Battle Arms Development Enhanced Lower Parts Kit Package 3 - Premium AR-15 Upgrade Set$34.95
Availability: In Stock
The Battle Arms Enhanced Complete Lower Parts Kit in steel black delivers a thoughtfully engineered collection of investment-cast components designed to upgrade your AR-15 build beyond mil-spec baseline quality. This Battle Arms Development kit combines proven control surfaces with precision CNC and investment-cast manufacturing to give you a more robust lower receiver assembly—all without the inflated cost of full-custom shops. If you're building a rifle that needs to run reliably and feel good in your hands without breaking the bank, this kit gives you the parts to make it happen.
The standout upgrades here are purpose-driven: the Enhanced Bolt Catch uses investment-cast 8620 heat-treated steel with a manganese phosphate finish for durability at a practical price point. The single-sided Enhanced Safety Selector draws from Battle Arms' design heritage, offering diagonal serrations and mil-spec compatibility. The Enhanced Magazine Release (BAD-EMR) is CNC-machined from billet 7075-T6 aluminum with a distinctive V-shaped button face and horizontal serrations that ergonomically self-center your index finger. The included Adjustable Tactical Grip (BAD-ATG) lets you dial in your preferred angle—17, 25, or 33 degrees—with the provided hex key, so you're not locked into someone else's compromise.
The Enhanced Takedown and Pivot Pins (BAD-EPS) feature improved gripping surfaces with low-profile heads that won't interfere with ambidextrous safety operation. The kit includes everything you need: hardened stainless steel detents, nickel-plated pin springs, and a neodymium magnet to simplify assembly. You also get a mil-spec trigger and hammer assembly with nickel Teflon finish, all springs, detents, and the trigger guard roll pin—everything required for a complete lower receiver build.
Battle Arms Development has focused on the details that matter: ergonomics, material quality, and real-world usability. This isn't overcomplicated or gimmicky; it's a well-thought-out kit that works for hunters, range shooters, and builders who want their AR to feel as good as it functions.
