    Default Anybody got a stripped AR lower handy?

    I need a measurement.
    Specifically, the depth of the bolt stop spring/plunger hole. I'm pretty sure I'v got a couple that were machined incorrectly.

    I looked at a couple blue prints and both are showing .712", hopefully someone else can confirm this.

    Crap. .712 sounds about right. I've got a couple with the holes drilled .925 The plunger won't even poke it's little nose out of the hole. lol

    These were Ares 80%ers. I've got them totally machined so I'm not going to return them. Looks like I need to find a longer spring or come up with a spacer of some sort.
    I think I'm still going to contact Ares though. If both of mine are drilled wrong I'm guessing they got a whole batch of bad ones.

    Seat a short section of pin into the hole first.

    That's what I'm thinking. I'm planning to sacrifice a 5/32 drill bit to do the job. Fortunately I have plenty of them since that is the size I use for trunnion rivet holes.

    fill the hole with scrap aluminum or steel and jb weld into place or just jb weld the difference it will not be seen and jb can be anodized from what i read ( I have never done it) or use a ball point pen spring, true value hardware is your friend ( the box stores carry the springs also)
    Sprat and sprat1 are one and the same.
