After a trip to 2 of the local gunsmiths both of which said it was not my gas tube . One even had his own AR10 there in the shop for comparison. And gas tube was same position as mine . Anyways both seem to think was the buffer tube spring. So I purchased the spring which is longer then The one that came with my A2 stock. Long story short just got home from the range . AR10 is now perfect shoots great. With no more problems . Again thank you for all your input and advice

First want to say to all of you THANK YOU for all the help . I guess I will check with my local gunsmith and see if this problem can be fixed . Also I will get in touch with DatonaTactical and see if they will fix problem. Will post update in a few weeks hopefully this beast will be shooting properly. Again Thank You

specs = spring 12.25 L coil count 35 . Buffer 5.25 L not sure of weight. How many rounds thru 80. Using magpul magazines if cycled manually yes bolt locks back. Lite lube Purchased complete package from Daytona Tactical (minus the lower). Originally came with collapsible stock . Replaced with A2 full stock buffer and spring included. Never fired with collapsible stock.

DPMS upper also the spring and buffer for A2 buttstock are Leapers UTG mod# RB-T308B is supposedly 308 version. Any recommendations on which buffer spring to use

I built an AR10 using polymer80 lower . All went well all parts fit perfect only one problem. Will not cycle and not sure where the problem is. Fires good but will not feed second round also when I load just one round in magazine bolt will not lock open. Am suspecting buffer or buffer spring ? I have a Leapers UTG A2 full buttstock. Please anyone have any ideas ?
