i'm new to the forum as for posting but have been reading for a couple of months.
my question is about the cup seal and valve pin in my MR1. i had them out today and found the cup seal was stripped out and the valve pin was loose. i had an extra cup seal so i changed it. but i don't know how long it was stripped out, would it cause any malfunction ? i have had a lot of problems choppin' balls since i put my rocking trigger on but i'm getting a good force-fed hopper soon.

It could have caused poor sealing of the cup, improper opening of the valve, improper airflow past the pin, even air volume and direction problems due to mis-alignment of the valve pin.
All these things are probably not the cause of your chopping though. Your new frame is way too fast for anything less than a fast, force fed hopper like a Fasta, HALO B, VLosity or something like them.
Get the hopper and test fire the marker before you worry too much about it...chances are that the hopper will cure your chopping.
