I have been thinking of TM KH45 as my friend has one. He was telling me that finding parts for it was a bit hard, specially mags.
When it comes to maintaining my guns I am willing to go the extra miles. I do not like to shop too often for new stuff or replacement parts. Even though blow backs are awesome, I wonder how long they last before breaking.
Going AEG primary and gas secondary makes sense.
Thank you for all your ideas
