    I installed an adams arms retrofit on my sabre mid length 6.5. Would not stop jamming, even after it was sent to adams. Bought a new bolt from aa, dropped it in, and never jammed again. food for thought.

    for anyone wishing for the 6.5, build one yourself.
    saber barrel, Adams Arms Mid length gas piston conversion, their tech dept has comments on this conversion. seems to work quite well. i have found good pricing on the Adams conversion.

    I called AA mid decemeber and was told the carrier group has a 12-14 week back order, I have seen two sold on gunbroker for alot more than the listed price for those who do not want to wait

    I ordered the gas upper about nine months ago. I have called the office twice about delivery. The gals were pleasent to speak with, but some how you new they were tired answering the same questions (Delivery is behind) I still hanen’t seen the finished product.

    One year later…what AA 6.5G piston rifle???

    You’ll wait for this as long as you do their ammo…fooooooorrrr ev er.

    I think AA has like 5 people working for them.

    I’d be willing to bet that HK (which was working with the U.S. military on an improved M-16 platform for several years) either won’t license the technology at all, or the cost of offsetting the license cost is prohibitive.

    Be sure to share how the call goes. I’ve e-mailed them on it with no response.

    Suhweet! ‘cept I go to AA’s website and there’s no mention of it….any chance you can provide a link? Maybe I’ll just wait ’till tomorrow morning to call them…..I hope they don’t look at me like I’m crazy 😉
