Brownells 75th Anniversary - A Shooting Heritage

Only the Parts You Need, Without the Waste

The AR-15 Gun Builder's Lower Parts Kit from Fire For Effect contains all the necessary, standard small parts you need to complete a stripped lower receiver or refurbish an old rifle. It leaves out the main parts folks actually want to customize, the pistol grip, trigger, hammer, disconnector, and triggerguard.

Here’s exactly what the Fire For Effect AR-15 Gun Builder's Lower Parts Kit contains:

  • Pivot/takedown pins
  • 2x Takedown pin detent
  • 2x Takedown pin detent spring
  • Bolt catch
  • Bolt catch plunger
  • Bolt catch spring & pin
  • Buffer retainer & spring
  • 2x Hammer/trigger pins (.153")
  • Magazine release button
  • Magazine catch & spring
  • Safety selector
  • Selector detent

While many "lower parts kits" contain the whole shebang - the "fiddly bits" AND a mil-spec fire control system and Plain Jane A2 grip - the Fire For Effect AR-15 Gun Builder's Lower Parts Kit lets you buy only the parts you’ll actually install in your rifle. And the money you save? We’re sure you can find something to spend it on!
