- description
M-LOK handguards are slim and light precisely because they carry no rail. That is exactly what you want until you need to mount something that only comes with a Picatinny clamp - a light, a laser, a bipod, a foregrip.
The ERS bolts into the M-LOK slots and gives you a run of 20mm rail exactly where the accessory needs to sit. Three lengths cover the range from a single small mount to a long section for a light and a switch together, and PTS build them properly rather than as a stamped afterthought.
The point of M-LOK is only adding weight where it earns its place. Fit the length you need and no more.

Good to know before you buy
For M-LOK handguards only - these will not fit KeyMod or plain handguards. Choose the shortest length that carries your accessory; the whole reason to run M-LOK is not carrying rail you are not using.
Frequently asked questions
Will these fit KeyMod?
No. They are cut for M-LOK slots. KeyMod uses a different fixing entirely.
Which length do I need?
3 slot for a single small mount, 9 or 11 slot for a light and a pressure switch, or a longer accessory. Measure your accessory's clamp before choosing.
Is the mounting hardware included?
Check the product images for what is supplied, or ask us before ordering.
Can I fit more than one?
Yes - most builds run one or two, positioned where the accessories actually go.
