PTS Syndicate EPM1-S Spring Replacement Parts Kit

The PTS Syndicate EPM1-S Spring Replacement Parts Kit is a complete replacement set for the internal spring and follower mechanism of a PTS EPM1-S mid-cap magazine. The kit contains the key parts needed to replace worn, damaged or lost components of the internal magazine mechanism without having to purchase a completely new EPM1-S magazine straight away.
The set comprises a long magazine spring, a short spring with a plastic connector, a spring guide with a screw and a PTS Enhanced Magazine Follower. This makes the kit particularly suitable for the maintenance and overhaul of heavily used EPM1-S magazines.
Spare parts for the PTS EPM1-S
The parts in this kit are specifically designed for the PTS EPM1-S. This compact mid-cap magazine uses an internal spring system to feed the BBs under tension towards the feed lips and hop-up unit.
After prolonged use, internal parts may wear out, become damaged or get lost during disassembly. With this replacement kit, the relevant components can be replaced individually, allowing a unit with an otherwise serviceable housing to be reassembled.
Long and short warehouse springs
The kit contains both a long spring and a short spring with a plastic connector. Together with the other components, these parts form the internal spring and feed mechanism of the EPM1-S magazine.
During assembly, it is important that the springs and connector are positioned correctly in the magazine. An incorrectly fitted, twisted or bent spring can disrupt the BB feed and prevent the follower from moving smoothly through the internal channel.
PTS Enhanced Magazine Follower
Also included is a PTS Enhanced Magazine Follower. The follower moves through the internal BB channel and is pushed upwards by the magazine spring as the magazine is emptied.
A properly functioning follower is essential for a reliable BB feed. Damage, dirt or incorrect assembly can cause the mechanism to move less smoothly and ultimately lead to feeding problems.
Spring guide with screw
The supplied spring guide with screw is also part of the internal spring system. As a result, the kit is not limited to just a single replacement spring, but contains several components that may be required for a complete overhaul of the spring mechanism.
This is particularly useful when an EPM1-S is fully opened up for maintenance. After all, small internal parts have a nasty habit of disappearing just when you need them during disassembly.
For maintenance and overhaul
This replacement kit can be used when an EPM1-S no longer functions correctly due to wear and tear or damage to the parts supplied. It is also useful for players who regularly dismantle and maintain their magazines to have a complete set of spare parts to hand.
However, a new spring is not automatically the solution to every feeding problem. Dirt in the BB feed channel, damaged feed lips, a problem with the hop-up unit or a poor connection between the magazine and the replica may also be factors.
Practical insights
When replacing the internal components, it is advisable to dismantle the magazine carefully and to take note of how the original components were fitted. Magazine springs, in particular, are under tension and may spring out of the housing unexpectedly if dismantled carelessly.
During the overhaul, check the internal BB channel straight away for dirt and damage. Fit the follower and springs without kinks or unwanted twists, and, once fitted, first check manually that the mechanism can move freely before filling the magazine completely with BBs.
Furthermore, use a suitable speedloader when loading an EPM1-S and do not force any BBs in when the magazine is clearly full. Applying excessive force to the internal mechanism will only serve to ensure that a new replacement kit is needed sooner rather than later.
Voor wie is de PTS Syndicate EPM1-S Spring Replacement Parts Kit geschikt?
The PTS Syndicate EPM1-S Spring Replacement Parts Kit is intended for owners of a PTS EPM1-S who wish to maintain, overhaul or repair their magazine. The kit is particularly useful when the original spring, follower, connector or spring guide is worn or damaged.
The set can also be useful as a spare parts kit for players who make intensive use of multiple EPM1-S magazines during airsoft, Speedsoft or training sessions. This means that a magazine with a casing that is otherwise still in good condition does not need to be replaced entirely straight away if an internal part is causing problems.

Common mistakes
- Do not assume that this kit is universally compatible with every M4 AEG magazine; it is designed for the PTS EPM1-S.

- Bear in mind the spring tension when opening the magazine.
- Do not allow the long magazine spring to kink or twist during assembly.
- Check that the follower can move freely through the internal BB channel after fitting.
- Do not force a large number of BBs into the magazine once the maximum loading resistance has been reached.

- If the problem persists, also check the feed lips, the BB channel and the connection between the magazine and the replica.
