In the Belly of the Beast: NEMO Omen Field Strip

Published on December 31, 2019
Duration: 9:20

This guide details the field stripping process for the NEMO Omen rifle, an AR-10 platform known for its ability to chamber .300 Win Mag. Key features highlighted include the integrated buffer system in the bolt carrier and a POF-patented roller bearing cam pin for smoother operation. The process involves separating the upper and lower receivers, removing the bolt carrier group, and then disassembling the bolt carrier group itself, including the firing pin, cam pin, and the unique integrated buffer.

Quick Summary

The NEMO Omen rifle features two key patented innovations: it was the first to chamber .300 Win Mag in a .308-sized receiver and incorporates an integrated buffer system within the bolt carrier for enhanced cushioning. Additionally, it utilizes a POF-patented roller bearing cam pin for smoother operation and reduced wear.

Frequently Asked Questions

What are the key patented features of the NEMO Omen rifle?

The NEMO Omen is known for two key patented features: it was the first rifle to chamber .300 Win Mag in a .308-sized receiver, and it utilizes an integrated buffer system within the bolt carrier for enhanced cushioning during cycling.

How does the roller bearing cam pin in the NEMO Omen improve performance?

The roller bearing cam pin, patented by POF, replaces the traditional square block cam pin. Its rounded, bearing surface significantly reduces friction and wear within the upper receiver, leading to a smoother cycling action and increased longevity.

What is the significance of the NEMO Omen chambering .300 Win Mag?

The NEMO Omen's ability to chamber .300 Win Mag rounds within a .308-sized receiver is a significant engineering feat, offering a substantial increase in ballistic performance and range without a drastically larger firearm footprint.

Can the NEMO Omen be charged from either side?

Yes, the charging handle slot on the NEMO Omen's bolt carrier is designed for ambidextrous use. This suggests that the receiver could be adapted for left-side charging if an additional slot were present on the opposite side of the receiver.
