"12"

[constructor]

This is the AR-12 for a familier term, it is between the AR10 and AR15 in size and weight.
7.5lbs with a 18" mid weight 308 barrel before optics, lightweight 16" barrel would get it down to around 7lbs before the MCD. It pins to a DPMS 308 lower,uses their 308 mags, the rails or handguards are AR15s for lighter weight, more choices and less cost. I have hated the heavy DPMS 308s and AR10s for years, this is my answer to the heavy 308 class of rifles. We can chamber them in 308, 260, 7mm-08, 243, 6.5x47 lapua, 6x47 Lapua at this time. An upper with production grade 308 barrel nitrocarburized and VTAC 13" Extreme rail will start at $1259 complete, PacNor or Shilen barrel start at $1459, Krieger or Bartlein barrel $1499. muzzle devices extra.

EDITED to add function test video, 16" 308- 7.5 lbs MCD brake seems to be working.

Zestay !!! Nice tidy stick

[constructor]

Getting the weight down was the main consideration so no frills.

Sweet. My credit card is getting nervous:{)

[OC455]

Very nice H. I would say that there boom stick would be lighter with an ACS on it for a stock....or the 16 inch version....that would probably be nice and light....

[Clint]

Nice H.

Where do cases land w/o the deflector?

[Megalos]

I just salivated all over my key board.

[Colohunter]

Very nice looking rifle, the 308 caliber AR market is looking even better to me now.

[marinesg1012]

I cant wait for the 18 inch 7mm-08 version....

Would the 358 Win be a good candidate for use in a light-weight? I know that there are a few out there chambered in 338 Federal, so would a 358 Win work alright or do you think the shoulder area might be a touch too small? Up here in Alaska the 358 would be very useful where a 308 is somewhat marginal at times.

Large calibers cause feeding issues because the bullets hit the front ribs of the mags and tend to push the bullet tips to the center of the mag, if the mags can be altered to accept the large bullet then it should be possible.

[jdgilbert]

What is your ETA on these and do you have an approximate price? A guy at work is planning on getting a Rock River .308 in time for hunting season (October-ish) but I would rather point him your direction for the .308 if I can't talk him into the 6.8 :a06:

[constructor]

These things are $1400 uppers only with a rifle length VTAC rail, I know Noveske sells 5.56 uppers for that but these are expensive and is really only figured as machine time cost.

pretty plain jane, 6-22x Nightforce,18" mid gas 308(95 Palma chamber) Pac Nor 5R -11.25 twist. HUGE JP ent. adj gas block, same GG&G bipod.
This one may get cut down to 16" and any 18-20" from now on will have a rifle gas system. 7.5lbs before scope or bipod.http://i208.photobucket.com/albums/bb218/constructor2007/2010-06-25164714.jpg

Damn sweet !!!

[marinesg1012]

you think the rifle is better then the midlength for an 18 inch?

I think it will delay the carrier movement a little more, increasing accuracy and will let the pressure subside a little in the case so extraction is easier. A 16" mid gas should have the same delay and would make a lightweight hunter.
I tried some surplus aluminum cased 308 in the match chamber, it stuck so the only thing I can use that ammo in is the HK.

Finished a 7mm-08 and 6.5x47 for the "12", and a 6x47 for my AI chassis system today. Have to do another 6BRX tomorrow before the fight party, I hope Carwin is ready.

[marinesg1012]

Hows the 7mm shooting? I think I am going to stick with that one, maybe pick up a 65x47 later on if I build a precision ar10 lower...

IF carwin can keep it on his feet and show brock he can overpower him we may have a fight....

H- You will need to come out to NH for one of my fight nights.....

[constructor]

I haven't shot any of those yet, I have to wait until the nuts go back to work on Monday.
The 7mm AR10 I built a few weeks ago was easy to tune with Sierras but didn't shoot so great with the 140 Barnes, I'm sure it's just a matter of tweaking things but, they are expensive and I just didn't have the time to mess with them.

I am very interested in a 7mm-08 in a clean no frills package like in your picture. Please take lots of pictures when you are wringing these out, and lots of detailed notes, etc. Have to start socking away the coin...

Well Lesnar kept the belt due to a choke hold in the second round but Carwin beat the crap out of Lesnar, had him on the ground in the fetal position and hit him about 50-60 times. Any other ref would have stopped it after the 10th punch but after 50 or 60 Carwin was gassed and never recovered. The same dumb ref called a fight 2 nights ago because one guy ran across the ring to get away from the other guy and wasn't even hit. Anyway Lesnar knew he got the crap kicked out of him so it was worth it.

[marinesg1012]

I saw the fight (well the power cut out right at the start of the second round and when it came back on he had already won)

Carwin had to hit him harder on the ground for the ref to stop that fight... arm punches dont stop fights, it has always been my feeling if your fighting for the title you let trhe guys hurt eachother a little more then you would in a none title fight.... I wouldnt of stopped it but IF carwin would of gotten some good ground and pound OR let the dude up to knock him back down again he probably could of won that fight. That choke was weak and giving him submission of the night when there was two other submissions that were a million times more technacal is BS in my opinion....

[Dipper]

It was a good fight..... Lesnar got the crap beat out of him in the 1st round for sure..... I have seen UFC fights stopped for less.
There was a point when Lesnar just tried to cover up and took about 10 shots to the head.
I give Lesnar credit for having a decent chin.

If Carwin wouldn't have gotten gassed, the fight would have ended differently.... he was all done in by the end of the 1st round.

The rematch should be good...... I think Carwin will be better prepared and won't have the same problem again.

I noticed in the 1st round that Lesnar could not throw Carwin around like he did Mir for example.... Lesnar could not get Carwin on the ground until he was gassed... when he did get Carwin down, he tried to roll him and hold him with one arm and hit him with the other like he did Mir... he couldn't do it.
I think Lesnar has met someone that is his equal.

Just as Lesnar lost his 1st fight with Mir, Carwin lost his 1st to Lesnar.

I think the rematch will have a different result.

[Ratdog68]

Lookin' forward to seein' it on the re-runs. I got mixed feelings on Lesnar. I'm glad to see him back in the saddle after bein' ill... but, that whole WWE background he brings... ack. I saw Carwin in his UFC debut, he did pretty good. The heavy weight division's been needin' some fresh blood for a while now. Can't really blame him for gassin' though... I'd gas too, trying to beat on that skull of Lesnar's.

Quick function test video, 16 " 7.5lb 308 with a MCD up front, looks like it's keeping the muzzle down.

Man who cuts your hair??/LOL!!!!!!


Nice did you bounce the first round off of a plate or did the case hit something next to the camera? I like the way the MCD is working.

Do these fit the MA-TEN's from Mega as well as the DPMS?

[constructor]

The Megas are like Armalite with a angle bottom receiver, so these fit DPMS or any with a curved bottom receiver.
Dude I am 48, just glad I have hair:a01:

[Aramark]

looks very good

[Ratdog68]

Looks like the MCD does hold it down nicely... looked to me like the first brass casing flipped back to 4:00 and "gonged" on something below/left of the camer.

Hair? I remember that stuff bein' on my head... nowadays... it's growin' out my ears/nose instead. LOL And, why didn't they tell me about ivy-like eyebrows when you get older?

Probably the metal chair next to the bench, they use C channels with RR ties in front of them to hold the target stands up and I was shooting at a steel silhouette out at 100yds.

How's the recoil in a 2 lb lighter gun? Didn't look too bad in the video.

[Drifter]

I like the looks (and weight) of the "12".

Of the .260, 7mm-08, and .308, which is most efficient in shorter barrels (16"-18") losing less percentage of their velocity...?

[marinesg1012]

I need to shoot my 12 more in 7mm-08.... I really like it so far I just need to shoot it more to get a good report together.

[constructor]

The recoil was quite a bit more than a 6.8 when I was running a target crown and no muzzle device, the MCD that is on it has larger ports than what we sell, you can see it pushing the muzzle down with every shot so I may need to plug a hole or two on the top side. As that rifle is set up it is completely controllable offhand.

The 308 is more efficient due to the larger bore, 125-150gr bullets work best to keep the velocities up IMO.

130gr Barnes TTSX would be the monster load, IMHO...

If I hunted with a 308 that is exactly what I would use.
