This expert-level guide details the field stripping and reassembly process for the FN FS2000 bullpup rifle, presented by Karl Kasarda of InRangeTV. It covers safety checks, magazine removal, accessing the fire control group, separating receivers, disassembling and reassembling the bolt carrier group, and cleaning the gas system. The guide emphasizes the unique forward-ejection system and potential complexities in disassembly, advising caution with certain components.

Quick Summary

Field stripping the FN FS2000 requires ensuring the rifle is unloaded, removing the magazine, opening the top receiver cover, cocking the hammer, and then removing the fire control group. The upper and lower receivers are separated by a cross-bolt, allowing access to the bolt carrier group and gas transfer rod for further disassembly.

Frequently Asked Questions

How do you field strip the FN FS2000?

Field stripping the FN FS2000 involves ensuring it's unloaded, removing the magazine, opening the top 'toilet seat cover,' cocking the hammer, removing the fire control group, separating the upper and lower receivers, and then removing the bolt carrier group and gas transfer rod. Reassembly follows in reverse.

What are the key components of the FS2000's bolt carrier group?

The FS2000's bolt carrier group includes a gas transfer rod that drives the carrier, a firing pin, a cam pin, and a unique polymer lifter that handles spent cases and acts as an out-of-battery safety device.

What is the ejection system of the FN FS2000?

The FN FS2000 features an innovative forward-ejecting system. Spent casings are moved by a polymer lifter and ejected out of the front of the rifle, contributing to its ambidextrous design.

Are there any specific warnings when disassembling the FS2000 bolt carrier group?

Yes, it is strongly advised not to disassemble the polymer lifter from the recoil spring. Improper reassembly can break the polymer arm, disabling the ejection system and rendering the firearm inoperable, with parts being difficult to find.
