    That's the blem upper , Blem lower/w parts kit and blem BCG I have a 5.56 barrel I got from Midway but I figured I can afford to shoot 5.45 so now was the time to use the barrel. I will be opening the bolt shortly. Furniture was from some trades etc Gas block is clamp on rail type and I have some imitation magpul BUIS to go with a red dot scope.

    I can't remember right off hand what they are (5/64" or 3/32" perhaps?) but it is a common size. I can never seen to find them the right length though and just get the longer ones and make two out of them. Take your gas tube with and check for fit. I have used cotter pins in a pinch or for fitting parts ect.

    Do what you want ,,,,but I myself would never use hardware store anything on a firearm,,,,period, unless you're screwing on a stock or something. Next time you go, look at the box's there screws ect are in,,,,,made in China,,,

    Temper would be suspect with any of that hardware you'll get at a regular hardware store IMO. I've bought grade 8 stuff before there to use on a marine application and when I went to torque it down it snapped well before even getting close to the torque spec., and they were "grade 8", supposedly. NO WAY IN HELL should a 3/8' grade 8 bolt snap at a 35 ft lb torque setting!!!! And NO,,, it wasn't the torque wrench either, it's a Snap-On wrench that's very accurate, not some 14.99 special from wally world. Not a biggie there and it just took some time to get out the broken piece. On a gun though,,you just might get the failure when you shoot it!!!! NOT GOOD!!!!! I've used some roll pins from there before for some other non-gun projects around the house and they all failed miserably, and they were used in a area where there was little pressure on them, so myself I just don't trust that cheap hardware at all.

    We had a guy around here a year or two ago that did a AK screw build with Aubuchon Hardware Store screws,supposedly grade 8 oval head allen screws,, and on the 3rd shot the trunnion ,barrel and everything out front,, ended up laying on the ground 10 feet in front of him!!! He got some injuries out of the deal too,,how bad I don't know? But he was in the hospital for a few days and when I saw him,he had bandages on his nose and 2 very black eyes and a bunch of stitch's. So do what you want to. BUT,,,,,,,,just saying!!!

    You don't have a gun shop local where they might just have a selection of hardware?? Worst case get one of the "spring and pin kits" just to be safe. That would be my call, but that's just me,,,,I'm a pussy and just don't relish the idea of spitting out gun parts myself. Just me. Hell probably one of the members here could even fix ya up with a spare if you have some buds here.

    I sure as Hell wouldn't use hardware store , hardware though!!

    the gas tube roll pin is just a standard roll pin like any hardware store-farm supply/hardware store sells.

    i don't recall the size --but i have seen many replaced with no issue. the only thing is you may have to cut the hardware store ones to length as they probably won;'t have the correct length.

    any roll pin can be replaced with hardware store ones of the same size. their is absolutely nothing special or military grade about them.

    the only things about roll-pins i have seen is any pin that is installed and removed several times loses its tension. in that case a new hardware store pin is better than a USGI pin that has been installed and removed a dozen times.

    the USGI pins are made from hardware store stock-- it is the same thing.


    TWA is correct about the bolts -- never use hardware store bolts on anything that has a grade requirement--

    remember jon denver?

    that is a no-no--

    i would send you one if i got a spare-- only thing is i am so bad about losing those little flea sized things--LOL

    a rule of thumb for the roll-pins is as long as they got tension their still good. when they start going in too easy--toss um.

    Thanks 2nd

    has any one opened up a 5.56 bolt to 5.45, from all I have read its the rim size plus a 100th and the extractor rounded slightly any one with some experience with this can you chime in and give me some pointers.

    Yes, several. Chuck up the bolt and center it, use a carbide bit/boring bar and don't remove any material from the bolt face. You will want to touch up the bevel a bit since you removed some of it. You can also round off the corners of the extractor slightly if they are causing problems.
