    For the price, the gun is great value. Very smooth, powerful and accurate. Shoutout to the guys at Renegade Blasters – 2 days shipping and received some real handy freebies as I bought a fair few guns.

    If you need a go to gel blaster store to keep coming back to, I reckon Renegade Blasters is by far the best.
