DNP Posted July 16, 2018 Report Share Posted July 16, 2018 I've been married for 15 years come this September, and was born in raised in California. What makes you think I've got a man card?

Albroswift Posted July 18, 2018 Author Report Share Posted July 18, 2018 Ok, back to ME... heavy buffer installed, first just dropped buffer and bcg into extension without spring and took a couple photos of clearance. Appears bcg clears ears at full recoil by .100 and clears stop by .200 (eyeball gauge, not caliper or feelers) Am I getting close enough for some more range time? Please?

Please? You're at the spec you need to be at, man. Remember, that poly bumper at the end of the buffer will compress, but that shiit is harder than skateboard wheels, so it won't compress much. You're good, as far as contact (by the BCG) with the lower. Recoil system solved. You used the Armalite EA1095 spring, right? Let's shoot it, and see what else crops up. Any other issues that come up will not be related to the recoil system. Quote Link to comment Share on other sites More sharing options...
Albroswift Posted July 18, 2018 Author Report Share Posted July 18, 2018 Yes, EA1095 spring, VLTOR Tube. Thanks again for all the help. I should be able to get out this weekend.

Albroswift Posted July 22, 2018 Author Report Share Posted July 22, 2018 Dang, range closed for biathlon. Changed out the bolt catch, the dremmel grind I did looked like dung. RM promised me the range would be open next weekend. Quote Link to comment Share on other sites More sharing options...
Albroswift Posted July 29, 2018 Author Report Share Posted July 29, 2018 Ok, got some range time this morning 150 gr rounds, both handloads and factory, operated flawless 100%. Very nice group. Brass landed at around 11:00, before it was landing in the 10:00 position. The 180 handloads got worse, every 3-4 rounds or so similar jam as before and the group was poor. Had 10 Winchester 180's left, same results. It was in the low 80's this morning, been hot all week. So: With the original light recoil assembly light and heavy bullets jamb 1/10. With the new heavy recoil assembly light bullets work great heavy bullets jamb 1/4 I have no problem just shooting 150's, but like to know why the hunting rounds dont work.

Albroswift Posted July 30, 2018 Author Report Share Posted July 30, 2018 One other thing of note (maybe) The jambs were not so crammed together tight as before, and the live round being chambered showed no where near as much bend/damage as before like the bolt was (maybe?) moving a little slower.

You have rifle gas system, or "midlength" gas system on that gun?... Came from Anderson with whatever length their assembly dude put in, but they only sell carbines I think. Questions: How much longer should it be? Do I need to gauge the gas tube depth in the key? How far into the key should it go? I didn't take my chrony with me today, didn't have a lot of time and was primarily checking function, but the larger then normal group and the hot weather make me think my hunting loads could have been very slightly over pressured. I don't see any indication of that, no flattened primers or flow but that load was developed in 40-50 deg weather. Wouldn't explain the winchester ammo but maybe hot chamber, and I didn't have much of that to test. Quote Link to comment Share on other sites More sharing options...
Albroswift Posted August 5, 2018 Author Report Share Posted August 5, 2018 Took a few measurements Put a wd40 tube in the gas tube and closed the bolt. .347 protruding Tried a couple times, similar measurements Quote Link to comment Share on other sites More sharing options...
98Z5V Posted August 5, 2018 Report Share Posted August 5, 2018 So, you don't have a Rifle Length Gas System, then. It's Midlength Gas System. I would bet my money that you're gonna end up just like this thread, right here: You need the Armalite AR-10 Carbine Gas Tube to fix the gas tube issue (backordered everywhere, right now - get on an email notification list with someone). I'd bet your gas port is too small, so that gas block needs to come off and the gas port in the barrel needs to be measured. You'll probably have to drill it up.

mrmackc Posted August 5, 2018 Report Share Posted August 5, 2018 Okay so what did you prove? that you have ,347 inches before the gas key impacts against the gas tube when the bolt closes? the only instructions I have been able to find say that the gastube end should protrude even with the middle of the cam pin relief cut, Quote Link to comment Share on other sites More sharing options...
Albroswift Posted August 5, 2018 Author Report Share Posted August 5, 2018 Measured the tube, 12.75 from the front of the gas block. Meased the key, tube to common point, .365 engagement into the key. Measued the key depth, 0.925 but there seems to be a step or ridge at 0.817, probably where the final reaming stopped. So safely I would think the tube could engage the key 0.800, which equates to 0.435 longer by math, or 0.347 by wd40 tube measurement Quote Link to comment Share on other sites More sharing options...
98Z5V Posted August 5, 2018 Report Share Posted August 5, 2018 We'll get this thing running, man - don't worry. Check that thread I linked, and what I had to do to get that one running right. I'll bet you're in the exact same boat here. Quote Link to comment Share on other sites More sharing options...
Albroswift Posted August 5, 2018 Author Report Share Posted August 5, 2018 Measuring from the end of tube to the approximate center of the cut 0.180. Any reason not to get a rifle tube and cut it? Quote Link to comment Share on other sites More sharing options...

Any reason not to get a rifle tube and cut it? Yeah, a huge reason. You don't have a Rifle Length Gas System. You have a Midlength Gas System. You need the Armalite AR-10 Carbine Gas Tube. Not an imitation, the real one. AR15 Midlength gas tube: Overall Length: 11-3/4" Armalite AR-10 Carbine Gas tube: Overall Length 12 1/16" That right there fixes your short gas tube. I think you have a gas port problem in your barrel. You need to remove your gas block, and measure the gas port size. All the specs for what you need are in the thread I linked above. We will get you running, and running right. Start with the steps I've listed above. I'm crossing Anderson off my list for .308ARs. They can't figure it out, either...

Albroswift Posted August 5, 2018 Author Report Share Posted August 5, 2018 I went through the thread, that receiver took a beating! Glad I caught mine after a couple of slams, don't feel so bad now. Dont see any of that damage around the relief cut, and my ears look pristine by comparison. Anderson's ar308 so far: Ar15 recoil tube and spring Ar 15 bolt catch Ar15 gas tube Get the feeling that they never test run their builds. Loaded some 180 gr rounds with a different pressure curve, similar to the curve that the 150 gr bullets have that ran flawlessly last weekend. Besides the tube length problem, think I was way over the top on gas pressure with the hunting rounds. Also just got a 6.8gr buffer. So while waiting for the correct tube have a few things to try next session. Shot pistols and revolvers this weekend, picked up a SW E series 1911 few weeks ago that shoots like a dream right out of the box, point of aim, crisp trigger, shoots match and seconds flawlessly. Awsome prints off hand at 50 yards, rivals my Hamilton Bowen built 44 revolver Finally someone gets it... Quote Link to comment Share on other sites More sharing options...
