So I recently purchased a AA T11 brand new sealed out the box ofc, out the box it shoots 200fps which is pathetic NOW i do get they cant really sell high powered guns because of regulations and all that I completely understand that, and all the internals are plastic(spring guide, piston)
now today i received an M145 spring to put into the rifle so that i can actually hit targets without spraying and praying, now here is the big issue that i find with this gun, It is impossible to upgrade the gun out the box im not sure if its a tolerance issue with the diameter of the cylinder or the spring guide but the stock trigger will not cock the gun it pulls back but immediately slams the bolt back into the cylinder, so i take this as the gun is not upgrade compatible out the box without changing the stock 0degree trigger and the cylinder with the spring guide, so basically DO NOT BUY THE ASIA VERSION OF THE T11, if you can get the American version its alot more expensive but i would assume that out the box its not such a pain to work on and it should at least shoot straight, i am extremely disappointed in the t11 seeing as i have to go blow even more cash on the gun changing every single internal part, the whole reason i bought the t11 is because it came stock with a 0 sear so that i didnt have to go an buy an expensive aftermarket sear but now i do anyway, just a heads up for you out there looking at buying the asia spec T11, Any help is more then welcome for all you airsoft pro technicians out there!!
