    My profile pic is a 10.5 inch barrel SBR with the KAK flashcan.

    Is that vertical grip ok on the pistol? I thought only angled grips were ok, unless you SBR it

    See my comment at the bottom of that post in parenthesis.

    If the OAL > 26" with the brace fully collapsed (if applicable) and no muzzle device, adding a vertical forward grip does not make it an AOW.

    Ahh ok thanks, just skimmed through this reading: Can you add a vertical fore-grip to an AR pistol?

    I'm learning everyday :)

    Looks like everyone with AR pistols in this thread went 5.56....Anyone build one in 300 Blackout?

    I was wondering if the MA Loaders for the .223/5.56 work with 300 Blackout. I'd be interested in a build if that's the case.

    I don't see why it wouldn't. Same diameter case. Similar OAL.

    This. There's no reason why they wouldn't work. .300 Blk is just a .223 case necked up to take the .30 cal bullet.

    As to not doing one for .300 blk, well, I don't have anything else that eats it, so for the first one I kept it simple. Theoretically you could do any caliber you want, you'd just need to change out the fixed magazine for a caliber appropriate one. Something like a Lancer with a single stack follower would work great for large bore rounds (.458 SOCOM/.450 Bushmaster/.50 Beowulf), though you loose the ability to use the side loaders for any caliber that doesn't use .223 as a parent cartridge. Top loading isn't that bad, and really only slightly more annoying than loading magazines the normal way without a speed loader.

    Might do a .300blk one day, but right now I can't really afford to start stockpiling another caliber.

    I almost went 300blk. In the end, I decided to stick with 5.56. There is some decent ammo for it and I figured that was AOK. With the short bbl, you still get the terminal effects of the 5.56 at close range. This isn't a 50yd gun. It's probably not a 20yd gun. My house is only 40-ish feet at the longest point. In the back yard, I might get 100-120 feet from woods-to-woods. That would be extreme for this firearm.

    I was on the fence too...at first I was leaning 5.56, as I wanted to say with a caliber I already had. BUT - The trade-offs seemed too great when going with a 7.5" barrel. Huge velocity loss, increase in noise, and I didn't want to go with a 10.5" barrel either. By the time you add a FH/comp then its close to rifle length.

    Sooooo 7.5" 300blk it is. After pouring over data/videos/interweb opinions, the 300 blk has some interesting offerings in bullet weights and performance.

    Went with:
    Karri's Guns 300 Blackout 7.5" upper w/flash can & 9" MLOK rail w/hand stop
    Karri's Guns BCG & Ambi CH
    KAK Shockwave Blade & pistol buffer tube kit
    AR Stoner LPK (w/WMD Guns NiB trigger)
    BCM Mod3 pistol grip (on the way)
    Fixed Mag Lower

    Need to decide on optic, thinking 1-4x. Irons for now.
    Also want to do a side-folder.

    The nice thing is you can always get another upper. I might try it some day. I went the 10.5 route. Agree that 5.56 is not 7.5 worthy.

    Do you people have any idea how much money NES costs me. Damn you people!! Lol

    Take a look at the performance/gel tests of the 194 grain Lehigh Defense 300 Blackout offerings. Looks like a good HD option.

    Yeah, just swapping uppers is easy enough. However, I've got a pinned/welded 14.5 - so a 10.5 really doesn't interest me too much. At they end of the day, they wouldn't be all that much different.

    Now - looking at 458 SOCOM or 450 Bushmaster, that may be worthy of another build. IIRC there are 30rd mag bodies with a specific follower for the big bore rounds. Something like 10rds of 458 fits in a 30rd mag body. Just imagine how much of a thumper a 458 pistol would be!

    Love 300BLK, wish we could have suppressors in MA though. If you keep loaded mags around make sure you label the caliber on them!

    Tromix Restricted State, Compliant Magazines - Tromix Lead Delivery Systems

    Pin one of those. .458 SOCOM is a fun round, but it does get expensive to shoot. Kicks like a mule, too. Tony also sells completed 8" uppers for .458 SOCOM, 12" uppers for .450 Bushmaster, and 10.5" .375 SOCOM and .50 Beowulf uppers. I've got a 16" Tromix barrel for my .458 SOCOM straight pull bolt action AR and it's more accurate than I am.

    Truthfully, if you want to go the shortie big bore route, I would get a tax stamp on a rifle lower. You're gonna want a good buttstock to help absorb that recoil. Also make sure you get a big bore style upper receiver. A standard .223/5.56 upper has to have the ejection port opened up slightly to allow reliable ejection of the larger cases, but a .450/.458/.50 upper has the ejection port already milled out a little more.


    I disagree--7.5" is perfectly fine with 5.56. Mine groups beautifully at 50 yards, and the only reason I haven't stretched it out to 100 yet is a.) laziness and b.) lack of time to get back to the range. It's an eminently workable CQB upper. Ideal for home defense, though with all carry and HD guns I would make sure to put a couple hundred rounds of your ammo of choice through it to ensure reliability and to know how it performs.

    That said, I also went with a 10.5" that will eventually go on my SBR when I get the stamp back.

    You're very welcome. Both Fixed mag lowers are JC lowers, very happy with them. Thank you for a quality product. Any thoughts of making AR10's?

    Maybe in the future, as of right now we are overwhelmed with making the standard caliber platform. We only have one CNC machine unfortunately.
