Description
This Spike’s Tactical Lower Parts Kit does not come with a hammer, trigger, disconnector, or the two main springs for the fire control group. Instead, this LPK is meant to be paired with a drop-in trigger unit. Drop-in triggers make the assembly of your stripped lower or finished 80% lower even easier, while also upgrading your trigger, hammer, and disconnector for better performance.
This LPK includes the following (but not all) parts required to complete your lower:
- Magazine catch assembly
- Pivot and takedown pins
- Bolt catch assembly
- Pistol grip
- Safety lever
- Buffer retainer
- Trigger guard
Need help? Here’s how to install the lower parts kit.
You’ll Need an AR-15 Buffer Kit
The buffer kit includes a buffer tube, recoil spring, weighted buffer, and the latch plate and castle nut. In addition to this LPK and a drop-in trigger, these parts are all required to make your lower functional.
Finish Your AR with an Upper Assembly
Our barreled upper assemblies are put together by experts and guaranteed to function. Each assembly includes a quality AR-15 barrel, handguard that comes installed, and a mil-spec bolt carrier group and charging handle.
