[ILLusion]

- The right safety lever can be tightened up by pinching the tab inteface on its pivot.

- The "back strap" as you call it, is called the main spring housing. It contains the main spring, not the recoil spring. The recoil spring is located underneath the outer barrel, and is responsible for controlling the slide's... RECOIL. LOL. The main spring is also called a "hammer spring" in airsoft lingo.

- I agree that the recoil rod setup in this gun is stupid and makes no sense. If they're using a full length recoil rod like this, they should cut off the post on the hop up chamber. Otherwise, change it to a proper spring plug and spring guide setup (as a Kimber Warrior should have). It would make disassembly a million times easier.

- There's a high possibility you will not have the option to replace these sights ever, as they use a proprietary dovetail mount from what I recall. Not without re-machining, anyways.

- Socom Gear magazines will NOT fit Marui compatible guns. The two are proprietary from each other.

I've reworked a couple of these now. The biggest issue I had in them was the slide to frame slop/wobble. Thankfully, the craptastic receiver insert is made with such a soft and malleable post metal, that I was able to peen the rails down to create a tighter interface with the slides. It reduced wobble DRAMATICALLY after a bit of working in, and the final result was just as tight as some of my high end race guns.
