Hey guys wanted to get your thoughts on how much a difference I will get in terms of better accuracy at 300ft. The barrels are both from RA tech, I haven't got the 650mm 6.03 barrel yet. I gun im using is my HPA kc02.

here the hpa kc02

and the chrono with madbull .40s

thanks

I have used both, and found that the 6.03mm gave me more consistent groups.

I would go with the 650mm 6.03 barrel, you use HPA so you should see a velocity increase with the longer barrel. By the way, nice rifle!

Thanks for comment

However, the bad thing about a barrel that's too long is that it tends to wobble, so put a ton of spacers on it!

Spacers won't work beyond the outer tip of the main outer barrel because alignment issues.

I would say go with a 6.03 510mm, unless you are using the extra length to try and out an LRB in it.

If I had the option to go for that one, then I probably would too.
