No hardware included - Battle Arms 9mm Development Enhanced Bolt Catch

This bolt catch does not come with the roll pin, plunger, or spring necessary for proper installation. Which is a shame, because the primary draw of this product compared to similar "enhanced" bolt catches is the price. Once you factor in the cost of sourcing the hardware yourself, there's little reason to get this over one of the other options on the market. BAD could certainly get these parts for only a few cents a piece at distributor prices, unlike the 6-10 dollars end users would pay.
