Johnny1982 Posted February 3, 2021 Report Posted February 3, 2021 Hello everyone I need help I have been building my Aero for about 18 months I finally was able to get the last few parts. Well to my horror I go to my local club to run it and it will not cycle at all whatsoever will not lock open on last round fired. The gas block is on correctly I know it because the carbon ring was perfect around the gas port. So I know it’s not that. So here is my build list Aero M5E1 builders kit bought from Aero,Krieger 20” rifle gas system .936 gas journal m110 profile barrel with JP bolt matched to the barrel at Krieger, superlative arms adjustable gas block, the buffer is a Brownells AR10 rifle buffer,the action spring/buffer spring is also from Brownells AR10 rifle spring, Magpul PRS Gen3 with the rifle receiver extension/buffer tube, and a Geissele 2 stage trigger flat shoe, what is the matter with this rifle it’s all quality parts all of should be working but it’s not. All I want is for my rifle to run I saved a lot of money and waited a long time to get it together. Any help from you guys that know this system would be greatly appreciated.
edgecrusher Posted February 3, 2021 Report Posted February 3, 2021 Post up details of your recoil system. I don’t care what brand it is. In another thread you stated you cut spring coils. That right there tells me something isn’t correct. Need physical measurements and weights, coil count and inner depth of buffer tube.
Johnny1982 Posted February 3, 2021 Author Report Posted February 3, 2021 buffer tube is 9.75” long Buffer length is 5.300 buffer weight 21oz total weights in side the buffer 2.5 oz per 6 total Action spring 35 coils 30 if you subtract the 5 I cut off actions spring length 10.75” total missing 5 coils
shooterrex Posted February 3, 2021 Report Posted February 3, 2021 That buffer should only weigh about 5.3oz total. That seems to be at least part of the problem.

The right spring and proper weight buffer is the first step on solving your problems. Edited February 3, 2021 by shooterrex

Johnny1982 Posted February 4, 2021 Author Report Posted February 4, 2021 Okay what do you suggest for a starting point. Also if I have a adjustable gas block where would be a good starting point for that

Johnny1982 Posted February 4, 2021 Author Report Posted February 4, 2021 Okay well I now have something to go on tomorrow it’s off to the club to run this pig I’ll definitely post updates. Thanks SOOOO much guys I’m extremely than 6 hours ago, shooterrex said: https://www.armalite.com/SACItem.aspx?Item=EA1090 https://www.armalite.com/SACItem.aspx?Item=AR10REKIT02 Call them they don't list the spring on the web separate. The right spring and proper weight buffer is the first step on solving your problems. That’s exactly what my buffer looks like that I have now. And same with the buffer tube as for the spring I ended up buying a new one and it looks the exact same.

shooterrex Posted February 4, 2021 Report Posted February 4, 2021 Looks like and being the same are 2 different things. Weights and spring material and spring rates matter.
