11-87 O-rings for 20 ga

[blargon]

Does anyone know the size or part number for the 20ga 11-87 O ring?? I bought 50 viton orings for my 12 ga, but the 20ga is smaller. thanks for any info.

I ran across a reference on another site that suggested that the correct for a Rem 11-87 20 gauge o-ring is

#32 Plumber's o-ring

or a

#19 VITON o-ring from a hydraulic supply store.

ID-13/16
OD-15/16
WID-1/16

I have NO way of verifying this. It's just a reference I found.

Wrap a cloth sewing tape measure around your mag tube and see if it's approx 13/16". If so there's a good chance the reference is correct.

Buy 1 and see if it fits. If not you're out a quarter and accept my apology.

I only buy the VITON rings for my Rem as they are much more chemical and heat resistant than the plumber rubber rings.
