Depends how much you use it.
I used mine a lot. Sometimes as a primary. Inside and out.
Every weekend for two years, thousands upon thousands of rounds.
So all told, I'm not too bothered it finally died.
The thing that finally died was one of the loading arms snapped.
I swapped to an ASG for a day - and it died. Same thing happened.
So bit the bullet and bought another TM.
If I get two years out of the new one, I'll be a happy boy.
Dooooooooo iiiiiiiiiiiiiiiiiit!
They're cheaper than ever at Fire Support. £129. https://www.fire-support.co.uk/product/marui-mk23-socom-gas-nbb-pistol
I'd rather leave my kids a nice new mk23 than an extra £129 in the bank if I kark it 😂
