Before you do anything, install a Murray's Firing Pin.
After that, tacticool is dumb
Personally I'm a fan of a gorgeous wood stock on them, but anyway.
- They make a rear cover with a scope mount
- They make high-cap removable mags for them (or you can have it modified it to accept AK mags)
- They make every kind of stock imaginable. They even make bullpup setups for it.
All of this is shit though unless you remove the danger of the firing pin sticking and accidently making a full auto weapon. It's the only real weak point of the gun (well, outside of it being cheaply made and everything that goes with that)
