ironmonster Posted April 9, 2015 Author Report Share Posted April 9, 2015 Actually I got a lathe, I could just turn a new bumper for the buffer that was a bit longer out of UHMW or something Quote Link to comment Share on other sites More sharing options...
blue109 Posted April 9, 2015 Report Share Posted April 9, 2015 even worse! after you finish toms quarter stacking experiment, you can use them to cover half the cost of a standard tube from psa. should clear everything right up. :D Quote Link to comment Share on other sites More sharing options...
survivalshop Posted April 9, 2015 Report Share Posted April 9, 2015 (edited) :) no crap Blue ! once again....its always the "trick parts" that put you in the "trick bag" ??? Wash I can't grasp the price ether . What I don't understand is , how can the BCG come back too far with a Tubb's flat wire spring , that's one long spring , it is supposed to compress more , because of its design , but still , thats a lot of spring . Here it is next to a DPMS 308AR Carbine spring . Something is not to spec's in the Receiver Extension. Op said its 7" deep & that's correct , maybe the Tubb's FWS is for an AR 15 & not a 308AR ? I would like to see the Lower Receiver & extension photo's with out the Upper attached , inside & outside & a photo of the BCG with a measuring scale next to it . . 98 is right , this is the second one in just a few days .

AngelDeVille Posted April 9, 2015 Report Share Posted April 9, 2015 $115? Nope $150.... http://www.primaryarms.com/PWS_Enhanced_Buffer_Tube_Mil_Spec_p/4btmilb1.htm does it wash your balls for you too? Quote Link to comment Share on other sites More sharing options...
washguy Posted April 9, 2015 Report Share Posted April 9, 2015 does it wash your balls for you too? nope doesnt do that....but it prevents carrier tilt as advertised....NOT <lmao> wash Quote Link to comment Share on other sites More sharing options...
blue109 Posted April 9, 2015 Report Share Posted April 9, 2015 well...to be fair...that carrier didn't tilt! Quote Link to comment Share on other sites More sharing options...
mrmackc Posted April 9, 2015 Report Share Posted April 9, 2015 Sounds simple even to me. (1) remove upper from lower. (2) find and depress buffer detent button pin thingiee .....it is spring loaded! (3) dodge stuff flying thru the air! find flying stuff. (4) drop several quarter dollar coins down into where the stuff flew out of, how many quarters to be determined later,right? (5) stuff flying stuff on top of the coins, spring first,then the buffer thing little end first. (6) you gotta hold down the buffer detent button thingie and get the buffer thingie behind the buffer detent button holding against that spring pressure and let the pressure off the buffer detent pin while holding the buffer behind the buffer detent pin thingiee. Okay is that how I do that? Later I can see if the mod worked? Something about if the bcg will go back far enough so that the bolt holder open thingiee holds the bolt open? You all hang with me and maybe I'll get this thang figured out, thanks Quote Link to comment Share on other sites More sharing options...

ironmonster Posted April 10, 2015 Author Report Share Posted April 10, 2015 (edited) You can clearly see the difference in the 5.56 Tubbs spring and the .308 Tubbs spring Spacer I machined How far the carrier goes in with the spacer in place If you look really close you can see the buffer retainer pin does not come in contact with the buffer when the upper is mostly closed Edited April 10, 2015 by ironmonster Quote Link to comment Share on other sites More sharing options...
ironmonster Posted April 10, 2015 Author Report Share Posted April 10, 2015 GEEZZZZ I had a double post so I deleted the wording, the double post still showed the pics so I edited just the double post and deleted all the pics Now the pics vanished from both posts. I'll just post the pics, If you cant figure out what they are ask Quote Link to comment Share on other sites More sharing options...

Toolndie7 Posted April 10, 2015 Report Share Posted April 10, 2015 (edited) Ironmonster, any chance you can get that tube in one more turn? That's a 16 threads per inch thread size if I remember right, if that's the case you would be crashing by 1/16" maybe you could measure your dent in the receiver and see if it's about that depth? I'm just trying to think simple. Edited April 10, 2015 by Toolndie7 Quote Link to comment Share on other sites More sharing options...
ironmonster Posted April 10, 2015 Author Report Share Posted April 10, 2015 I can't see how that would matter as it is already hitting the buffer tube in the fire control area, the operating length won't change even if the tube is turned in one revolution Quote Link to comment Share on other sites More sharing options...
survivalshop Posted April 10, 2015 Report Share Posted April 10, 2015 Ironmoster , with the BCG in the the lower , like it would be in full recoil & with the Bolt set against the Bolt Stop , as it would be with an empty Mag. in , looking it back , does the BCG hit the Rear of the Lower Receiver ? This is done of course with out the Upper Receiver & Buffer? Spring . Photo? Quote Link to comment Share on other sites More sharing options...
ironmonster Posted April 10, 2015 Author Report Share Posted April 10, 2015 If it will cycle with the spacer in there I'm ok with that fix. It's obvious the buffer is too light and/or its over gassed but the buffer bumper still should stop the carrier before it crashes. The PWS tube is 1/8" longer than another random buffer tube I grabbed (7" vs 6-7/8"). So that plastic spacer should do restrict it. However it still means that buffer is slamming into the back of the tube every round fired. I think it's normal to touch but considering the damage done the carrier is still going full tilt at the back of the cycle. With the spacer the bolt locks on the catch and will move about a 1/4" back from there before everything bottoms. I ordered the Tubbs cws but I think as far as lenght goes it hurts not helps, it adds lenght to the carrier, I need the carrier to be shorter. Maybe the weight would be enough to slow it before it bottoms but it seems to me that an adjustable gas block is a better solution. Quote Link to comment Share on other sites More sharing options...
ironmonster Posted April 10, 2015 Author Report Share Posted April 10, 2015 I take that back, the Tubbs adds lenght in the middle which will do some good. Brain fart this morning Quote Link to comment Share on other sites More sharing options...
washguy Posted April 10, 2015 Report Share Posted April 10, 2015 (edited) Iron so lets start from the obvious here are pics of my carrier and then the opening diameter from inside the buffer tube at the mouth and then the carrier shoulder which prolly is causing the damage you there on the measurements with yours? the easiest way is to put a plain ol buffer tube on with a car308 buffer and a car308 spring ....if that doesnt work....you got bigger probs :) Wash Edited April 10, 2015 by washguy Quote Link to comment Share on other sites More sharing options...
ironmonster Posted April 10, 2015 Author Report Share Posted April 10, 2015 Well, the O.D. Of the carrier does not matter as long as the I.D. Of the buffer tube is sufficent that there is clearance, it does. The cross section of the sectional change in the carrier does not matter because no matter what size it is it's still not going in the buffer tube. The only measurements that I could see are relevant is from the rear of the carrier to the sectional change in the carrier, the depth of the buffer tube, the compressed thickness of the buffer spring and lenght of the buffer itself Quote Link to comment Share on other sites More sharing options...

ironmonster Posted April 10, 2015 Author Report Share Posted April 10, 2015 Other than changing out the Tubbs spring changing the rest of it would have no effect, the only way the spring could have any effect is if it's collapsed hight was thicker thus limiting the carrier movement but that would just mean everything was collapsing to a dead stop, still a crash and not the intent of the system(is it?) I can't imagine the goal is to collapse the spring 100% so the carrier crashes to a dead stop at the end of the stroke. I need a heavier buffer, a stronger spring or less gas, the spacer I put in the buffer tube makes it impossible for the carrier to contact the buffer tube boss. The other thing is this buffer tube is not coming out, ever. After the damage done to the end it's going to damage the receiver and probably destroy the tube as well. Since it will work as it is and they both may be junk if I try and tear them apart it seems smart to just deal with it as is. Quote Link to comment Share on other sites More sharing options...
ironmonster Posted April 10, 2015 Author Report Share Posted April 10, 2015 I just ordered 6.5oz buffers and his recommend springs from heavybuffer.com $296 shipped for two springs and two buffers. Hope it helps Anyone want to buy a couple of very slightly used high zoot Tubbs flat coil springs? Need a couple of standard DPMS buffers?
