Description
The HBI Receiver Pin for the CZ Scorpion 3 Plus will minimize the pesky play or motion between the upper and lower receivers. The ability to take down the weapon with a single pin is amazing, but due to production tolerance stacking some Scorpion 3 Plus builds do exhibit more wobble or play between the receivers than others. Our pin is designed to tighten up that connection point. The head on our pin features an undercut groove not found on the factory pin; this groove accepts many improvised pry tools (driver, blade, etc…) to aid in removal for field strip and weapon take down. The HBI Spec Pin is machined from 4140 Chromoly and finished with black nitride.
This Receiver Pin is only compatible with CZ Scorpion 3 Plus models. If you have any other CZ Scorpion (such as Evo 3 S1 or S2 pistol or carbine) please consider our receiver pin dedicated to that platform: CZ Scorpion Evo 3 Receiver Pin.
NOTE: It has come to our attention that *SOME* of the Scorpion 3 Plus 7.8″ pistol models require drilling of the lower receiver (similar to our Evo 3 pin procedure) in order for our receiver pin to fit. At this time we believe our receiver pin is still a drop in installation with all Scorpion 3 Plus Micro models on the market.

Took some of the loose fit out but not enough to justify replacing the stock pin. The HB pin size is still to small…OEM pin is .194, HB pin is .202, the hole in the “block” ( not sure what it’s called ) is closer to .212

Installation was smooth and went as expected. It tightened up the upper and lower receiver quite a bit. Well worth the cost of the pin.

This pin corrected about 50% of the play between the lower and upper of my CZ Scorpion 3 Plus Micro. The HB pin didn’t fit right out of the packaging. The fit was simply too tight. Instead of drilling into my gun, I sanded and polished the HB pin to a nice and snug fit. Now about half of the original slop has been removed and the fit between the upper and lower is more snug.
