Building out your own LS5? You’re in the right place.

Our LS5 Trigger Housings are designed for customers who want to select and install their own grip, safety, and trigger. Please note: these housings do not include a grip, safety, or trigger.

If you’re looking for a ready-to-go option with the grip, safety, and trigger already installed, check out our Complete Trigger Groups.

The LS5 MP5 Trigger Housing is precision-machined from billet aluminum and designed to provide a more ergonomic shooting position for semi-auto MP5 platforms. The firing hand is moved approximately 0.6" forward and 0.4" upward, positioning it closer to the bore axis for improved ergonomics and control.

The LS5 also allows the use of compatible AR-style triggers, giving you more options when configuring your trigger group. The included bespoke ejector lever is CNC-machined from 4140 alloy steel, then heat-treated and nitride-coated for durability and long-term performance.

    Please Note!

    Full-Size Semi-Shelf: This variant is only available in our updated HK416-style pictogram. Please refer to the product photos for the current design.

    Lead Time: Full-Size Semi-Shelf housings currently have an estimated 4–6 week lead time.

    Fitment & Features

    Because each MP5 receiver is individually welded, minor file-to-fit adjustment may be required to achieve proper fitment.

    • Semi-Shelf LS5: Includes multiple inserts to accommodate varying shelf heights.
    • Full-Size LS5: Includes a 50D buffer designed to short-stroke the bolt carrier and help prevent hammer override.
    • Empty Weight: 6.2 oz.
