AR-15 – Lower Parts Kit – Single-Stage Trigger – Black
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
Spike’s Tactical built this standard AR-15 lower parts kit for builders who want a clean one-box lower completion setup with the trigger group already included. It is the straightforward answer for finishing a stripped AR-15 lower without piecing together springs, pins, and controls from five different places and then wondering why one detent vanished into the shadow realm.
Fitment
- Fits standard AR-15 pattern lower receivers
- For .223 Remington / 5.56 NATO AR-15 builds
- Rounded hammer is listed for use across AR-15 caliber builds using standard AR-15 lower geometry
Does NOT fit
- Not for AR-10 / LR-308 platforms
- Not for proprietary receivers that do not use standard AR-15 lower parts geometry
- Not the right choice for buyers specifically wanting an upgraded ambi or enhanced trigger kit
What it does
This kit gives the buyer the core lower receiver parts needed to complete a standard AR-15 lower, including the fire control group, safety selector, bolt catch parts, magazine catch parts, trigger guard, and A2 pistol grip. It is the plain, dependable route for a normal build.
Why it’s worth it
This is the sensible middle lane. It is more complete than a no-trigger kit, less expensive than the enhanced package, and gives a builder a standard single-stage trigger setup without turning the project into a scavenger hunt.

Install notes
This is a standard lower parts kit, but “standard” does not mean foolproof. Install carefully, especially around detents, springs, and the trigger guard roll pin, unless you enjoy turning a simple build into a floor-scanning exercise.
Verify before you buy
Verify your receiver is a standard AR-15 lower and verify that you want a standard trigger-included kit rather than a no-trigger setup or an enhanced kit with upgraded controls.
