Sons of Liberty Gun Works MK1 Maritime Bolt Catch Features The Sons of Liberty Gun Works MK1 Maritime Bolt Catch extends the working surface of a standard AR bolt catch giving shooters a larger target to engage when locking the bolt back or releasing it during a reload. A serrated surface adds texture that improves purchase under recoil with gloves on or in wet conditions where a smooth factory catch can become difficult to manipulate. The extended control is designed to speed up manual bolt release during competition stages or duty use where every fraction of a second matters. Because the part is precision machined it maintains reliable engagement with the bolt carrier group once installed. The kit includes the XP spring and plunger needed to complete the installation so shooters are not left sourcing additional small parts separately. A matte black finish keeps the catch visually consistent with the vast majority of mil-spec AR lowers already on the market. Sons of Liberty Gun Works designs its small parts to fit most mil-spec firearms making this bolt catch broadly compatible across standard AR-15 builds. For shooters looking to speed up and improve the feel of their bolt manipulation the MK1 Maritime Bolt Catch is a focused well-made upgrade.
