13.7” Dissipator!! Getting back in Black... out

Recommended Posts

A friend came to me and asked what kind of outlandish .300Blk I could come up with. 

Not having a pistol... and not being allowed an SBR in PRK... this was a conundrum for me, as I wanted “short” but I was having issues finding an affordable option... thus began my mission.

Fuq-it!!! I own a gawdam gun manufacturing company! I totally got this in the bag.

First, I bought a 16” Carbine barrel from Brownells to start this off. The only other options I found online were 8” and 10.5” which wouldn’t work. Finding a decent 14.5” was rare, and finding a 13.7” was near impossible (outside of a $400 Noveske). 

The only option... cut 2.3” off, re-thread, re-crown...6AFAE7E4-2B0B-48E9-B9BA-9E0651934FF6.jpeg5156D42A-ABAD-4932-8B9E-515DC1A72A4D.jpeg

Holy shiiiit my shop kicks ass... I think this feature may be getting added to my “services” options. I also have a badass 2.3” keychain coming along now. Lol. 

The next task was easy... assemble this SOB. 

I wanted an inexpensive and lightweight handguard, and I have a little passion for the “Dissipator” style rifle. My go-to is the rifle length Magpul MOE handguard... on a 13.7” barrel!!!

I had to ditch the concept of a front sight, which I was comfortable with as I haven’t used one in years.

Here she is paired next to my 7.62x39 pistol upper. All that’s missing is a custom composite shim, that I’m making, that’ll press the handguard cap into the handguard and index off the rear of the KX5.

I smell another FDE red dot in the near future.

these muzzle devices are so bestial. Obviously the KX5 is what it is, but the Krinkov on the right is identical in concept and design, but cosmetically Soviet. 

Hoping to shoot both of these ASAP.

I haven’t welded the KX5 yet. I felt there was something missing... I couldn’t shake the feeling that it was that damned front sight. 

So i dug through my old box of parts and found my old PRI railed has block. I had chopped off the front clamp YEARS ago for a previous Blackout build. It’s going to require a little more “fitting” but this is going to be amazing!!

I had to mill the fuck out of that rail to clear that fat KX5. I’m glad it wasn’t the much fatter KX3.

I got a wild hair up my ass... tapped the gas port in the faux gasblock to 10-24... blue loctite and a 1/2” bolt... that handguard cap isn’t budging

I plugged that SOB together...

This bitch is done and ready for the final weld on the blind pin.... 13.7” 300Blk (16.2” OAL)!!!

total price for upper... less than a 13.7” Noveske Barrel.

I did that tap-for-the-handguard-cap on my 45AR.  It was a blowback anyway, and I didn't want that handguard cap moving.  Good move, brother - great minds think alike.  :thumbup:

I thought I talked about it in the build thread on that thing, but I just looked at it and I never mentioned it...

 

I'll get that fucker out and get the handguards off and snatch a pic...   :thumbup:

Fuk yeah...   If I pull that small bolt outta there and the thread pitch matches yours, I'm demanding the damn DNA testing...   :lmao:

In hindsight, now - I TOTALLY fucked up an Armalite clamp-on A2 front sight base to do this - that you can't get anymore...  :laffs:  Had I KNOWN that they'd stop making it, I might have done something different.  Fuk it, it's drilled and tapped now...   and won't ever come off this gun...

That’s exactly gay I did. I found a spare hex socket bolt and thread the hole to fit. 

If you look at my pic close - you can see I stacked washers under the bolt.  My spare bolt was too long - but THAT spare bolt was the one that was going in there, gawd daymit...   :lmao:

A little Birchwood Casey flat black paint pen hooked it all up, when it was tight, and that handguard cap wasn't moving...   :laffs:

You scare me.  I'm surprised the Pants-Down Hug hasn't activated some kinda Wonder-Twin Powers, thus far, and the world implodes...    :lmao:
