Building an AR-10, LR308, or SR-25 lower means tracking down a pile of tiny springs, detents, and pins that are easy to lose and annoying to source one at a time. The Strike Industries AR10 Enhanced Lower Parts Kit rolls all those essentials into one bag and swaps the plain mil-spec controls for Strike's upgraded versions, so your finished lower feels and functions a step above the average kit.
The standout piece here is the HEX Selector Switch, a 60/90-degree 3-in-1 safety that lets you set your throw to a short or standard rotation. It's a genuinely crisp, solid-feeling safety that a lot of builders end up preferring over their old mil-spec lever. You also get an enhanced bolt catch with improved grip surfaces, a Strike magazine catch and button, plus extended pivot and takedown pins that make field stripping easier without needing a punch. The whole controls package is machined cleaner and shaped smarter than what comes in a bargain LPK.
This is what Strike calls a builder's kit, which means it covers the lower essentials but leaves your fire control group, pistol grip, and trigger guard up to you. That's on purpose, since most people building a .308 already have a drop-in trigger or grip they want to run. You still get the AR hammer along with spare mil-spec trigger springs and pins in the bag, so you can freshen up an existing trigger rather than let it sit in a drawer. Every detent, detent spring, buffer retainer, and roll pin you need to finish the lower is accounted for.
Compatibility covers standard AR-10, DPMS/LR308, and SR-25 pattern lowers. Keep in mind the bolt catch is the AR-10 specific piece, so this is not an AR-15 kit. It pairs naturally with any of Strike's AR grips if you want to keep the whole build under one roof.
No, and that's by design. This is a builder's kit that leaves out the fire control group, pistol grip, and trigger guard so you can run your own drop-in trigger and grip of choice. It does include the AR hammer plus spare mil-spec trigger springs and pins if you want to refresh an existing trigger.
It fits standard AR-10, DPMS/LR308, and SR-25 pattern lower receivers. Note that Aero Precision M5 lowers have slight generational differences, and this kit is not compatible with ArmaLite AR-10 lowers. The bolt catch is the AR-10 specific part, so this won't work as an AR-15 kit.
The HEX selector is Strike's 3-in-1 safety that can be set up for either a 60-degree or 90-degree throw depending on your preference. Many builders find it crisper and more positive in action than a standard mil-spec safety. It comes with two levers and the necessary screws so you can configure it ambidextrously.
Yes. Beyond the standard springs and detents you'd expect in any LPK, it includes Strike's enhanced controls like the reshaped bolt catch, upgraded magazine release, extended pins, and the HEX selector. The result is a lower that looks cleaner and functions a notch above a plain-Jane parts kit at a similar price point.
