AR15 300 Blackout Pistol Project

[cundiff5535]

I started this little project about a year ago... picking up parts here and there as I could. I own several 223 rifles in every configuration... I did not have a pistol or 300 black out though. So, I killed two birds with one stone! Just finished her up tonight, so I hope to go tune her and sight her in over the next week.


**Im not a cold weather guy, so it may not be until later this spring

Because I have my fair share of AR riles, I was able to take a lot of the stuff I liked from my previous experience and throw it into one nice little pistol. As you will see, I am a real sucker for Seekins parts, but IMO they are just so well made and some of the best out there. I currently own at least 3 rifles build with all Seekins parts (besides the barrels, I typically buy Krieger or Compass Lake).


Here is the breakdown of parts for this little guy!


Seekins Billet SP Receiver Set
Seekins 10" MCSR Keymod Rail
Seekins Micro T-1 Mount
Seekins 8.5" 300 Blackout Barrel
Seekins Full Auto BCG
Seekins Adjustable Gas Block
Hera Arms Linear Comp
KAC Pistol Buffer Tube
Sig Brace
Hypertouch 24C Flat Trigger
LaRue Apeg Grip
BadAss Ambi Safety
Vortex Sparc II Optic

That is flippin sweet!

What's your estimate on cost for everything? I've been toying with the idea of building a 300 blackout.

 

[milton]

That is very nice. I'm a fan of seekins stuff also.

Why do you have the optic sitting so high?

 

[cundiff5535]

In all honesty, because a shop I work in is a dealer with Seekins, and because it parted it together over a year or so. Without the optic, I think I have right around $1100 in this thing. Dont quote me on it... could be way off, lol

 

[cundiff5535]

Why do you have the optic sitting so high?

Not sure what you mean... thats the lowest you can put it on the mount, and its right at eye level when you bring the firearm up... literally at 1/3 co witness

 

[throttletony]

looks great

That looks great. Can't wait to here how she shoots. I'm in the end-game of my own .300 Blackout pistol project but mine is a budget build and can't compare to yours in terms of the quality of the components.

Looks nice, really like the upper and lower set.

Why do you have the optic sitting so high?

Its right in line with your eye when you shoulder it.

 

[cundiff5535]

Its right in line with your eye when you shoulder it.

No... cant shoulder this pistol...

That is a gorgeous build. I have been tossing around the idea of building something similar but am to cheap to make something that pretty.

Nice looking 300. Helped a friend build his with the Thordsen kit...Thordsen Customs | Innovations for the Black Rifle Enthusiast | Thordsen Customs

Loading 125gr TMKs.

No... cant shoulder this pistol...

LOL. Something like that. I can't say mine hasn't completely accidentally bumped into my shoulder on occasion while shooting it.

I have the Sig Brace on one of my pistols and the Shockwave Blade. IMO, the Blade is a better option since you "can't shoulder it" and the Blade is a LOT lighter. They're fairly inexpensive. I'd recommend giving one a try.

Edit: BTW, that's a beautiful weapon. Great build. I hope it shoots as good as it looks.

Form 1 with CLEO approval sent out, reciever engraved... This will soon have a stock on the end

 

[BIGE7.62]

Sweet build . What trigger are you using ?

 

[cundiff5535]

It's a hyper touch 24c... Very, very nice trigger.

 

[BIGE7.62]

It's a hyper touch 24c... Very, very nice trigger.

Okay , Thanks
