Zero/Patterning question
Hi all,
I have a Mossberg 590A1 with GRS that I'm thinking of getting a mag extension for. When I put the extension on, will my shotty have the same zero and patterns as it does with the stock magazine cap, or do I need to re-zero and re-pattern it? TIA for any info anyone can give me.

Yes it would be the same with the possible exception of harmonics affecting things a tiny bit... But we are talking about a phenomenon reserved for longer range rifle shooting so I doubt any normal fella could tell.

It shouldnt affect the point of impact enough to notice.
