LRBHO Hardware Kit for Pistol Cal Upper Receiver – Glock Style, Bolt Hold Open, Adjustable

This kit is a spare part only, NOT intended for uppers without the LRBHO feature.

The LRBHO Hardware Kit is designed to enable Last Round Bolt Hold Open functionality on your Glock-style pistol caliber upper receiver. Once assembled, the small "hook" end of the wire form in the upper is activated by the follower of an empty Glock magazine, engaging the bolt catch on the last round fired, ensuring the bolt locks in place.

If the bolt does not engage or engages too early, slight adjustments can be made by carefully bending the "hook" end. This adjustment allows you to fine-tune the functionality of your setup to ensure proper bolt lock timing, whether it locks faster or slower depending on your needs. Slight adjustments may be required depending on magazine specs, magazine wear, and bolt catch variations.

Features:

  • Function: Ensures bolt locks after the last round is fired using Glock-style magazines.
  • Adjustment: Small hook-end adjustment for fine-tuning the bolt catch engagement speed.
  • Compatibility: Replacement part only for LRBHO pistol cal upper receivers
  • No Warranty: No warranty is issued on replacement parts.

Perfect for ensuring proper function in your AR-9 or other pistol caliber carbine builds, the LRBHO Hardware Kit offers an easy solution to implement a bolt hold open system in your Glock-style setup.
