A custom built KWA mp7 with custom special steel reinforcements installed. Modified: - angel custom stronger spring - stainless steel reinforcements - 3D printed HPA drum magazine adapter (well made to prevent leaks, uses steel-to-steel design so no crappy air leaks) Gun shoots perfectly with no issues, stock slides out nicely, ask if you need more details. The only issue is that the front cover latch broke, but has no issues while the compensator is on. Buyer pays shipping, please talk to me prior to purchase for better shipping rates.
