ION W/ Blackheart board
Deadlywindz body frame.
Easy to put together. Rugged. Durable.
The most key weakeness would hae to be the slight weight it adds
I bought this frame before I bought my Ion. The Ion was my second gun. I had no issues putting it together. I do have SP QEV installed. The front screw can be placed in with no major issues and I have big fingers. All you have to do is drop it in the barrel and let it roll into the hole. I am not the most experienced person when it comes to maintance of a paintball gun but I can brake this gun and frame down in minutes. Clean up can be easy I toss mine in the sink and scrub it with a dish brush.....No scratches so far.....
If you like military sim guns this is good choice. I have received many complements
