hi im new to this and i am only really doing this for fun with some friends in their garden and i wondered if anyone knew if you could upgrade/modify a spring powered gun as i didn't plan on spending more than £50
i decided to get an sm6 and it works well its accurate and strong enough but i wondered if you knew any cheap springs that would just add a little more
Honestly I wouldn't even think about upgrading them internally. They're decent enough for messing about in the back garden anyway. Make sure you have/get some eye protection.
