My Second Build is Complete - 300 Blackout Ultimate Battle Rifle
9 Attachment(s)
Just finished my send build, a 300 Blackout. Oh my damn this is addictive!!!! I will be hand loading all of my own rounds for this one. Already have a new turret for my Lee Loadmaster topped off with a set of dies for 300 AAC. I have all of the other tools, jigs and trimmer to convert .223 brass to Blackout. Just finished this build and I have already started ordering parts for my next build.

Well here are the specs on this one:

16" Surplus Ammo H-Bar profile barrel
Stag Lower that I laser engraved the second amendment on
PSA lower parts kit
YHM extended takedown pins
Rock River safety selector
American Trigger Corporation AR-Gold Trigger
JP Enterprises silent captured spring
Rainer Arms Raptor Charging handle
Full auto BCG
YHM flip up Backup sights
Nikon p300 300BLK scope mounted on a Burris P.E.P.R. Mount
Magpul MOE grip and forward grip
Magpul UBR Rear stock.

Nice! Well done....I cannot wait to build one of these days!

Very nice. I am 6 business days into waiting for PSA to deliver a lower build kit and a lower parts kit (one pistol build and one rifle). The specs are on another thread I started.
How do you like the scope? I currently have a Vortex Strikefire on mine and haven't seen the need for magnification but my eyes are getting old.
Have you tested any subsonic ammo? I am using a bushmaster lower until I get my dedicated lower. It cycles factory subs without a problem with a semi auto BCG and carbine buffer. I was looking at the m16 BCG's but wondered if the added weight would cause problems with subsonic ammo.
Welcome to the 300 club. I haven't looked back since I bought mine!

Well I'm taking it out to shoot Saturday morning, so we'll see how it goes. The glass on the Nikon is extremely clear so I know that I will love it. I have no plans to use subsonic a in this rifle. When I get my tax stamp and build a suppressed sbr, then I'll try sub-sonics out. Right now I am loading up primarily Hornady 110gr. and 130gr. rounds. The heaviest bullet for this gun on my workbench right now is a 165gr. Sierra Game King. The load data on that round shows to be about 1650 fps. Over all I am extremely extremely pleased with the fit, feel and finish of this gun. Absolutely zero wobble between upper and lower and when locked in any position the buttstock is rock solid. The magpul ubr stock is by far my favorite... Figures it would be the most expensive out of all the ones I own!

Range report coming soon.

Very sweet, TexasG!

I am sure the person next to you at the range will be as envious as I.

Love the engraving!

Really nice build!!! Love the 2A engraving and color fill. And damn...a UBR stock...went all out :)

Looking forward to a range report and your thoughts on the JP silent captured spring.

Oh crap! I need to go and drop $1K+ for a 300blk build. And then if I go into it that far, I may as well set it up for max potential (suppression) a $400-600 can, a $200 tax stamp, optics...and now I've got a caliber that requires additional investment in reloading.

Thanks a lot, you just punched a $2500 hole in my financial well-being. Seriously though, cool gun. A 300blk setup is on my 'short list' at the moment. Mine will probably have most of the options mentioned above, and I hope to start it soon. I hope your's treats you really well.

Nice build.

msup752 06-14-2013 08:56 PM

Yep. 300 Blk will dent your wallet. My build will be finished on Monday. I'm missing a trigger and BCG. I'm using one from my 5.56. My can is finally at my local dealer so only another 8 month wait.

ZeusEcho 06-14-2013 09:34 PM

msup- what can are going with? I've got another 4-5 months wait on an AAC 762-SDN6. Hopefully I find some sub-sonic ammo by then since I don't roll my own yet.
