SRS SSG VSR Steel FPS Adjuster Rings (9mm)

Passt sehr gut und eine super Verarbeitung.

Exactly what i was needed

Perfectly machined and very easy to install or swap out. Come in good size variances. I have a 2+ Rapax spring and the 6mm and 4mm ring installed. I sit comfortably at 322fps at 2.2j.

Must have for tuning on field! Seems to add up to 0.5 ish J if all are used at once on a srs a2 covert. Very convenient to have at hand!

Doen wat ze moeten doen goede kwaliteit!!! Prima product

Helped my fine time the FPS off my Silverback SRS to just where I wanted it to be.

Great product!
