Description
EMG Helios x Noveske x Double Eagle M4/N4 MWS Bolt Stop Plate (G101)
This is a replacement bolt stop plate for the EMG Helios x Noveske x Double Eagle M4/N4 MWS series gas blowback rifles, part of the G101 series. It is intended to replace a worn or damaged plate or to keep in your parts box so that a small failure does not end your game day.
The EMG Helios x Noveske N4 by Double Eagle is a licensed gas blowback M4 that replicates the Tokyo Marui MWS system, running on green gas and taking Tokyo Marui ZET-compatible magazines. Because it follows the MWS layout, it benefits from a wide range of parts and accessories.
Why keep a spare
Gas blowback rifles put real mechanical stress on their parts, because the bolt slams back and forth with every shot. Parts around the bolt and bolt stop take a lot of that wear, especially with heavy use, cold-weather play or high-flow gas. Having the correct replacement on hand means you can fix a problem quickly rather than waiting for parts to arrive.
Using the correct part for your rifle’s series also avoids the fitting issues that can come with generic or third-party parts.
Fitting
Fitting a bolt stop plate involves partially stripping the rifle’s lower receiver, so it should be carried out by someone familiar with GBBR internals.

Compatibility
Designed for the EMG Helios x Noveske x Double Eagle M4/N4 MWS series (G101). It may not fit other MWS-pattern rifles, so check your rifle’s model and series before ordering.
Care and maintenance
Before fitting, clean the area around the part and inspect neighbouring components for wear. Use a suitable gas blowback lubricant on moving parts as recommended by the manufacturer, and avoid getting oil on the hop-up rubber or inside the barrel.
Keep spare parts in a sealed bag or parts box so they stay clean and are easy to find. After fitting, test the rifle with a few rounds and check that everything cycles smoothly before taking it to a game.
