808chx.irradicator Posted July 6, 2021 Report Share Posted July 6, 2021 Hi everyone, let me first say sorry for not reading 'every' post in this section that might help me but I just don't have the time. I'm in the process of building my first large frame AR and am just seeking some advice/suggestions. I'll start with the parts on hand stuff in my best Garandthumb voice "from tip to butt": precision armament hypertrap muzzle break criterion 22" DPMS pattern hvy. hybrid barrel I do have a Superlative Arms adjustable gas block, clamp style, but I'm not sold on using it yet rifle length gas tube from Aero Precision, but I wanted the Rosco one Aero Precision Enhanced upper/M5 lower, both stripped (I REALLY like their enhanced uppers) Aero Precision Enhanced rail, 15" Radian charging handle Aero Precision LPK minus the fcg because I haven't decided on a trigger yet, and I plan on using Radians ambi selector as soon as I get one Ergo tactical deluxe grip Standart A2 rifle lenth buffer tube both a Magpul PRS and a LuthAR mba1 What's needed so far is the BCG, trigger, maybe a non-adjustable gas block(which I prefer), and to finish off the gas system with a buffer and spring. Let me just state that this build for me is about reaching out and touching someone at distance. I'm really trying to see how far this 308 will go accurately and am not worried about carrying it for time or maneuverability, that's a whole different build for the future. So to my questions, any suggestions on a BCG to match the intent of this build? I know times are hard and it might take a while, but I can wait. Also, I've always wanted to try JP's silent capture system, anyone have experience with that in this form? If not that, suggestions on finishing up my gas system? Thanks in advance for any input, Mik Quote Link to comment Share on other sites More sharing options...

The restrictive side of the block worked fine like any other restrictive type block. If you are not going to run a suppressor then you don't really need the adjustable block. Fulton Armory has a real nice BCG with high pressure bolt for a good bit less than JP. Quote Link to comment Share on other sites More sharing options...

Try the gas tube that you have first, and make sure it reaches the center of the cam pin cutout in the upper receiver. If it's short, you'll need the Armalite AR-10 gas tube equivalent. Trigger, start out with a LaRue MBT-2S. It's cheap, and it's made from S7 tool steel, and it's great-priced. Work with that for now, and I'll bet you never feel the need to change it out. Leave the recoil system for last. When you DO add the recoil system, use basic parts first, and not fancy shiit like silent-captured this-n-that. You're running a rifle recoil system. Use a .308AR rifle buffer (5.200" long and 5.4oz), and just use an Armalite EA1095 recoil spring. Make a functioning gun, and when it runs and it's broken in - start changing out for some of the fancy, Race Gun parts. My $0.02 on the whole affair.

It's gonna be Armalite or DPMS-based - and those are AR15 gas tubes, with a different bend than .308AR-based height-over-bore. Something to think about when recommending parts. Again, just my $0.02 on the whole affair. You make a functioning gun, first, with basic parts. You spice it up later, with all the fancy shiit.

Thirstydg323 Posted July 7, 2021 Report Share Posted July 7, 2021 They will make the tube any size you want,all you have to do is call them. They carry up to a plus 2 I've had them make a few custom ones for me. I'm sure you know how that goes Quote Link to comment Share on other sites More sharing options...

The LaRue trigger and Armalite spring kit 'should' be arriving soon, tracking's kinda sketchy but they're on the way. Your earlier comment about the gas tube and hob, so far it looks like the Aero tube will work but we'll see. I'm looking for a non-adjustable gas block and will probably go with the Fulton bcg recommended by jtallen83. My next post I'll take pics of all the parts and the build process.
