6.5 Creedmoor AR 308

[dsdmmat]

well the barrel and handguard came in early so it looks like I should be able to test the 6.5 CM in an autoloader before Christmas. The barrel is an Oden Works 22 inch 1-8 twist tactical match profile with an extra long rifle gas port. The gas tube and adjustable gas block were supplied with the barrel. Also picked up a Strike industries Ultimate Dust Cover to try out.

Wish I could stop by for a tutorial in putting one of these together properly.

Any time you wish. They are pretty simple, nothing like the ones you build. I call them the Adult Legos.

Both of my kids have built their own so that proves how easy they are.

@Robin an AR pattern rifle would be a breeze for you based on the gorgeous rifles you create. Build your first and you’ll wonder why you waited so long. LOTS of great videos on YouTube (including a series from Brownells) literally take you step by step.

I have done lower but never a upper. I do have books on how to

 

[Airborneguy]

Yeah, dude it’s easy. I taught myself using youtube. I remember my first time messing with the trigger. That was super no bueno in the Army. The hardest part was overcoming my ingrained aversion to touching those parts.

 

[Jaywmustang]

i am afraid the upper would blow up on me lol. Gas system and head space concerns me

Also very easy.

 

[Jaywmustang]

I had ga precision build my 308 upper......got it just before the safe act passed. Never shot it

 

[Sweetyzfd]

Yep, YouTube it and you’ll be a pro in no time

@dsdmmat, I have a 6.5 upper. Shoots amazing. Scary how accurate they are. I can get 2 rounds off and see/hear them hammer at 1k. Probably could get 3 off. Much fun. Way better than 308 at distance. They hit way harder too. Congrats!!!

Dropped in a Geissele G2S & never looked back. Maybe a bit more money than some, but I love it. And I don't need to worry about whether I screwed something up.

 

[dsdmmat]

Well just got back fron the range with a mixed report.

The good:
The Odin works barrel is accurate as all get out as my last three sighters at 100 were touching (federal American Eagle 140 gr OTM) The rifle is very soft shooting and I am very pleased with it.

The bad:
The Odin works adjustable gas block is a beautiful piece but it is also a pain in the ass. The adjustment screw/ lock screw relationship is different from all of the other adjustable gas blocks I have ever used.
The lock screw goes in the same hole and locks the adjustment screw by sitting on top of it not allowing it to back out. I found that the lock screw would turn the adjustment screw in about 1/4-1/2 turn before tightening up. I ended up dropping the lock screw in the snow and that was the end of the range day for the rifle. I went to the local hardware store and was able to get a stainless steel replacement screw for 70 cents. I actually got 5 of them for good measure.

Small thing for sure but I like that dust cover.

Your going to love the 6.5. I have the first DPMS Creedmoore and it awsome.

I got into the Creedmoor in January this year with the Savage model 10 FCP-SR, then I bought a model 12 LRP in 6.5CM and I sent off my LRB M25 to be rebarreled to 6.5CM (should be back before too much longer I figure another 6 weeks). So the AR 308 in 6.5CM was the next logical purchase.

I had not planned on building anymore AR 308s but, the best laid plans of mice and men are often thwarted. I don't really shoot the AR15 type rifles much any more. I will do experiments with heavy loads like 80 and 90 grain 223s or shoot the 300 BLK from time to time but, the normal .223 Rem/5.56 NATO round isn't really that appealing anymore. Since most of my shooting is from the bench my AR15 type rifles see very little range time, aside from the military shoots my club holds in the spring/summer they are relegated to other duties around the home.

My first impression of the AR 308 in 6.5CM was very good, I only fired 14 rounds (Factory Ammo) before the range session ended. All but 2 were at 100 yards so I have not seen what it is capable of out to 400 yards yet. If it can hold the x ring at 400 I may use it in the Club's scoped rifle shoots this spring/summer. Wouldn't that be a hoot, a semi outshooting a few bench rest rifles on a weekly basis?

OK, really dumb question; I know that "real" 5.56 chambers are somewhat sloppy to allow for crap, but I would suspect a 6.5 CM chamber is much the same whether a bolt gun or an autoloader. If you closed off the gas block and manually cycled the gun, why couldn't you use "fire formed" cases like with a regular bolt gun?

I suppose you could but, eventually you would have to full length size them because, they will grow even if it is a miniscule amount. I am going to grab the cases fired from the AR and check the measurement at shoulder compared to my bolt guns to see what the difference is if any.

I have bolt action 5.56 ARs (no gas port in the barrel) but, I full length size the brass when I reload for them as I do for all of my normal bolt guns. I went down the neck size only path for a while only to come back to full length sizing because I didn't see any gain by neck sizing only. In my 30-06 the neck size only rounds actually grouped looser than full length sized rounds.

Use the RCA adjustable gas key. A far better option IMO!

Not a lot of info on that savage fcp-sr 6.5cm.

What kind of info are you looking for?

 

[Jaywmustang]

Savage doesn’t have it listed on their site. Did your come fluted?

nope

 

[Jaywmustang]

There also isn’t a lot of reviews on the rifle. Are you shooting factory ammo out of yours?

Some, I also have a load worked up for it. Factory loads I shoot Federal American Eagle 140 gr OTM. For hand loads I load a 140 grain Hornady 140 gr HPBT match bullet over IMR 4350 in Federal cases.

How do u like the accustock?

Hated it. Too light in the ass end and the recoil pad felt like a soggy roll of toilet paper. I tried dumping 5 pounds of shot in the butt and that worked for the balance but the recoil pad there was no cure. So I put a bell and Carlson stock on it.

Lol I am not impressed with it. Probably going to throw mine in my mdt chassis when it gets here.

I am willing to give mine to anyone who wants it. That is how impressed I am with it. LOL

Lol I hate the magazine system. I have it on my 223...... I hate it so much I almost didn’t buy this rifle.
