gun with... I figure it can't hurt to cover my butt a bit...

I'd recommend looking for somewhere to shoot a .556 AR suppressed before you shell out $4K + optics on a SBR AR and suppressor only to be disappointed with performance and sound reduction.

For that kind of money, I'd buy a basic 16" carbine for your first AR and suppress one in 9mm.

Great advice in this thread. Honestly OP the 5.56 is terrible under 10" of barrel. The round does not even stabilize consistently and the lack of power is punishing to call it a viable option for defense.

If you want to go with a short 8" barrel then I would recommend the 300 AAC Blackout with a good 30 cal suppressor. Not that I don't love my 10" suppressed 5.56 w/ an AAC M4-2000 suppressor but there is nothing quiet about the 5.56 even with a can on it.

Best Advice.

For an all purpose, do everything rifle- 14.5-16" AR.

For running suppressed, at a pleasing report, and at a price you can do a lot of shooting- 9mm AR.

To go the distance, have effects on target, and still be quiet, .300 AAC.

I don't need my suppressed gun to really go the distance, or kill when it gets there... and I want common, available, cheap ammo... so I love my 9mm. (And I can shoot it on pistol ranges/ indoors)

10 inches would be stable like the daniel defense sbr? That's a price range that may be better as well. Can they ship the barrel threaded or is that something my gun shop would have to do?

That one is 10 inches long. Are all the parts standard except for the shorter barrel?

Depends if the build is done correctly. Generally the gas port & gas tube are a little different size to compensate for the barrel length and a heavier buffer is used.

Noveske is probably my favorite for a 10" design as they have pretty much mastered the art of SBRs and run without a hitch out of the box. But that's not to say you could not build one yourself but like I said, AR's can be a little fickle in SBR form. Buy once cry once and you will be glad you did.

Here are my two Noveske SBRs (both are 10") one is a 5.56 w/ Switchblock (An ABSOLUTE blessing when you are suppressing a 5.56 cartridge due to reducing all blowback from gas pressure caused by the suppressor) and the other is a Noveske 300 Blackout. I use AAC suppressors for both. Like I said Both are exceptional... if I had to choose between the two I would definitely go with the 300 Blackout. I will probably have an 8" version of the 300 Blackout shortly w/ a Gen II Noveske lower. The switchblock will allow you to switch from suppressed to unsuppressed shooting at the turn of a dial. Keeps the exact amount of gas for firing in each configuration.

Here is a close-up of the Noveske Switchblock. No more gas blowback hitting you in the eyes and no more increased wear on the bolt assembly due to suppressed fire.

also look at a lwrc psd in 6.8 if you want a sbr or go with a 16" upper in either 6.8 or .300 aac/blk and get a .30 caliber suppressor. the ballistics for .300 aac/blackout and 6.8 are similar, the bullets for the .300 weigh more.

AR's don't use threaded barrels. They attach via the flashhider/comp. Some attach to the stangdard A2 but most have their own custom flashhider. This is a much better route than threaded attachments, it's quicker with less zero shift typically and also what zero shift there is is repeatable.

 

[Tech knight]

It looks like I have some more research to do

 

[KalashniKEV]

AR's don't use threaded barrels. They attach via the flashhider/comp.

Actually there are a number of suppressors designed to mount directly to 1/2-28 threads, like the Ranger-2.
