CrashOverRide.308

What do you mean If I don't need a gas block if everything in the system is in good order?

Jtallen, Shepp, Guru! I was reading up on the gas tube and "adjusting" it. How often should you adjust for the right ammo? When do you adjust? Is there a 1 time adjustment for different grain ammo? Or is it just a constant adjust for different types of adjustment? I've seen FringeSniper on youtube who adjusts his to 4 clicks (Hex screw) then I saw Hickok45 adjust the ar10 back and forth between 2 types of ammo. 3 clicks for brazilian .308 and 2 clicks for federal? Sorry for all the questions that has been ask 1000x's.

Thats great! Thats the BCG Im looking to go for. Now for the barrel to match it up. Thinking about a 16" but I'm going to go the 18" route for long shooting/hunting. Im sure I will suffice with the 16" for a few 100-200 yards but a 1 time buy for an 18" will do great. Thank you for your input and experience Guru.

Nice.. Thanks a bunch man. Will be looking into this vid for reference. What do you guys think of this BCG in a matrix? Jtallen, Shepp? http://www.aimsurplus.com/product.aspx?item=XAIMBCG308NIBBDG&name=AIM+.308%2f7.62x51+BDG+NiB+Bolt+Carrier+Group&search=bolt+carrier+group Any ideas where I can find something in stock for an 18' DPMS pattern barrel? A lot of the sites Ive been on are sold out or out of stock

Trying the best I can to go with a budget build. May I ask JT. What kind of BCG and barrell did you go with your Matrix?

I see. Im a noob to all these rifle components. Doing as much research as I can. I've seen others how to install all the lower receiver components and upper receiver components. But there isn't any installation of the BCG installed? How is this done may I ask?

Chris and Lori mentioned the ones they have are DPMS. It requires a DPMS castle nut only. Here's another one. About the ejection/dust cover, Forward assist and Charging handle. Are they all pretty universal for the .308? Or is there a specific one made for different brand rifles? Ive tried googling. But nothing really comes up about it.

I see. They don't make it easy on you. But hey. Its the point of building. Now, Please forgive me. But the seller that I bought from Central Florida Firearms stated that it cannot be mixed and match. If I decide to go with DPMS. It has to be DPMS Barrel and BCG vice versa with Armalite. (Both receivers are made by Matrix Aerospace Blems. $199.99) I've been looking at DPMS. Now I've been on DPMS website but Im not sure if its just "down" or they've decided not to update it ever. So its hard to find a DPMS barrel parts. I was on aimsurplus and looked up DPMS they have tons that says (DPMS STYLE) Should I go ahead and be confident and buy it? same with the BCG down the road. Same with the handrail/guard. Im just super confused by these "DPMS Style" Clearly there is an actual DPMS website but its just pointless going on there for anything. any insight on this would be GREAT.

awesome. Thank you. Lots of questions. If I purchased and BCG wouldnt it already be spaced?

Awesome. Thank you everyone for your input. Lots to look up on. Just want to be prepped. Also. I see a lot of old posts on here.I'm assuming this forum isn't as active? I read posts that are years ago sometimes. Not all.

I meant the gas tube? But anyway. How much of headspace is needed?

aright.Thank you sir

I am entirely new to the AR system. I'm going to start building an AR10. So far I have ordered both the Matrix Aerospace upper and lower combos (stripped) along with a lower parts kit. I'm only worried about the tubing and the barrel. My concerns are: Do I need to do anything special to the tubing and the barrel? Is it only required by a gunsmith? I have heard its more complicated with the barrel, because you have to make sure everything lines up and you have to "gap" it correctly. If not all hell will break lose? Is this true? I thought it would just be a plug and play once everything required is installed. What do I need to look out for? What should I expect? What tools do I need? I'm doing some reading. But there isn't much to go off of. Experience builders. I am in need of your expertise. Thanks in advance. If i've posted this in the wrong section I do apologize. -Alaska
