    I finally finished my blackout battle rifle. I was initially planning this build for hunting but. I just love the look and versatility of a battle style build. But anyways, here she is. I'm eventually gonna throw an Aimpoint H1 on her. But the EOtech will suffice for now.

    Noveske .300blk 14.5" barrel
    Blackout flash hider.
    AAC clamp on FSB.
    MOE handguard
    Mega upper receiver
    BCM BCG
    MBUS
    EOtech 512
    Lower is a custom I had on my DDV5. Looked good on it I thought.

    And so far I love her.

    I really like it. Are you able to fit portions of your hand in front of that VFG?

    Yes. Just enough to get a thumb over style grip.

    Well done, a nice looking rifle you got there. Please keep us updated on how she shoots and give us some feedback on the 300BLK - lots of folks showing interest in that round :)

    Very nice and one of the few 300 blackout rifles here. Congrats!
    No offense, wish it could have a better rail/ handguard than that MOE handguard. ;)

    Money brother. Buy a noveske barrel, blackout flash hider, bcm bcg, etc., and see how much you've got left to drop. Lol.

    Shoots great. The vltor receiver extension seems to make a fairly substantial difference in recoil. I did have one failure to feed on the second thirty rnd mag dump she had ever shot. I haven't polished my feed ramps yet though. Hopefully that will straighten it up.

    One thing I didn't take fully into consideration is how different the price of ammo is between 5.56 and the .300 blk. I'm finding that you can't just plink around like you can with 5.56 without spending a good bit. Anyone who knows where I could find some good range rounds let me know!

    Theresb a group buy on snipers hide.com I believe is lke 45 cents a round for supersonic and 65 for subsonic

    Nice build btw. Gratz! Technically tho, it not done till its been function and reliability tested with live ammo so a range report and pictures of it in action are required!!!!!

    Oh she's been fired. 150 rnds though. What is this reliability testing you speak of? Sounds intriguing.

    Very nice rifle, broke! Actually I like the FDE MOEs, matches your other furniture nicely. Thumbs up in every way. I'm tempted to go with a Blackout upper but have to say the cost of ammo scares me.

    Shoot as many different kinds of ammo, for at least 500 rounds make sure you baby is reliable! Its the funnest part of the build!!! I'd definately run a couple hundred rounds of subsonics to make sure it cycles properly.

    You fellers are a scaren me. Well, not really.

    I have a .300 BlackOut and I don't find the cost to load all that much more than a .223/5.56.

    I am a pack rat and have been for more years than I want to say. I dug through all of my old dead brass and pulled out all of the .223/5.56 stuff with split mouths and crushed necks and the like. Checked the heads and bodies over, tossing back the undesirables. Chopped them off with a saw, sized them and trimmed to length. I have brass, same price as what it is .223/5.56 stuff. See below.

    Primers are the same.

    Bullets are not the same. But, being a tightwad, I don't go crazy. I've loaded 220 grainer, (see below) 150 (147) grain GI pulls, 150 grain nice bullets (to hunt with), some expensive 125 grain OTMs and a lot of 110 grain V-Maxs. Compared to .224 bullets, the 30 cals are a little more. Sorry, haven't found any of the other bullets.

    Powder... Different powders and amounts for both. From 16.2gr to 20.0gr of H110 (147gr to 110gr bullets) compared to my normal loadings of 25.5gr to 26.6gr of 748 for 50gr and 55gr .224 bullets.

    So the only big change is the price of the bullets. Powder is actually less cost per load.

    Course, I load all of my own and if my desire is to just go bang a lot, well a .22RF does that and I don't.

    The 220gr slugs (right photo) went into an old cedar log and I was able to dig them out.

    I like the .300 BlackOut. It doesn't replace my 308/7.62 or .223/5.56. They all have a place and fill them well.
