Thank you, friends.
The Nylon fires 300 cartridges with excellent reliability. I managed to hit a beer can at a paved 80 yards offhand and felt happy doing so.
To disassemble, I simple remove the top cover and charging handle, remove the barrel, slide out the bolt/spring and the cocking piece/spring. That gives total access to the rails and internal bearing surfaces. Reassembling is simple but you have to hold the trigger and press down the sear with something whilst sliding the cocking piece back home, easily accomplished.
I however never go past this as one it is unnecessary and two I have heard countless nightmare stories about getting the gun back together again.
