Questions & Answers
ARE THESE COMPLETE UPPERS COMPATIBLE WITH ANY MIL SPEC LOWER? (THE POF 308 UPPER SPECIFIES THEIR LOWER ONLY). I WOULD LIKE TO USE THIS WITH A DPMS.

I want to know if the POF USA Complete P-415 Edge Upper (5.56) is truly "complete" and can drop into any AR-15/M4 Lowers, or do I need to buy anything else to allow it to drop-in and shoot?

Yes, the POF USA Complete P-415 Edge Upper Receiver operates off an adjustable gas piston system.

flawless upper by LBSVAG, Verified Owner, June 11, 2021

What A Difference by R10T, Verified Owner, August 20, 2025
I got tired of constantly cleaning the carbon out of my bcg. So I decided to try this piston system. POF were one of the pioneers in this realm so I gave them the nod and bought the 16.5 inch. I really am shocked at the difference. After 500 roun...

Product Info for POF USA Complete P-415 Edge 16.5 in Barrel 5.56x45mm NATO Upper Receiver

If you need AR15 Upper Receivers to help you finish your AR build, the P-415 Edge Upper Receiver Assembly was designed to be unstoppable in all environments. Originally developed over 15 years ago, POF USA has been constantly testing, upgrading, and improving the design to perfect it. The P-415 features the E2 Extraction Technology for easy cycling during repeated fire. It also has complete ambidextrous fire controls to cater to both right- and left-hand dominant shooters, ensuring everyone can use it comfortably.image

Aside from the free-floating handrail, POF has also made many other improvements to reduce the weight of the P-415, such as their all new handguard, which reduces the size by nearly 20%. This results in a final width of only 1.75 inches, allowing you to maneuver it throught tight spaces.

The P-415 is available in both 5.56x45mm NATO and .300 AAC Blackout, and you can get it in a variety of lengths for either a pistol or rifle build. The available lengths are 9 inches, 10.5 inches, and 14.5 inches, giving you the chance to customize the final product to your exact needs and specifications.
