    I have heard about there being problems, especially with mags and feeding, in a lot of different .308 AR rifles. Is this true, or internet myth? Outside of the costly rifles like Knights, are there quality, reliable, AR .308s for reasonable prices?

    If you get one think of it as a hobby..

    I would look at the Larue OBR I like it so much I have one on order ... a 18 inch version.

    Stay away from DPMS they just don't hold a candle to the Armalites in Quality of materials...

    I would go Armalite or Larue..

    Knights are pie in the sky expensive.

    I'll add another recomendation for the Armalite AR-10. I've had an AR-10T for several years, and it's never skipped a beat. I'm thinking about getting the carbine version of the same in the near future as the target version is pretty heavy, but will keep up with a lot of bolt action "sniper" rifles.

    No experiance with the DPMS units, but have checked them out at the local gun shop, and I just don't like them...

    My only gripe is that the AR-10 won't take regular M1A mags, so I had to buy extras, and they aren't cheap, but are (or at least were) readily availble.

    Not a cheap unit to feed, so take that into consideration when purchasing any semi-auto .308.

    My personal opinion is that for a semi-.308 you'd be better off going with a different (dedicated .308) platform like the M14 or HK91.

    I've heard and seen plenty of issues with .308 AR-pattern weapons....DPMS mags, Bushmaster bolts, and a co-worker even had feed and mag probs with his AR10T.

    I've wanted a semi-.308 for a long time, but have never had the $$ for the HK, PTR, M14 variants I'd want....I'm more interested in the cartridge as a precision/distance weapon than an MBR.

    The 6.8SPC, 6.5 Grendel, .458 SOCOM....3 different cartridges, each with more oomph than the 5.56, with 3 different strengths (antipersonnel, long range accuracy, anti-dinosaur)....each in my experience run better in the AR platform than the .308.

    Lastly, it's not an especially accurate weapon, but 2 friends bought the Saiga .308 and love it.

    The problem with the DPMS is the mags. Get Pmags in .308 flavor though and it works just fine.

    Agreed. The design of the AR-10 platform simply does not allow it to keep up with highend semi-autos and bolt rifles. This was true a few years ago and probably still is...when was the last time a competition was won with a semi-auto? Never.

    I say this lightly, because I'm sure lots of people would disagree. But that is simply the nature of a semi-auto, the tolerances must be looser in order to accommodate cycling.

    My particular DPMS AP4 cycles just fine and shoots sub 1.5MOA groups with the iron sights. That doesn't mean that its better than the Armalite, LaRue, etc., but if you simply want one for a range toy, zombie blaster, or occassional hog slammer, in my experience the DPMS works just fine.

    There's a lot more problems with the DPMS LR's than just the mags. We tried running them on our team and they made so many trips back to the factory that we should've gotten frequent flier miles. One went back 5x for extraction problems, one was back 2x. They finally just replaced both uppers.

    Mine ran okay, but I had a lot of upgrades done to it by Noveske. After he was done screwing with it he said he would never work on a LR308 again.

    The accuracy can be good, but it isn't very consistent. CBS were always wandering and I could tell which side of the mag the round fed out of by examining the target.

    We dumped them and went back to bolt guns. I would get a LaRue OBR if I had the funds.

    I bought two Knight's when they were available. One heavy rifle and one carbine. The carbine has a lot of recoil. Knight's claims that private sales were just to work out the bugs and concentrates on military sales now. I'm not sure a "new" Knight's is even available but they might be. I have one AR10 which is the AR10b model with the cocking handle on the top. It has been 100% but Armalite has since discontinued this model. I bought a DPMS only because it was so cheap. It came really bad plastic magazines. They now offer better steel magazines but they won't take military ammunition because it's loaded to long. The Knight's magazines work in it, but like the rifles, I don't know if Knight's magazine are available any longer. The Fulton Armory rifles are exactly the same as DPMS rifles.

    maybe I am a snob, so take this with a grain or ten of salt.

    if I am buying an Ar-based weapon in 308, it will not be for "plinking" or kicks and giggles. It will be for accuracy, and competition.

    If it will not shoot sub-moa, I dont want it. That pretty much leaves me with the armalite AR-10T, larue, or try to find a Knights that works. LMT is bringing a 308 to market, and so is LWRC, and hopefully those will be accurate guns.

    From everything I have seen, the Armalite is the top dog right now in terms of reliability and accuracy.

    When I bought my first Knight's I wanted to buy another upper for it. At the time Knight's told me that I would have to send the rifle and the extra upper would have to fitted to the lower. Okay I understand tight fits and everything. Well I put it off for a couple of years. Knight's then tells me they no longer offer additional uppers. I did find a solution though. Armalite started making drop in uppers for the Knight's rifles, not just their own rifles which are different. I bought a Knight's type upper from Armalite. That was great. I'm not sure Armalite still offers Knight's type uppers anymore though. Knight's is terrible to try to buy parts from.

    I just received my DPMS SASS .308 tact rifle last week....all I can say is wow..:wow: was very impressed w/ the build/quality of this thing. Was initially told that there would be a 12-14 month waiting if I placed my order through my FFL....and after a search on it! (along w/ my Ruger SuperRedhawk Alaskan .454 Casull :whistling:)

    It's been a snow-pocalypse currently so having to just admire it for now....cmon spring!!!

    I've seen thousands of rounds run reliably through the OBR.

    And they shoot sub-minute if the shooter has a clue.

    KAC finally got the SR-25 working right, but it took years (and many of them at war) to get it right.

    I have been pretty set on wanting a .308 ar platfrom but I was looking mostly at the Rock River Lar-8. Has anyone heard anything good or bad about them, I have only heard great things about Rock River in general but havent heard anything about the LAr-8 specifically.

    I was very fortunate to pickup this older KAC SR-25 Mk11 Mod 0 (24" bbl) a couple years ago. It is sinfully accurate.

    Keep an eye on the SI Defense. i got to see their AR10 lowers & matching uppers made from one piece billet aluminum at the SAR & SHOT Shows!! Looked great!!

    I will likely have one for T&E in the next few weeks. Unlike CMMG, they are going info production with this model that takes HK91/G3 mags and DPMS lower parts kits!!!!!!! :wavey:

    Did I mention I have a few of those 20rd aluminum HK91/G3mags????:whistling:
