I had another problem with my highly upgrade m14 CarzyHorse last weekend, So I go on the the G&G
websitehttp://b2b.guay2.com/ to do some QA reading and I found this
We recently notice that some of our M14 rifles have pressurization(airtight) problems , which is cause by the tiny space between the nozzle and the Hop-up rubber , it will result to some decreasing of the muzzle velocity. In order to solve the problem completely , we redesign the tappet plate and reset the tappet spring . Now our new rifles all equip with this new tappet plate and the tappet spring . To whom already bought our M14s(including the S.O.C. 16) , we are gladly to provide the service to exchange the old tappet plate and tappet spring without any charge . Please contact your local distributors for
the service .
I email them and not more then 15mins went by till I got a reply
The email stated they would send me out all need parts, Will keep you guys posted on outcome
