This premium ELG (Enhanced Longitudinal Grind) lower parts kit is designed to give you true mil-spec reliability with a noticeably smoother trigger pull, making it ideal for builders who want more than just a basic LPK.
Whether you’re finishing your first rifle or upgrading a workhorse lower, this complete kit provides all the small parts and fire control group you need, including an upgraded metal trigger guard for a clean, rugged finish.
Enhanced Longitudinal Grind (ELG) Trigger – Smoother Than Standard Mil-Spec
At the heart of this kit is the ELG trigger group. ELG stands for Enhanced Longitudinal Grind—a process where the trigger is ground and machined in line with the direction of pull along its long axis.
This special grind and finish give you:
A smoother, less gritty trigger pull right out of the box
A cleaner contact surface that makes an excellent starting point for a trigger job or polish
An overall trigger feel that’s a noticeable step up from basic, rough mil-spec units
If you want a mil-spec style trigger that doesn’t feel like sandpaper, this ELG kit is built for you.
Complete AR-15 Lower Parts Kit – With Metal Trigger Guard
The 7035-0009-1520 AR-15 Lower Parts Kit is a complete LPK designed to finish out a stripped AR-15 lower (buffer tube/stock and receiver extension sold separately). Retailers list it as a “Complete Lower Parts Kit w/ Metal Trigger Guard”, giving you a tougher, more refined guard than basic polymer.
Typical contents include all the critical small parts you expect in a full kit, such as:
ELG Fire Control Group
Controls & Retainers
Safety selector, detent & spring
Magazine catch, mag catch spring & release button
Bolt catch, plunger, roll pin & spring
Takedown and pivot pins with detents & springs
Buffer retainer pin & spring
Trigger Guard & Hardware
(Some configurations may or may not include a pistol grip; always check your specific seller’s contents list.)
Everything is engineered around standard AR-15 mil-spec geometry, so it’s ready to drop into most forged or billet lowers that follow the mil-spec pattern.
Durable, Phosphate-Coated Mil-Spec Style Components
Unbranded AR / ZRODelta’s ELG series parts are known for quality materials and finishes. Listings highlight that all black parts in the kit use a phosphate coating, not black oxide, to better resist rust and wear.
That means you get:
Corrosion-resistant small parts built for hard use and adverse conditions
A consistent matte black appearance that matches most AR receivers and accessories
Long service life for training, duty, and high-round-count builds
This kit is designed to meet or exceed mil-spec performance while adding a more refined trigger feel.
