    Got it and I think it is great input.

    308 Semi Auto

    I know I'm swimming against the tide here, but just for kicks...

    I think Norway and Mexico speak well to the reliability of the delayed roller lock system. Do any countries utilize a .308 AR as a weapon system? Current PTRs come with an optics rail and a paddle mag release which addresses some of the ergo issues. The correct Manual of Arms makes reaching the safety easy. I admit ergos are not great, charging handle etc. But, weight is the same as an AR-10,9.5 lbs. 40inch OAL with a 18inch barrel. A base model PTR can be found for under $900. A fluted 16in. barrel model runs $1,300. Denny Williams will do a very nice set trigger for $280. Mags are less than $10. Seems well within the OP's price range.

    I know it's not as accurate or ergo as an AR-10, but is a 91 obsolete as a general purpose rifle? No I don't work for PTR, 8 years ago when I had a $1,000 budget for a semi .308 a PTR seemed to make the most sense. At that time AR-10 were very hit or miss, I know they continue to improve and they will be the answer some day, Has that day come yet?

    3-4" is standard scope eye relief. Scout scopes have intermediate relief usually. Pistol scopes have long eye relief. Standard is definitely faster.

    Scouts are usually referred to as intermediate eye relief. Pistol scopes are long eye relief, and everything else is, I guess, normal.

    I am much faster with a scout scope, except when the sun is at my back, so I keep my shadow behind me.

    Good input thanks. It seems really hard to find any high round count reviews of any AR-10.

    A properly built G3 variant isn't going to get you "kilt in da streetz" any more than an AK but I've been there and done that and IME AR-10 > G3. Same for the FAL and M1A/M14.

    Mexico, Norway and many other countries adopted the G3 decades ago when 7.62x51 battle rifles as general issue were a thing. That time has passed. Most military's are only acquiring new 7.62x51 rifles in a Designated Marksman Rifle (DMR) or Semi Auto Sniper System (SASS) role. The US KAC M110 and the UK / New Zealand use of the LMT MWS would be the largest scale use of the AR-10 in those roles.

    The only exceptions I know of are the SCAR 17 in limited use by USSOCCOM as a battle rifle and the Turks. The Turks are transitioning from locally produced G3's and HK33's to a license produced HK 416 and a locally produced variant of the HK 417.

    Norway issues the HK 416 5.56. The Mexican Navy and Marines use M16's, The Mexican Army is transitioning to a Mexican made G36 knock off.

    You will see G-3's hang around in specialized roles in places which issued them like Germany, Norway etc because they are "in the system", the same reason you still see M-14's in use by US forces.

    The current Armalite company in IL has been building AR-10 for over 20 years now and they have learned a few things and made improvements along the way. Their current guns (anything from the last 10 -15 years) run well.

    There is a thread on M4C by a guy who ran a Ruger SR 762 for a couple years, including 800 or 900 rounds in a Pat McNamara Carbine class:

    The pat mac class info is around page 26 or 27.

    S.W.A.T. magazine did a review of several .308 ARs in 2013. It was an interesting article and may be worth a read for the OP.

    https://www.swatmag.com/issues/view/...omparison_test

    As I recall, the Armalite rifle was well received by the reviewers. I shot and handled an older model and it was a nice rifle. Plus, now the newer version, which I believe is the "B" model uses the standard P-Mags available versus the old M14 mags.

    I've been interested in a .308 AR myself, but other than using it for a range toy it would have no practical use. If I lived in an area with large bears or other animals, then I would pick one up.

    Armalite has been around a while making these rifles, so it stands to reason they do likely know what they are doing.

    P.S. The LMT is nice, but very heavy and over $2K.
