  1. Put on some canted iron sights on there in case your scope fails. Otherwise it is not a battle rifle it is a range rifle. Also quit being a dumbass about your tool doors in your stock. Put them back on you you can put tools such as a wrench for an adjustable gas block or a dirt brush. That or quit being a CoD fag and calling it a battle rifle

  2. one more thing i forgot to mention months ago.  The integrated trigger guard is a disaster waiting to happen, what if lets say the rifle drops on an angle where the full weight of it hits the trigger guard and it snaps or bends or breaks?  having a trigger guard that's detachable is better for those reasons if so it did break you can go ahead and use the original flat trigger guard until you can order a new one.  Integrated has fewer lines which makes a gun look dull…

  3. The only 2 things I see I would change. Is the scope mount. You want a very solid grip on it. That one ,looks like it will give you trouble. Not enough foot print. The other thing is ,put off set iron pop up sights. Scope is nice but iron is a must.
       I just got done building a AR10. Mostly out of Palmetto armory

  4. foreals you messed up on that barrel son, you should have used a stainless, and that muzzle break, too much noise, all black, you needed carbon fiber hand rails, need teflon upper reciever, you dont need a nickle baron bolt carrior group, get one thats just has a capenter bolt, for reliability, your optics suck, you need one of those 2 k nikon sights, you put on garbage sights and claim to be a competition shooter.  I know im just hating on your nicely built ar 10, its really nice btw.  build ar 10 build it right, my friend has one all troyed out, may he spent 3k and i think its just average price on it too.  YOU PLAN TO RELOAD YOU OWN AMMO BUT DONT HAVE FORWARD ASSIST? ARE YOU INSANE please please… what if you put in the wrong mixture of propellant and the carrier doesnt go back all the way leaving a  catagory fail type malfuntion.  Failing being a dumbass bitch please, and yups i was just kidding

  5. great vid. Just built my own and having some short stroking issues. All premium components, so very frustrated. Shoots like a dream for about 30-40 rounds then the issue starts to happen. Also, very very important to plug up that FA. A buddy of mine used the FA and dented my JP BCG. 

  6. Thanks for the video.  I'm currently building and LR-308 with similar components.  Namely the LMOS BCG, adjustable gas block, and JP Silent Captured Spring.  Q1: how many rounds have you fired? Do you feel like it's "broken in"? Q2: can you approximate how much of the gas you have tuned from WOT? Q3: did you experience any tuning challenges or cycling issues since initial setup? Q4: which spring in the SCS system are you using?  Q5: do you feel the extra expense was justified?  Thanks.

  7. Great review. I bought a Hogan .308 lower that I want to build out. I might take some of ur specs.
    Any other advice. That barrel looks badass . What can I expect to pay for it
