Thought I would share the finished product. Original DPMS upper, lower, barrel, and BCG...for now. (Waiting on a Faxon or Aero BCG to get back in stock.) LaRue MBT-2S flat bow trigger, Aero LP gas block, Aero complete recoil system...(couldn't find the Armalite available). Guntec 15" forend and a Lantac Dragon ASR brake. Vortex Strike Eagle 1x6 I cannibalized off of another rifle. Eventually this rifle will get the 1x8. Took it out and ran it this morning for the first time. Put 60 rounds through it and it functioned beautifully. Big fan of this brake. Muzzle rise is so negligible I could do rapid pairs, and failure drills like it was an M4. Did a brass check and it wouldn't go back into battery due to not having forward assist serrations on the carrier. Other than that I'm pretty happy with it. Thanks a lot for the recommendations and guidance during this build!

Thanks 98Z5V good alignment and unimpeded airflow. Appreciate it!

Going to check it now. Thank you.

Gents, Quick question. The build is coming along nicely and I've sourced all parts with the exception of the BCG and the Armalite complete recoil system. However I ran into something unusual and wanted some advice before proceeding. The dimpled recesses on the DPMS barrel are closer together then provisions for the two Allen screws holes on the Aero LP gas block I bought. Is this an issue or cause for concern in your opinion? I've seen AR barrels come with no dimples and the Allen screw are torqued flat against the barrel. With the gas block in place and aligned I've got good air flow through the gas block port. Plan on using blue threadlock on the screws. Thanks.

My focus is on Wyoming or Idaho as well. I'm tired of the desert and Yuma is getting crowded...and Border issues. We live across the street from my aging in-laws and that is the denominating factor in why I haven't headed North yet. I understand. My parents are still in MD, but luckily I have a very capable sister who helps on that end.

I was from Harford and Cecil County up on the P.A. Border. You in central MD?

Yeah you're right. New to this forum format. P.G, or Montgomery County probably. Definitely the armpit.

Haha...very true. On New Years 2006 I had four rescues in less than 24 hours all around Gordon's Well. My backyard opens to the desert and the kids and I have quads too.

Where abouts in Maryland?

No dunes. I did many medevacs out there in my time with Yuma SAR. Too many drunks and Californians...just not my thing. I've got YZ250F that I do a lot of trail riding with out in the Barry Goldwater range and down to the border, and all over the Gila mountains. I prefer to go where it's less traveled.

Originally from Maryland myself, but transplanted to Arizona about eight years ago. Thank you!

Thank you! Great info.

I'm glad I joined this forum. Thanks to all of you for your insightful and well written responses and recommendations. This kind of information is what I was seeking. I have built many AR-15's, M-4 clone, 14.5 BCM race gun, 18" Yankee Hill DMR...etc. Even own a Sig 716 and a purpose built Remington 700 that I finally hit 18" x 20" steel at 1,100 yds last year with 175g Prime ammo. So pretty diverse collection of purposely built weapons. I had forgotten about the LaRue trigger even though I put one in a buddy's build last year and really liked it. But again this is my first M5, AR-10 build and I wanted to get it right. I wanted to build it reasonably lightweight with the purpose of filling in the gap between the terminal performance of the 5.56 on hard targets and the precision shooting of the bolt guns, while CQB capable and still having decent accuracy out to about 600 yds with 147g surplus ammo. Going to order the Armalite buffer kit and the LaRue trigger. The stock will be collapsible. I'll be coming back to talk optics after I get done. Thanks again. Also wanted to add I got this from Sportsmans Guide about three years ago. Looked it up today and I paid $617 for it. Couldn't let that pass

I was considering the Geissele SSA but I'll look into the LaRue. Ive been a long time customer of their products. Do you happen to have a link for the Armalite complete recoil system? I did a quick search and found a plethora of different items. Secondly is it compatible with the DPMS platform? (I'm sure it is or you wouldn't have recommended it) I am just not an expert on the nuances of Armalite v DPMS.

Thanks Edgecrusher! That was the answer I was looking for. I assumed it was in the LR .308 platform but didn't want to go into poverty ordering the wrong parts. So far I've only ordered the LaRue Polymer Combo package (furniture) in UDE color. Waiting on an Aero Nickel BCG to become available...any preference on carriers? I was dumbfounded to see that the DPMS didn't even have the forward assist grooves.

I have searched everywhere and cannot find if the Oracle is considered a Gen1 or Gen2 DPMS platform. I have one that has been a safe queen for years and am ready to do a conversion on it using only the original upper , lower, and barrel. But I understand that the gen 2 has a shorter BCG then the gen 1's. So again which generation is the oracle considered. I understand the difference between high and low profile and can easily identify that, but finding the correct BCG has become difficult without knowing the detailed specs of the rifle.. Any help is greatly appreciated.
