But... They are nice and shiny! 😁 In all honesty mate I don't think they do sod all apart from lighten our wallets, and give us an excuse to stripdown a gun and replace perfectly good parts.

I had a TM PX4 that I fitted a inner barrel and and a new piston head to. Comparing it with my completely stock TM HK45T it did not shoot any better whatsoever. 

I've decided to not touch my 45 and just leave it as it is. It works perfectly, and I really doubt I can get much more performance from it. 

The only thing I have done is fitted the purple gas routers for the mags, but I took those from the PX4 mags. Not sure if they do anything either, probably another case of 'upgrading' for the sake of it... 

I've put in purple gas routers too for my hk45. In addition, some laylax neo-r bullet valves, because you still get the same amount of shots (3 mags) but at slightly higher velocities (+12 fps); it doesn't have 4 ports like a normal valves, just a big one like a semi circle and directs all the gas upwards instead of all over the place. The neo-r valve is also adjustable in power which is cool af.

Those 2 and a maple leaf autobot have made it an even better beast.
