Great 5rd mags load easily handy for on the spot quick change outs and they also look pretty cool great item would definitely buy again
Perfect for legally hunting with your favorite MSR. Easily carry several different types of ammo, switch outaseasy as push a button, rack clear, insert new mag, sent bolt home.Great product great price, free shipping , to my door in less than a week

Not the greatest but for the price it'll do in a pinch they are a little finicky loading but I've never had a problem with it not pushing out bullets lol
