Pricing up the GHK AK-74:
 

Internals:
Heph firing pin, auto lever + sear = £40 (inclusive of shipping)
GBL ironman hop unit = £50 (samoon)
GHK Chrome bolt = £60 (inclusive of shipping)
W&S FT recoil kit = £42 (from WGC)

Even though the internals and bolt are brand-new, I will reduce them by 25%
Internal totals = £144
 

The rifle itself is a little worn and beaten in places, especially the OB which has some scratches.
But considering it was in storage for 5 years from the previous buyer, it's in decent condition.
 

As the new UK prices for GHK rifles are fuckin insane, I will price it based off an older rifle.

£520 / 100 * 70 = 364

So the total price would be £508 excl. shipping. It will come with a standard 5.45 GG magazine too.
