Building or upgrading an AR-15? The Strike Industries Enhanced Lower Parts Kit with Trigger gives you a complete fire control solution without starting from scratch. This kit bundles all the essential lower receiver components you need for an AR build—trigger, hammer, springs, pins, and support hardware—letting you focus on the upper receiver and furniture rather than hunting down individual parts. It's purpose-built for shooters who want quality internals without the piecemeal hassle.
The trigger is the heart of the kit. Strike Industries engineered it to deliver a crisp pull weight between 4.5 and 5.5 pounds with noticeably smooth take-up and break. The sear engagement surfaces are longitudinally ground and polished, and the sear angle is precision-cut to eliminate creep and binding. That attention to detail translates to better trigger control at the range or in the field—without compromising the safety margins you expect from a mil-spec-compatible trigger.
Whether you're assembling your first AR or refreshing an older build with modern internals, this kit covers the lower receiver trigger assembly and lets you retain full control over caliber, barrel length, and handguard choices. Note that it does not include a grip; you'll source that separately to match your preference and hand size.
| Brand | Strike Industries |
| Product Type | AR-15 Lower Parts Kit with Trigger |
| Trigger Pull Weight | 4.5–5.5 lbs |
| Compatibility | AR-15 (mil-spec) |
| What's Included | Fire control group, trigger, hammer, springs, pins, and lower receiver hardware (grip not included) |
Yes. The Strike Industries Enhanced Lower Parts Kit is designed for mil-spec AR-15 receivers, which is the standard across most manufacturers and aftermarket lowers.
The kit does not include a pistol grip. You'll need to source and install your preferred grip separately.
Absolutely. This kit simplifies lower assembly by bundling all the small parts and fire control components you need in one package. You'll still need to select your upper receiver, barrel, handguard, and grip, but the trigger assembly work is handled.
Strike Industries polished the sear engagement surfaces and cut the sear angle to precision tolerances. This manufacturing reduces friction and binding in the trigger mechanism, resulting in a crisper, cleaner break without any mushy or gritty feel.
