Sabre Defense ? building AR15

[f4t9r]

Got great help from everyone on building a AR 15
Went with Rock River Lower and got talked into a barrel from
Sabre Defense suspose to be chrome lined in a mid length
I cant find a whole lot about it
Is this a good idea ??
and do I need accuwedge bushing for barrel ?

Going from memory here, but I think Sabre is a fairly new entrant on the market. I've not heard anything bad about them.

They have been in business for a long time doing mil procurement stuff, they have only recently gotten into the civillian market. From what I understand they have been doing barrels for a very long time.

I have not owned any of their guns, but I've been very impressed with what I've seen so far.

The only thing an Accuwedge does is tighten the fit between the upper and lower receivers. Some people find them useful; but I've found that if they improve accuracy any it is to such a small degree that I cannot notice the difference with my shooting and I've done the occasional sub-MOA AR group at 100yds.

I am interested in any experiences with mid-length gas systems, so if anyone could share them with me I would appreciate it.

do I need accuwedge bushing for barrel ?

As BR pointed out, an accuwedge is used to tighten up the fit between the upper and lower receivers. It has nothing to do with the barrel and does nothing to improve the function or accuracy of an AR. That said, many people like me hate when the upper\lower rattle. An accuwedge is one way to fix that. A #7 O-Ring around the front take-down lug does the same thing a lot cheaper.

Considering you are using an RRA lower, I doubt that will be a problem for you. Almost all uppers sit very tightly on RRA lowers. Sometimes, the uppers are too tight on RRA lowers and need a little adjustment (i.e. filing on the rear take-down lug) in order to fit correctly.

Also as pointed out already, Sabre is new in the civilian AR world but have been making barrels (mostly machine gun barrels) for government contracts for a long time now. A number of people on AR15.com have bought one of their mid-length barrels and so far the reports are positive

Right on cvg69 the accuwedge was to tight even after cutting it down
gun seems very tight so the wedge is headed for the trash

I just converted my last carbine-gas system AR to a midlength. It was my favorite AR so I was loathe to mess with it; but I really do like the midlength system. I now own several 16" ARs, all mids.

I originally thought it was a good idea; but saw no reason to change until a friend bought an Armalite midlength. After getting to shoot that rifle, I was sold on the concept.

Better sight radius, less wear and tear on parts due to lower cycling pressures and a noticeably softer recoil impluse that translates into better split times (though we are still talking hundredths and tenths of a second). All of this with the same length and handling of a carbine.

I'm another big fan of the mid-length. To me, if your want a 16" AR then there is no good reason not to go Mid-length (as opposed to carbine length gas system.)

Softer recoil, Less stress on the action, better reliability, longer site radius, more of the barrel covered, If you use a rail system, you will have more real estate to hang crap from and the all important ability to mount a standard bayonet

Seriously all of these advantages are relatively small by themselves but added together I think they are significant and best of all, there is no downside at all.

 

[Bartholomew Roberts]

Yes, I think that is one of the key points in the popularity of the midlength. It isn't like the midlength is a revolutionary thing; but you get all the pluses without any of the minuses .

The worst thing you could say about a midlength is that it might be an ounce or two heavier from the extra handguard length and it could theoretically be harder to get replacement/new parts for it since it hasn't been around as long. However, I can already think of at least six manufacturers (Sabre Defence, CavArms, Rock River, Armalite, CMMG) offering midlengths and more are jumping on that bandwagon every day. On top of that practically every foreend manufacturer out there has a midlength product (9" rail).

All in all, not too bad of a trade.

Thank you!

Considering a 16" HBAR and I think if I go forward with it I will go mid-length.

With a shaved FSB and a LaRue 12.0, since this would replace my 20" A2 profile barrel.

Decisions, decisions...

 

[Bartholomew Roberts]

With a shaved FSB and a LaRue 12.0, since this would replace my 20" A2 profile barrel.

If you go with a shaved gas block and a flip front on a Larue 12.0, you'll lose a 1.2" of sight radius compared to a 20" with A2 front sight base... which is why Larue makes a 13.2 foreend now. It also works with a 16" midlength.

 

[NMshooter]

Well, yes, but since I already have the 12.0...

The real problem with me getting the 13.2 is that it would end up on the AR-10, requiring me to get two!

I really need more money...

Or maybe a less expensive habit, no, wait, cars are DEFINITELY more expensive, hmmm, have to think on this one...

OK, I really need more money...

Jeff Quinn at Gunblast.com just reveiwed the Sabre AR. He, apparently, liked the product.
