The TacFire Advantage: Precision and Performance for Your AR-10

When constructing a firearm, reliability and precision are paramount. The TacFire AR-10 Lower Parts Kit is engineered with these principles in mind. Here's why it stands out as a recommended option for your build:

• Optimized for AR-10: Unlike generic kits, this product is specifically designed for the AR-10 platform. This means that parts like the takedown pins, bolt catch, and buffer retainer are appropriately sized and dimensioned for the larger AR-10 receiver, preventing common fitment issues encountered when trying to adapt AR-15 components.

• Do all lower parts kits come with a pistol grip?
  Most lower parts kits include a basic pistol grip, typically an A2-style. However, some "minus" kits omit the grip, and others, like this TacFire kit, feature an upgraded or specific grip like the PGAR-B. Always check the product description to confirm what's included.
• What tools do I need to install an AR-10 LPK?
  At a minimum, you'll need a set of roll pin punches (especially 1/16", 5/32", and 3/32"), a small hammer (brass or polymer is best), and a lower receiver vise block or bench block. Other helpful tools include masking tape (to protect your receiver's finish), a small pair of pliers, and lubricant.
• How long does it take to install an LPK?
  For a first-time builder, it can take anywhere from 1 to 3 hours, depending on familiarity and patience. Experienced builders can often complete the task in 30 minutes to an hour. Taking your time is more important than rushing.
• Can I upgrade individual components from an LPK later?
  Yes, absolutely! The modular nature of the AR platform means you can easily upgrade components like the trigger group, safety selector, or pistol grip later if you desire a different feel or enhanced performance.
