    Default 5.45 EXP/TEC Tactical AR pistol

    thought i would share this here since you guys like most of my "custom" work...

    this is one of the new EXP pistols that Pryotex is selling thru TEC Tactical..

    but naturally i couldnt leave it alone. ;D

    so instead of the 5.56 that i loathe... ive converted it over to 5.45x39 which ive got lots of!

    what had to be done?

    bolt head

    barrel

    lots of tinkering.

    so lets start at the bolt head... you can buy a bolt head or you can convert a 5.56 over... works either way!

    barrel: these are not real easy to come by right now.. so you can get one & cut it down... or pay a lot for a short one.. i opted for a $130 regular old barrel then i cut it off at 8" & had a buddy thread it at work. then it was about turning it down where it needed to be on my mini lathe (7x10) & putting in a gas port hole.

    with some careful measuring and a little math i figured out the hole size which was NOT a standard size for this barrel length & operating system.

    stuffed it all together 3 times, because i kept putting it together "regular style" instead of how this particular pistol goes from Extar...

    then ad some surplus ammo & its test time!

    That's pretty sweet. Glad you got it running smooth.

    yeah just had to play with the gas port a little bit...

    with this small spring set up, you only want as much gas as it needs.. no extra.. the 5.56 gas port hole was super duper small... this 5.45 hole was just a shade larger when it landed just right.

    i did run Wolf commercial 5.45 & a mix of the 5.45 surplus stuff thru it.. made no difference at all.

    Sean...........if enough people express interest..........I'd be into making a run of barrels to your spec.....would you let me borrow the .223 take off to get a solid model generated so we can see what it'll take to run them.....?

    King Armory designed a 28rd high-reliability AR magazine for the 5.45x39 round.
    This is a full auto test of the mag prototype.
