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

What's included (typical):

Verify exact contents on product details page.

Why a complete LPK?
For AR-15 builders who want STANDARD trigger functionality (vs aftermarket trigger). Standard GI triggers work fine for: 1) Plinking/range use. 2) Budget builds. 3) Builds where premium trigger isn't the priority. 4) Rifles that may get aftermarket trigger upgraded later.

Vs Without Trigger Group ($27.99)?
Complete LPK ($29.99): includes standard trigger, $2 more. Without Trigger ($27.99): saves cost if you're installing aftermarket trigger separately. $2 difference, pick complete if you want everything in one kit.

Build context:
AR-15 lower receivers ship as STRIPPED LOWERS, just the receiver, no parts. The lower parts kit assembles into the receiver, creating a functional lower assembly. Combined with upper receiver and stock = complete rifle. Lower parts kits are essential for any AR-15 build.

"AR-15/M-16", what does that mean?
The kit fits BOTH AR-15 (semi-auto civilian) AND M-16 (military full-auto) lower receivers. The receivers share most lower parts dimensions. Civilian AR-15 owners use only the AR-15-applicable parts.

Best for:
AR-15 builders wanting complete lower parts in one purchase. Standard GI trigger users. Budget-conscious builders. Replacement parts inventory for multi-rifle owners.
