.308 noob questions...sorry in advance

[6shootr]

went to two local gun stores.  Walked in and said, have any AR's in .308?  All i got from both places was a...hahahaha.  I guess best bet is building one myself then if that is the case lol

[edgecrusher]

i'll check for you,  ::), nothing up my sleeve, or is there? oh, by the way we can have sbr's in mass. just saying.

[6shootr]

I'd appreciate that! shoot me a pm if it's easier.  i'm going back and forth between buying one all set and putting one together because the store made it seem like they're hard to come by.  we can get sbr's?!?  That's news to me! i've only seen them in stores in NH.I'd love one of those!

[edgecrusher]

yupper's, we sure can! i am waiting on a set of billet receiver's from our mega group buy, and i plan on registering the lower, ( previously unreleased info!) and doing two uppers dedicated to that lower, a 14.5" match in .223 wylde and a sbr of undetermined size as of yet.

all you have to do is go to your local pd, fill out the paperwork, get the approval of your chief, pay the man, and wait for your stamp, then BAM, sbr baby  <lmao> <thumbsup>

[6shootr]

poop that's awesome! i'm definitely going to have to do that. I know exactly how i'd want one set up to.  That's another project i guess haha.

My ffl will be glad to do GB transfers, that's how I picked up my HK USC carbine, and I know some ffl's who give a hard time about that

only thing is i've heard rock river isn't that great and do the CMMG and armalite lowers take that g3 make everyone hates?

[edgecrusher]

Lets back up a bit.

1. Rock river makes a fine lar-8 rifle. It's a shooter for sure, but some may badmouth it because it's a proprietary system, meaning Rra parts only. Doesn't mean the rifle is bad

2. Armalite rifles are under similar circumstances, until recently, when they came out with pmag comaptible rifles. Also very good quality.

3. The old cmmg that uses the g3 mags had issues and never really caught on, but that shouldn't be confused with the new mk3 lowers which seem to be made well.

Be careful interpreting the info that's out there, many a yahoos voice their opinion far too often, don't drink the kool aid.

[6shootr]

thanks for the clearup!  yea i agree that's why i figured i'd post everything i'm considering and doing to get feedback because a lot of people that post don't know their ass from their elbow and may of not even owned a gun themselves.  RRA may be hard then because if i do buy one put together i intend on slowly changing some stuff out.  I'll have to keep an eye out for those mk3 lowers.  I'm honestly not 100% sure if i'm building or buying off the shelf yet. 

[edgecrusher]

No problem, there is a lot of info to take in. Ian going to call my ffl for you tomorrow, I know she has a mk3 lower but I can't remember if its a carbine or rifle setup. Ill ask about the lr308b also.

As far as Rra, they are fine weapons but like dpms there is a wait. Unless you can find one in the wild.

[6shootr]

great! thanks a lot i appreciate that.  I'm just browsing midway usa and dpms right now and im around $1600 with everything that i can think of needing (i'm sure i missed something though; at least little springs and stuff like that.  Can we have adjustable cheek rests on the stock in MA or is that considered a collapsible stock?

Thank you,  but only for my concern that Toby is being fed too <laughs>

Yes adjustable cheek rests are ok. I like my magpul prs. If you are going carbine,  I run a co-witnessed eotech on my Pws with a magpul acs that lines up nicely. I can't link you to it from my phone (at work ) but larue has a ctr /riser combo too.

Missing anything?  I know i'm missing a quad rail but that i'm not sure what direction i'm going yet.

[imschur]

I know there have been some positive comments here about the Rainier Select but personally I would go up to a Rainier Ultra Match or a Fulton Criterion. Both are made from known premium blanks. The selects are hit and miss like other similarly priced barrels. Ultra Match Shilen Criterion is Krieger. jmho

Also a Fulton upper will give you more handguard options thana DPMS

what robo is trying to say is that your buffer tube and stock must match, either both commercial or both mil-spec. i called my ffl and she's looking into the dpms, the mk3 cmmg lower is a complete rifle lower with a2 stock, for $420. did you try linking to the tactical machining site through the forum side bar? they have stripped dpms style lowers for $229 and stripped uppers for $199. that's pretty good, and they will match, no mixing manufacturer's, which is always a plus. who makes the trigger you listed?

pm me  and we can get a good detailed list going, or if you are available to talk i will be around the next few days starting tomorrow before i work a marathon of 14 out of 16 days, all 12 hr shifts starting this weekend

[Robocop1051]

You can have a mil buffer tube and a commercial stock, but it'll rattle around. That gets annoying real fast.

Mil spec is slightly thinner than the commercial stuff. There is absolutely no reason to have one over the other. Just preference.

I didn't even notice that haha thanks for pointing that out.  I'd like to go with mil spec with everything

[6shootr]

trigger was just a gold one that was listed on brownells...used that more for a money reference then a trigger i would actually put in the gun.

[LocoGringo]

A "standard" DPMS is far from insufficient. A target DPMS barrel will shoot a MOA or better.

Aftermarket barrels can increase accuracy, but only if the shooter is capable. If you can't shoot MOA with a DPMS barrel, upgrading it wont make you a better shot.

I'm late to this thread, but I gotta take issue with the first 2 sentences.  I bought a base model DPMS LR-308 with the 24" bull barrel about 4 years ago.  I went through the "break-in" process and babied the hell out of that barrel.  I used only match ammo after I finished the break-in and I never got consistent results out of that barrel.  I would get some great individual shots, but groups were awful.  I even had it re-crowned and eventually contoured to an H-bar, but nothing improved.  I finally gave up on the stock barrel and replaced it with a Criterion stainless steel for $300 and, WOW, the difference!  Shooting the same ammo with the same rate of twist in both barrels, there was no comparison.  The Criterion SMOKED the stock DPMS. 

I'd say a more accurate statement would be that the stock DPMS barrels are hit and miss.  I've heard a lot of success stories, but I've also heard several stories similar to mine.  I got the 18.5" Criterion match quality and am thrilled. 

As far as going DI or piston, I'm having an adjustable gas block installed and anticipate excellent function and accuracy with a suppressor on a DI rifle.  The adjustable gas block I bought is the PRI steel model for $85 at MidwayUSA.com.  If you're going for lightweight, piston isn't the way to go.  Piston runs cooler and cleaner, but not lighter.  Good luck with your build or purchase.

I believe Fulton armory sells criterion match barrels, and for $300, it can't be beat  <thumbsup>

thanks a bunch for the info.  After that comment and what i've heard so far i think building one from scratch is probably the way to go.  Only reason i'm considering piston over DI is because this gun may be getting dirty and i may add a suppressor in the future.  What kind of yardage are you shooting at with the new barrel and what groupings?  Just seeing what i should expect with a little practice.
