    I painted the 22 cal end cap FLORESCENT ORANGE. Hope I don't need to buy a replacement, but nice to know end caps are available.

    Perfect fit on Optimus

    Published by Lee Schwartz on 14th Nov 2018

    Well I write this review under the terms I’m a dumbass. I forgot to change the end cap on my Optimus and tried to shove a 30 cal through a .22 end cap. Anyone that’s smarter then your basic Marine knows it won’t fit! After contacting Griffin thinking I might have just ruined a huge investment they assured me as long as the baffles were intact and the suppressor as a whole wasn’t dammaged this end cap would fit perfect as a replacement. Received item in 3 days with some extra sticker swag! Over all review, don’t be a dumb ass and change your end caps!
