The ability to take down the weapon with a single pin is amazing, but due to production tolerance stacking some Scorpion Evo&#8217;s do exhibit more wobble or play between the receivers than others. Our pin is designed to tighten up that connection point and give the upper-lower receivers the rock solid fitment they are capable of. 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&#8230;) 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.<\/p>\n<p>Our HBI Spec Receiver Pin is compatible with all CZ Scorpion EVO 3 Models including: A1, S1, S2 Micro, Carbine, and Bullpup. Additionally, our Spec Pin is also compatible with ALL known handguard configurations, including those offered by aftermarket suppliers. If you have a CZ Scorpion 3 Plus model please consider our receiver pin dedicated to that platform: <a href=\"https:\/\/hbindustries-test.cospark.io\/store\/shop\/cz-scorpion-3-plus-receiver-pin-hbi-spec\/\">CZ Scorpion 3 Plus Receiver Pin<\/a>.<\/p>\n<p>NOTE: Installation of our Spec Pin requires disassembly and drilling of your bolt stop (item #44 on factory parts diagram).
