    Parts kit

    This kit is very handy to have, at an unbeatable price. I getting one for each of my rifles. I would recommend this for anyone with an AR15.

    Parts kit came complete as advertised, I haven't used it yet but I'm doing my 1st AR build and I'm sure it'll come in handy as I always loose stuff.

    Must have for all you AR fans out there.

    You ever lose a part or brake something while shooting or out in the field? I really sucks. Yes... Those kits are cheap and you can keep them in your bag. A must for everybody with ARs. Get them and buy a few of them.

    I haven't YET but it happens in the worst place and the worst time. Without the part to replace the one you lost, you would have an expensive stick. Spend the few bucks and keep them in your field kit.

    Necessary item

    Don't build a AR without this kit. I didn't need it in the first on but lost a front pivot detent. On the next one I put together.
    Was happy I had it.

    This kit is a godsend. After losing both takedown pin detents across the room (anyone who has built an AR15 knows EXACTLY how that happens), I purchased this kit. Luckily, I was able to get the detent in with the THIRD pin. Now I have extra parts - for the NEXT time it happens!

    Prefect Kit

    Posted by Richard Rougeaux on 4th Aug 2017

    I recently purchased a Lost Oarts & Repair kit from Stag to finish my build. This will be my second time purchasing the kit because you never know when you will need a spring or indent for a new AR project or repairing your favorite toy. Stag offers everything I need in a nice kit without the hassles of having to buy a bulk amount. Thanks again to you all at STAG ARMS.
