Ideal for New Builds, Refreshes & Spare Parts
The 7035-0011-1520 AR-15 Lower Parts Kit is ideal for:
First-time builders who need a single, all-in-one kit to finish a stripped lower.
Owners of well-worn, high-round-count ARs who want to refresh springs, pins, and controls.
Shooters who like to keep spare parts on hand for field repairs or quick fixes.
Instead of chasing individual detents, springs, and pins, you get a matching set of parts designed to work together in one package.
Consistent, Reliable Fire Control Components
A solid lower parts kit is key for a consistent trigger pull and reliable operation. With this kit, you can expect:
Standard, mil-spec style trigger feel suitable for general use, training, and defensive applications.
Robust hammer and trigger springs designed for reliable ignition with quality ammunition.
Properly sized pins and detents to keep your controls tight and positive.
For builders who want a dependable, no-nonsense fire control system, this lower parts kit hits the mark.
Perfect Foundation for Custom Triggers & Upgrades
If you plan on installing an aftermarket trigger:
You can still use most of the remaining components in this kit—mag catch, bolt catch, pins, detents, springs, selector, etc.
Drop your custom trigger in place of the included fire control parts and keep the rest as valuable spares.
This makes the 7035-0011-1520 kit a great base for both budget builds and higher-end custom projects.
Compatible with Most Mil-Spec AR-15 Lower Receivers
This AR-15 Lower Parts Kit is designed around standard AR-15 mil-spec dimensions, making it suitable for:
Most forged and billet AR-15 lowers that follow mil-spec patterns
Rifle, carbine, and pistol configurations in common calibers using a standard AR-15 lower
Always verify that your lower is mil-spec compatible, but in most cases, this kit will be a direct, drop-in solution.
Great Value for Builders & Armorers
For gunsmiths, armorers, and serious hobbyists, the 7035-0011-1520 Lower Parts Kit delivers excellent value:
One kit completes one stripped lower with all the expected control parts.
Having a few kits on hand makes it easy to support multiple builds or quickly repair a friend’s rifle.
Small parts like pins, detents, and springs are notorious for getting lost—this kit keeps everything organized and ready.
If you spend a lot of time around ARs, you’ll never regret having extra lower parts kits in your parts bin.
