HFC VSR11

[KINGJASON0707]

Hi all, I have a VSR11 and have just fitted a few upgrades

AA tight bore, AA M150, AA spring guide, AA piston, 9 Ball bucking, ASPUK barrel spacers, ASPUK hop arm, ASPUK cylinder head

But the bolt pull is VERY stiff, seems very smooth (no snagging) just bloody stiff. Was expecting it with the M150 but not this bad. Any ideas for a lighter pull? Cheers

The stiffness is likely down to the 45deg. Piston and trigger set up.

My old tm vsr had this issue as I didn't upgrade to the 90deg. Set up.

My cyma m40a3 has the 90deg. As standard and it's so easy to slide the bolt back.

If the pull is stiff, then it's not the 45 degree. If it's pushing the bolt back stiff, that is because of it. Check the cylinder in- an outside for scratches. If there aren't any, and the cylinder moves freely without the spring guide stopper in, then it's just the spring stronger than you.
