I was hoping I could pick the brains of a few more knowledgeable folk. Earlier this year I picked up an SPR new, unfortunately it’s only managing 240-250fps. That’s on stock internals, hop up at position 3 and using an 11.1 lipo. I’ve played several games since I purchased it and it’s never caused much of a problem but it supposed to be at 350 and my sites limit is 370 so I’d like to make use of it. So I was hoping to get an idea as to what the cause could be and perhaps even recommendations for replacement parts.
If it makes any difference I am Uk based.

What weight BBs did you test?
Also, what kind of chronograph did you use?
