  1. Okay, I received my Armalite spring last night. Installed it and managed to get out to the range after work. Wow!!! What a difference. Zero issues and I ran everything thru it . . . cheap 149gr 7.62x51 rounds, Hornady .308 150gr Whitetail, .308 165gr whitetail, and PPU Rifle Line 180gr rounds. I have to say, the machine ran flawlessly. I only had about an hour at the range, but after zeroing my scope I was extremely happy with the accuracy and consistency. At 100 yards, I was able to keep 5 round groups within the same 1-1.5 inch area. Hopefully, I can tighten that up with some more practice. I’m sure that’s a cake-walk for most of you experienced folks, but I’m thrilled. Thanks again everyone for your advice and experience, particularly 98Z5V for his item by item recommendations!
  2. More progress. Soaked the BCG IN Mobile One for approximately 30hrs and it’s been hanging since last night. After work today, I’ll wipe the bolt face and reinstall in the rifle. I’ll get that Armalite spring in the mail either today or tomorrow. I hope to install the spring upon receipt and get myself to the range soon after. If the Range-Gods are smiling, I’ll have decent weather and the combination of “fixes” (buffer length, gas port size, spring replacement, and BCG soak) will have resolved my rifle issues. If not, I know enough to take lots of pics and should be able to describe any malfunctions in better detail. Thanks again for the benefit of the community’s knowledge and experience, I’ll check back soon and keep you updated on my progress.
  3. So, fully submerge the BCG in oil? I’ll find something that’ll work, but is there a specific grade viscosity? Shooterrex recommended MobileOne, so I’m assuming that synthetic oil is what we’re talking about here. I’ll admit that, at first, I thought Shooterrex simply meant “lube the crap out of the BCG”, my bad. Looks like I’m waiting until Tuesday, 1/24, before I get my new Armalite spring. I’ll give the BCG a soaking, and continue my research into a scope in the meantime. I moved the mediocre Bushnell BannerII 4-12x 40mm from my 556 over to the 308 for the moment, but I’m eyeballing the Vortex Crossfire II 6-24x 50mm as the permanent glass for the 308. I’d like to stay on a $300 budget, and funds are tight after building the gun itself. The 308 will primarily be used at the range and some friends are trying to talk me into taking up deer hunting this year, so I’d like a scope that lends itself to that purpose. I know there are plenty of great options out there if you’ve got deep pockets, but those options rapidly decrease when pockets are shallow. I know I’m putting the cart before the horse by thinking optics before I’ve got all the bugs worked out, but research never hurts. Does anyone have any suggestions?
  4. Well, Hell….. I dunno how I managed to post a duplicate of my last post?!?! Well, anyhow, just a little status update for those of you kind enough to care whether my build operates correctly or not. Your advice and direction is MORE than merely appreciated. As far as Shooterrex’s suggestion that I soak the BCG in MobileOne overnight…. Best I could do was oil the Hell out of it… I don’t have the MobileOne or a vat to soak it in… but I’ll still consider it if the other fixes don’t resolve my issues. I’d piss on a spark plug if I thought it’d do any good! 98Z5V, I placed the order for the Armalite EA-1095 spring last night and it’s in the mail. If the USPS maintains its current performance, I should have it somewhere between 4days and 1 month. (LOL, it’s hit-and-miss in rural southern Oregon). I drilled out the gas port using the #42 bit, but honestly, I think I shaved just as much metal off the bit as the port walls. The port IS slightly bigger, but I still can’t get the smooth end of bit shaft through the port. That barrel steel is no joke, and the only numbered bit set I could find locally was a cheap Harbor Freight set (but they are titanium bits). There’s one other place in the area I can try, otherwise Ill just have to order a set online. If it comes to that, I may ask for ideas on a quality numbered bit set manufacturer. I had better success shaving (sanding) the 100 thousandths off the buffer. I followed your instructions and measured BCG to bolt stop and got just a touch over 1/8in. The distance between the ears on the lower and the step-up on the BCG body is 1/4in. I’ll report back soon. Thanks again!
  5. Thanks for the quick reply 98Z5V, and all the recommendations! It looks like I’m ordering the Armalite EA-1095 spring, shaving/sanding down the buffer length by 100 thousandths, and drilling out the gas port with the #42 bit. I’ll let you know how these changes affect performance at the range. I should be able to check the BCG clearance at ears and bolt stop tomorrow and report back. Your explanation cleared it up for me and I think I can get you accurate info now, thanks. I didn’t see any indication of the BCG slamming into the lower under recoil, but better safe than sorry. I actually DID order the shorter gas tube originally (it’s lying around my workshop somewhere…) but luckily I saw a thread on this forum (I think) explaining the issue. Needless to say, I ordered and installed the longer tube before I ever tested the rifle.

  7. Oh, I forgot, I could fit the #43 bit in the gas port (#42 is too big).
  8. Thanks for guidance folks! I’ve posted my “Introduction” and taken the time to read thru the “Waterboarding” post (and a few others). Special thanks to 98Z5V, I understand the gruff, no bullpoopy, approach to providing assistance to us “newbies” here. After reading through just a few previous threads regarding “requests for assistance” I get a general idea of the source of frustration and exasperation. I’ve got 28 years diagnosing and resolving complicated fiber optic and telecommunications problems (both in-person & remotely) and nothing, NOTHING, is worse than trying to help someone who refuses to follow direction, can’t/won’t answer direct questions, or is simply bound and determined to “do it their own way” (and they generally blame you when it doesn’t work). So, please understand that I value your time and effort as well as my own. With that said, I’ll try to provide the “community” with the info y’all need to understand my issue with my AR308, and maybe you folks will be able to see what exactly I (or the parts suppliers) screwed up when I built this beast…. I managed to find a numbered drill bit set and digital calipers today, so I can provide almost everything in the “Waterboarding” list: 1.Do you have an Armalite AR10 recoil system? I may not understand the term correctly, but no, I don’t. I have an Aero Precision M5 .308 Rifle Buffer kit. 2.Buffer weight: AP advertises it as 5.6oz, but my digital scale shows 5.0oz 3.Buffer length: 5 5/16in 4. Extension buffer tube internal depth: 9 11/16in 5.What spring, length, coils, brand, color? The spring came with the Aero Precision M5 .308 Buffer Kit. It’s length is 12in, it’s has 37 coils (possibly 38… not sure the correct way to count the coils), and it’s bronze in color. 6.Gas system length: Rifle 7. Gas tube length: 15.5in. It’s the WC “AR10 rifle length” gas tube. 8.Photo directly into the magwell… (presumably for tube position so I’ve removed the lower for pic) 9.Photo of bolt face… 10. BCG clearance at ears and bolt stop…. Sorry, I’m not exactly sure what is meant by clearance at ears and bolt stop. Could I get some clarification? 11. Gas journal diameter: 0.8745. Gas port diameter: 0.0885 12. Photo and description of the malfunction or issue… Unfortunately, I didn’t snap a pic of the issue while at the range. I should be able to get back out there by this weekend, and I snap some pics. But the description is as follows: The rifle wouldn’t cycle 7.62x51 ammo nor .308 180gr ammo. I inserted a magazine, advanced top cartridge manually with the charging handle, fired, and when I looked at the BCG it was still closed and spent casing had not ejected. I could pull back the charging handle (with a lot of resistance), and it ejected the spend casing and advanced the next round. Not knowing what to look for, I didn’t observe the BCG while firing to see how much (if any) travel occurred, but I can check on the next trip. Also, when I tried the 165gr .308 ammo, it seemed to operate correctly, but I must admit that I don’t recall if it locked open on last round of the magazine. OK, that’s the best info I have at the moment. If you think we need the info, and someone could explain further about measuring the BCG clearance at ears and bolt stop, I will gladly provide it. I know, I know, I should’ve gathered more info (and some pics) about the malfunction while at the range, but it just didn’t occur to me at the time. Any direction on what, exactly, I can look for while at the range would be appreciated. Let me know what would help you folks diagnose this issue, and I’ll gladly do my best to provide. I’m fairly sure that this bad-boy should cycle more than one specific brand of ammo. Thanks again, in advance, for your time and insight.
  9. I don’t have a set, but I’ll drop by the hardware store tomorrow and pick one up. I’ll check the port size and report it back here, hopefully by tomorrow evening. Thanks again!
  10. Heya everyone! Greetings from Ore-GUN! Glad to find a gathering of relatively like-minded (or like-interested, at least) folks. I’m a fiber optic telecommunications technician (28years) who’s developed an interest in the AR308 and AR15 platforms and joined your forum help me along-the-way to building, shooting, and possibly hunting with an AR308. I’m pretty much new to everything about the platform (and online forums) and I’m slowly working my way thru some of the past threads on the forum. I’d like to reasonably educate myself on the bigger AR’s and hope you’ll excuse me for, what I’m sure will be, some stupid questions. From what I’ve read so far, there are some very knowledgeable folks on here, and many are willing to share their knowledge and experience with those of us struggling thru the learning curve. I hope to become a better AR10 builder and enjoy my rifle at the range and possibly, while hunting. Perhaps…. further down the road, I may try my hand at reloading.
  11. Thanks for replying Shooterrex & 98Z5V! Not only am I newbie to the forum… I’m a newbie to forums in general. Sorry. So please, feel free to let me know if not doing something right. Shooterrex, I went back to the Wilson Combat site and couldn’t find the specs on the gas port size, and it looks like I’ll need to get some digital calipers to before I can tear it down and measure it myself. I’ll get back to you when I can provide good info. 98Z5V, I appreciate your straight shot on how things work here. I’ll hit up the Intro section and read thru “Waterboarding”tonight. Sounds like someone “pissed in the pool” and ruined the game for all the players, it’ll be interesting to see how it played out in the “Waterboarding” thread. After I’ve gone thru the reading, perhaps I’ll get a better idea about exactly what info the forum will need to better diagnose my issues. And as with with Shooterrex’s request, I may need some tools to get that info. Thanks again, I respond back as soon as I’m able.
  12. Hi all! First off, let me start by admitting that I’m an absolute “newbie” to the AR10 platform. I own a S&W AR15 (M&P15 SportII) and have enjoyed tinkering with some small modifications. After seeing some new legislation passing in my state (Oregon), I decided that it might be a good idea to start building myself an AR10 308 while it’s still possible. So when it became evident that Ballot measure 114 was passing, I immediately purchased an Aero Precision lower at a local gun store and began this, sometimes frustrating, yet entirely satisfying project. When complete, I went to the local range with some friends (who had the same idea). I tested the 308 with several types of ammunition. The first, 762x51 149gr, wouldn’t cycle. The rounds feed and shot, but wouldn’t eject. I had the same results with 308 180gr, but the Hornady 308 165gr seemed to work fine. I also noticed that the 7.62x51 brass was distorted (see attached pic). I don’t know if this is common, or something seen during the break-in period, but I wanted to see if anyone in the community had any advice for me (I apologize if this has been addressed in previous posts on the forum, I haven’t had the time to read thru much.) Here’s the build: Aero Precision M5 lower & upper, AP M5 MOE LPK w/FCG, AP .308 Rifle Buffer Kit (5.6oz buffer), Wilson Combat 18” Super Sniper fluted stainless barrel (1/10), WC AR308 Nickel Boron BCG, WC 16.25” Handguard, WC AR10 rifle length gas tube (15.5”), WC lo-profile non-adjustable gas block (.875), A2 Birdcage flash hider, Magpul MOE rifle stock. After seeing others having issues with short gas tubes in the past, I checked mine and the gas tube extends a bit more than halfway thru the cam cutout in the upper receiver. Thanks in advance for any insights you may have.
