Want to Trade my Used, but in Great Condition, Mk4 M-LOK Geissele SMR for your Mk8 M-LOK Geissele SMR, Used or New. Rail, dogbone nut, and crossbolts only. We both keep our own barrel nuts, since mine is already installed and they are the same.
PM me and we can exchange photos and what not.
I realize my Rail costs $25 more than the Mk8, but if yours is Brand Spanking New, I’ll trade ya straight up… otherwise you can throw a little cash or a couple pmags or something to even the deal.
Thanks!
