You will not find these at a better price guaranteed. These 4pc flash hiders have 24x1.5RH threads, They fit the AR-M1 . AR-M9F . SAM7SF . AR-M4 SF . SAM7K . SAM7R . SLR-101 . SAM5 and others. I’ve been waiting to get them into the USA because they are so hard to get past customs. But I have a few that I’m selling for much less than kvar US made crap. I take discreet Friends and family PayPal or postal money order can also accept bank check. These are ((($250 shipped)))) ((((Insurance can be added for an extra cost of $3.50 and isn’t required but not responsible once it’s been shipped and photographed)))))))
