KAK Industry AR-15 LPK Pin and Detent Kit Features The KAK Industry AR-15 LPK Pin and Detent Kit rounds out a lower parts build with the small but essential hardware often overlooked until a build comes up short. Included are the pivot pin and takedown pin which allow the upper and lower receivers to be joined and separated along with their corresponding pivot and takedown detents that keep those pins seated under spring tension. The hammer and trigger pin secure the fire control components in place while the bolt stop plunger and bolt stop roll pin keep the bolt catch functioning correctly during the firing cycle. A selector detent is also included ensuring the safety selector clicks positively between settings. Finished in black to match standard AR-15 hardware this kit saves builders from having to track down individual small parts separately when completing or repairing a lower parts kit. KAK Industry was founded in 2011 specifically to address a shortage of quality American-made AR components at prices that make sense for builders and hobbyists alike. Having these commonly needed detents and pins on hand helps avoid a stalled build due to a single missing or lost part. For AR-15 builders looking to complete their lower parts kit with dependable American-made hardware this pin and detent kit covers the basics reliably.
