SYSTEMA PTW M4A1 Upgrade KIT
I'm a newbie here and I want to get some advice from you more experienced guys...
I have a SYSTEMA PTW M4A1 2008 version, the Smart Electrical Control Unit is damaged as far as I can see and I want you to tell me if you know something about it two things:
- Where I can get in general this replacement (Online) part and the rest of replacement parts for this model in order make an overhauling of it.
- Can I make an upgrade of this model based on the assumption of that framework it's compatible with the the new ones models as PTS Max, and MAD MAX? Which parts I must replace for achieve that?
Thanks in advance for your support guys.
