The Patriot Ordnance Factory 00457 Drop-In Single-Stage Straight Trigger is a factory-ready trigger upgrade for AR-platform rifles that prioritizes durability and reliability out of the box. With a 4.5-pound draw weight and straight trigger geometry, this POF-USA trigger delivers a clean, predictable break ideal for shooters who want a dependable upgrade without gunsmithing. The entire assembly—trigger, disconnect, and hammer—is forged from American A2 steel and Nitride Heat-Treated to 70 Rockwell hardness, ensuring both corrosion resistance and long-term strength under repeated firing.
Installation is straightforward: the trigger drops into your lower receiver as a complete unit, with no additional fitting required. POF-USA engineered the housing with hard coat anodized aluminum and fitted it with signature rubber urethane feet that keep the assembly locked in place and free from rattle. Every unit includes stainless steel KNS Precision Anti-walk Pins, so you get everything needed for a secure install right out of the box.
This trigger is purpose-built for standard AR-15 lower receivers and is not compatible with DPMS 308 lowers featuring straight trigger guards or Sig 716 platform lowers. POF-USA also does not recommend this trigger for use in 9mm PCC (pistol caliber carbine) platforms. If you're running a conventional AR-15 platform and want a single-stage trigger with premium materials and proven POF reliability, this is a solid choice for hunting, range shooting, or precision work.

Frequently Asked Questions
Will this trigger work with my lower receiver?
The POF-USA 00457 is designed for standard AR-15 lower receivers. It is not compatible with DPMS 308 lowers that have straight trigger guards or Sig 716 platform lowers. If you have a standard AR-15 lower, this trigger will fit. When in doubt, verify your lower's specifications before ordering.
Is this trigger suitable for 9mm PCC (pistol caliber carbine) builds?
No. POF-USA does not recommend this trigger for use in any 9mm PCC carbine platform. If you're building a 9mm PCC, you'll need to choose a trigger specifically rated for that application.
What comes included with this trigger?
The trigger ships as a complete drop-in assembly with all necessary components installed. It also includes stainless steel KNS Precision Anti-walk Pins to secure the trigger and hammer pins, preventing them from walking out of the lower during extended use.
Do I need a gunsmith to install this trigger?
No. This is a drop-in trigger designed for quick installation by the end user. Simply remove your existing trigger group and insert this assembly into the lower receiver. The rubber urethane feet and anti-walk pins keep everything in place without additional fitting or modification.
