    Default Ar shorty build

    I've never done a blow-by-blow thread on a build, but I thought why not. I just received my bbl today so here goes. 16" m4 ar stoner non crome from midway, cut to 10.3. Now i will see a machinist friend to turn the muzzle down for threading. I have a U S Auto "Special Forces" comemrative complete lower on its way.

    Be sure to get the NFA paperwork in hand if you are assembling an SBR.

    there is a bloody chart somewhere that has the correct gas port size for a 10.25"

    generally a shorty will need a slightly bigger port--that is less the port it has a bit on the big side to start with. then you might all ready be close.

    the colt chart says .093" for a 10.24" --can't find the LMT chart--it is around here somewhere--

    i figure that is pretty close.

    if you have a removable gas block i would just give it a try first and see if it will run as is. a pin on is such a PITA to put on and take off i would drill it to the colt size then try it--but hey that is just me and i am lazy! LOL!

    I'm thinking doing it up like one of these in the pic, kinda to pay homage to our bug eater guys in all the branches of service, but I like the idea of a mid-length free float railed hand guard with fold down sights. This may be my last "evil gun" build, depending on what the goons in washington do, so I thought why not go all out on it and do it however I like no matter the cost.

    SMG still has some of those cheap quad-rail free floaters --only thing about them if you go under the hood with the mini-gas block you'll have to extensively re-work the things to get it to work.

    those GIs look like they got bolt on rails --the kind you can put on sort of like the GI hand-guards. that way you don't have to deal with the fiddely FSB pins.

    now i built two rifles with the lo-profile gas blocks so their free-float quad rail to nearly the muzzle.

    i have to say i like the over the gas block installs better.

    but they all work well it is really just whatever you prefer.

    Thats where I'm stuck. I dont know if I want the as issued CQBR look or a handguard over gas block that goes nearly to the muzzle. Like this HK 416 on the bottom. It also has the gas piston set up and I've been toying with that idea as well.

    if your in the long green stimulus check side of things take a look at that 'VOLTOR"??

    kit --it has an upper with built in quad rail free floater one piece--

    very pricey-- like $500+ for just the upper--it do come with a special wrench and barrel nut--no charge--LOL!

    hell you even consider one of those LMT piston jobs? their like $1K for a upper but i hear they run beautifully ---

    i want to buy one of them myself--but i got to cash in a few lotto tickets first--
