Cheap is good Tyler cause I am sure the DPMS will shoot it.

Having carried Colt's, owning a Bushmaster and currently owning a DPMS, I would buy another DPMS hands down. I would really love to purchase the DPMS AP4 in .308. Hate getting my balls busted on other forums for owning a DPMS but I think they are great rifles.

I went to the range this morning with the new .308 DPMS, and overall had a very good range session. The gun functioned flawlessly. No FTF or FTE's. The gun ate everything it was fed. I tried both DPMS magazines that came with the rifle and both fed 19 rounds each of Magtech 150 Gr. FMJ without a hitch. I then switched to the Mag-Pul P-Mag I had for all the rest of my shooting, because that is the magazine I will be purchasing several extras of. It ran fine with everything I stuffed in it.

At 8.25 pounds empty, the gun has very manageable recoil. Much less than a light .308 sporter like my Winchester Model 88 does. It was LOUD! Much louder than any .223 AR-15. Ejection was positive, but it did not damage or ding any of the brass. I don't have any optics on this rifle, and really don't intend to mount any. The standard A-2 sights were pretty close at 100 yards, where all my shooting was from. I had to adjust about 2 inches up and about 2 to 3 inches to the left, and everything after that was well central on the targets.

After about 50 rounds I switched to some handloads I had brought that were loaded with 42.0 Gr. of Varget under a Sierra 168 Gr. Matchking bullet. My eyes were getting used to the sights, and using the small aperture shooting off the bench it was not difficult to get groups that could be covered with a drink coaster. For my 59 year old ageing eyes I'll call that good. I switched to some Hornady 168 Gr. A-Max bullets loaded with the same 42.0 Gr. of Varget. They grouped just a bit tighter, but I would of had to have a scope mounted to really establish which was the better load as far as accuracy.

After taking a break and BS'ing with some of the guys there I tried some informal offhand shooting on the 200 yards steel plates. It was very easy to achieve steady hits. This rifle is very easy to shoot accurately. Much more so than my Springfield M1-A's are offhand. It being shorter is far less muzzle heavy and less tiresome to shoot from an offhand stance. All in all I ran a total of 220 rounds through the gun. More .308 than I normally would shoot at a single range outing.

Before I left I heavily lubed up everything, and after every 30 rounds or so, I gave the bolt and bolt lugs several drops of Mobil 1 to keep everything good and slick. After I got home the gun cleaned up effortlessly. Everyone has their own method of lubricating AR's. For me more is better. I disassembled the bolt carrier group and washed everything in clean Kerosene, then blew everything dry with compressed air. I then re oiled and greased everything, and the gun was as spotless as before I took it out of the case.

I used Bore Tech Eliminator in the barrel, and it cleaned up much easier than I had expected. I didn't get the barrel very hot, and gave it plenty of time to cool off between magazines. It was mostly cloudy and cool out with almost no wind at all. Overall I'm very pleased with this rifle. The gun ran perfectly, shot where it was aimed, and was easy to handle doing it. I wished I hadn't waited so long to get into the .308 AR game. These guns are a lot of fun, and I couldn't be more pleased.

Thanks for the report billt. Sounds like a real winner in the stable. Curious I have found bore-snakes make life easier than regular rods, do you use them?

I too want a .308 AR,...and really want to build one like my 5.56 build last year. I want to try the longer barrel version similar to the LWRC REPR, (without the LWRC price)....

but a nice DPMS like yours would be a great foundation to start with,...as it can always be tweaked...

Thanks again for the report.

I've always been meaning to try them, but I haven't gotten around to it yet. I'm really sold on Bore Tech Eliminator for getting rid of copper fouling. It won't harm your barrel or gas system, and it has no Ammonia in it. The stuff is completely odorless, and even has rust inhibitors in it. It cleaned up the barrel on my DPMS in no time. Just be sure to only use a nylon brush with it. It will dissolve a bronze brush in no time!

Ammonia-LOL!  Reminded me of my youth,12 or 13, when my dad was on the Army Reserve shooting team and he was cleaning his rifle, M1 I think, one Monday afternoon after a match.  He calls me over, "smell this..."  I stuck my nose in and took a BIG whiff-YAWL!  I don't remember where I went but I know I ended up outside on the far end of the house with needles poking out my head and my mom holding me tight.  Concentrated ammonia, mom was pissed and I never forgot that valuable lesson, getting your kids to smell nasty stuff is fun! ;D

Oh yeah.... and if you are smelling something you're not sure of- NEVER smell it directly from the container, wave it to your nose with your hand and GENTLY sniff.

 :)I have the heavy barrel, 24", LR308, and it is great.
I shoot 40 grains IMR 4895, Sierra 168 g HPBT, and it will shoot 10 rounds into less than 1" all day.
I usually am under 5/8".  It has about 2000 rounds through the barrel now.
Last Saturday I put 8 rounds into 3/8" at 100 yards, then I pulled the last two out for a 5/8" group.
Federal Match, with the Sierra 168 grain HPBT shoots very well as a factory load.
Just for your info, I have been trying the CFE223 powder, but I am not really impressed with it.
The barrel cleans up very quick and easy, but the groups give some vertical stringing, compared to the IMR 4895.
I am using the Millet LRS1 scope with the 1/10 click adjustments.  Works great :)
I also use a Geissele National Match trigger. (1st stage 1#8oz, 2nd stage 6oz, total 2#4oz., really works well)
I would suggest a wedge, it tightens up the halves very well.

This is it after I installed the Vltor E-Mod Stock on it. Since then I've also added an Ergo Grip from Falcon Industries. It really improves the feel of the rifle.

The ERGO Grip by Falcon Ind. is what I put on my Frankenstein AR. Sooooooo much better than the standard grip. Also went with the VLTOR E-Mod.....Great minds think alike.... 8)

Any thoughts on the handguard? Keep it, go vented? Mine started like yours, but got damn hot after repetitive fire. I than put the YHM vented carbine quad rail with the rubber ladder panels to keep the grip without the "edges". I was just curious, as rapid fire has got to get that grip hot...

Thus far the forend has been fine. I don't shoot too much rapid fire. At least not enough to heat the handguard to the point of it being uncomfortable. The only thing I don't like is I wish it had a sling swivel or 2 for mounting a bi pod. It would have been easy enough to put on.
