Hello, i'm selling my unique M4 because i'm leaving the country soon.
As you can see in the pictures of the invoices, many upgrades have been made, even expensive ones I would say.
Now i have 2.3 Joule with 0,32bb. And more Joule if you will use 0,40. But for me 0,40 are expensive for every sunday.
At 50mt is very hardcore. Until 75mt you will have no problem but you have to do your test to find your perfect bb solution because probably with 0,40 you will have more precision.

Is included:
4 S.A. Mid.Cap magazine
1 Battery Charger + S.A. 1300 LIPO Battery
1 Tracer Suppressor
1 S.A. rifle bag.
