About DPMS

DPMS is an established American firearms parts manufacturer specializing in AR-15 platform parts and accessories. Their lower parts kits and repair kits are widely used by AR-15 builders, gunsmiths, and rifle owners for assembly, maintenance, and repair work. DPMS parts meet standard AR-15 dimensional specifications and work with most AR-15 lower receivers.

AR-15 Parts Quick Reference

• STRIPPED LOWER, AR-15 receiver with no internal parts. Requires lower parts kit to function.
• LOWER PARTS KIT (LPK), All small parts that go INSIDE the lower receiver. Typically includes trigger group, springs, pins, detents.
• LPK WITHOUT TRIGGER, Same as LPK but no trigger parts. For builders using aftermarket trigger.
• REPAIR KIT, Replacement small parts for maintenance/wear/loss. Different from build LPK.

Build workflow: Stripped lower + Lower parts kit + Upper assembly + Stock = Complete AR-15 rifle.

Important: Legal Compliance

AR-15 lower parts kits and repair kits are firearm accessories, NOT firearms themselves. They are not regulated as firearms and do not require special licensing in most jurisdictions. The COMPLETE LOWER RECEIVER (stripped or assembled) IS the regulated firearm component requiring transfer through licensed dealer.

Customers are responsible for compliance with all federal, state, and local firearm laws. Some states/jurisdictions restrict certain parts (e.g., bump stocks, certain triggers, magazine capacities). Verify local regulations before purchase.

Frequently Asked Questions

Why "without trigger"?
Many AR-15 builders install AFTERMARKET triggers (Geissele, ALG, Timney, Larue, etc.) instead of GI/standard triggers. Buying a full lower parts kit + aftermarket trigger means you have unused trigger parts. The "without trigger" version saves money for builders going aftermarket trigger from the start.

What's included (typical):
Hammer/trigger PINS (but NOT trigger or hammer themselves), magazine catch + spring + button, bolt catch + spring + plunger, takedown/pivot pins + detents + springs, safety selector + detent + spring, buffer retainer + spring, pistol grip + screw. Verify exact contents on product details page.

Vs Full Lower Parts Kit ($29.99)?
Without trigger ($27.99): for builders adding aftermarket trigger separately. Full LPK ($29.99): for builds using standard GI trigger or budget trigger replacement. $2 difference, pick by your trigger plans.

Build context:
AR-15 lower receivers ship as STRIPPED LOWERS, just the receiver, no parts. You assemble lower parts (this kit) into the receiver to make a functional lower assembly. Then add upper receiver and stock to complete the rifle. Standard AR-15 builder workflow.

Best for:
AR-15 builders installing aftermarket triggers. Trigger upgrade projects (replace GI with premium trigger). Multiple-build projects where you want unified lower parts source.
