    I may just avoid them in the scar heavy for now. Even if the screws don't migrate, I've also heard of receivers cracking. There is obviously something going on with the heavier bolt carrier group and the 308 round in the scar system with an aluminum buttstock plate that is causing undue stress on parts. Heck who knows what it may do to the even more expensive optic sitting on top of it.

    99.9% don't have problems. If anything tune the gas down a little bit with a smaller gas jet. Should be fine.

    I'm in the same boat with you. I too have a scar heavy and wanted a KDG stock.

    After reading a number of metal hinge plate threads I've decided to pass on any stock with a metal hinge.

    I bought this gun based on its reliability and durability. I have no interest in mods that degrade either of those two things even a minuscule amount.

    Personally I think the best policy is to own a second fn stock to have on hand if the original breaks in anyway. I also never open the stock with out fully depressing the button when locking it in place.

    It's a great gun, the hinge plate is its weak point. Putting on an aluminum one actually causes worse problems long run. I'm in no way trying to jack up my receiver. I'd rather the stock be sacrificial.

    If they would put some sort of insert or shock buffering or better yet make them out of plastic like the OEM stock this would be a non-issue.

    Reminds me of that company that made alloy Glock lowers(CCFA?) only to find that Glocks will beat themselves to death with anything other than a polymer frame. People who built some incredible Glocks on those alloy lowers had to use a special frame buffer that would get chewed up in a couple thousand rounds to make them reliable.

    I am just waiting for MGW to get some more SCAR stock assemblies in house so I can have a spare. Not super worried about it but I have gotten so spoiled playing Barbie Dressup with my ARs with new stocks, rails, furniture being stuck with the world's ugliest stock on my SCAR took some getting used to.

    What didn't take getting used to was a 308 gas gun that didn't need to be babied like my AR10s. I have never had a 308 pattern AR run right from my original SR25 with the white polymer buffer to my last Noveske/Fulton/Etc build. My SCAR has 5,000rds down the pipe without a single malfunction and the maintenance is a breeze! I'll gladly handle the stock hinge thing if it comes up as a tradeoff.

    Is there a preference as to which extended rail is best ? Is there a model currently being used in military applications?

    Are the SCAR stocks available for sale and what price range?

    I know several team guys bought Handl AFR's but they were 3-4 at a time.

    I just bought a used SCAR 17 with Stryker industries sr25 pattern lower and VLTOR stock adapter. Will I run into the issue with screws/backing out, etc...people are mentioning earlier in the thread when using a metal hinge?
    Any other tips/what to look for?

    Thanks.

    andy,

    The Vltor sotck adaptor is the best of the solid hinge plates. Handl Defense made a solid hinge plate that allowed for the OEM boot and a yet to be release stock. After a discussion with the guys in Herstal it was discontinued. The polymer hinge acts in a way to reduce pressure to the upper receiver. Those two screws on each side are the canaries in the coal mine. Now because of the alloy lower there will be some added rigidity and a bit of pressure taken off of those screws in the long axis. A good explanation is here https://www.handldefense.com/2017/04...-for-the-scar/ the striker lower was directly rev-engineered from the handl and will have some but not all of the same properties.

    OEM stocks and hinges are not the prettiest but they are the most effective. FN says they are coming out with a set of options for the back end of the SCAR ... I would wait to see what they offer
