ERATAC KeyMod Adapter – Push Button or HK – KeyMod Adapter for Push Button or HK Sling Attachment
An adapter is only useful if it connects the correct interface.
The ERATAC KeyMod Adapter – Push Button or HK is an ERATAC KeyMod sling adapter. It is used to create sling attachment points for push-button swivels or HK snap hooks on KeyMod handguards.
This product is not an optics mount and not a universal part. It is crucial that your handguard actually uses KeyMod and that the accessory makes mechanical and ergonomic sense in the chosen position.
Important note for classification:
Before purchasing, check: genuine KeyMod interface, accessory type, screw/nut plate fit, desired position, sling routing, hand position, and clearance to barrel, gas block, suppressor, or light.
What makes this product technically special:
✔ Milled ERATAC design: According to ERATAC, M-LOK/KeyMod accessories are made of high-strength aluminum and hard-anodized.
✔ KeyMod direct mount: reduces unnecessary intermediate adapters if the platform fits.
✔ No loose components by system logic: important for small rail and sling adapters on the handguard.
✔ Freedom of position: Accessories can be placed where hand position, balance, and access are sensible.
✔ Variants: Size: push button, HK – transverse grooves, sling adapter, or specific attachment type differ significantly.
Why this product?
This adapter exists because modern handguards do not automatically come with Picatinny rails or sling swivels. KeyMod saves weight and bulk, but requires an adapter in the right place if traditional accessories are to be used.
-
Connect interface cleanly: no makeshift solutions with wrong screws or improvised clamps.
-
Choose position freely: accessories are placed where you genuinely want to operate or stress them.
-
Control weight: create Picatinny only where it is needed.
-
Improve sling routing: place the sling point so that the weapon can be carried without interfering with the shooting stance.
Instructor Tip: Test adapter position with equipment before tightening
Don't permanently install the adapter on an empty table. Include the sling, bipod, gloves, light, and your shooting stance. Only then will you see if the position truly works.
For sling points, pay special attention: Does the sling pull the weapon flat against your body, or does it tilt away? Does the adapter interfere with your support hand? Can the sling touch the bolt catch, charging handle, or a light?
Our assessment
The ERATAC KeyMod Adapter – Push Button or HK is useful if you want to specifically expand an existing KeyMod setup with Picatinny or sling functionality. It is less useful if your weapon already has a better direct mount or if you choose the wrong interface.
Useful for:
- KeyMod handguards needing accessory mounts
- Range and training weapons with changing accessories
- Hunting or sporting long guns with clean sling routing
- Setups where only short Picatinny sections are required
Less useful for:
- Weapons without a KeyMod interface
- Users who already have a direct Picatinny rail on their rifle
- Accessories that require a different mount or higher load capacity
- Positions where the adapter interferes with hand position or barrel/gas block clearance
Direct Classification:
✔ ERATAC KeyMod Adapter – Push Button or HK: correct choice if exactly KeyMod needs to be adapted for the desired accessory function.
✔ Direct accessories without an adapter: better if the light, grip, or bipod are directly available for M-LOK/KeyMod.
An adapter is only good if it doesn't add unnecessary bulk and doesn't worsen operation.
Application scenarios
-
Range: short Picatinny sections for bipods, hand stops, or accessories.
-
Hunting: sensibly place sling points or accessory positions on the handguard.
-
Training: quickly compare sling routing and accessories between setups.
-
Workbench: continue to use existing Picatinny accessories on M-LOK/KeyMod.
Practical Tip: Check screws after short use
Small adapters are located in highly dynamic areas. After the first shots and after the first transport, check whether screws and nut plates are still tight.
Use appropriate tools and do not overtighten screws. Especially on handguard interfaces, damaged threads can quickly become more expensive than the adapter itself.

FAQ
Does the adapter fit every weapon?
No. It only fits weapons or handguards with a compatible KeyMod interface and sufficient space at the desired position.
Is this an optics mount?
No. This is an accessory or sling adapter. For scopes or red dots, you need a suitable optics mount.
What should I pay attention to with sling adapters?
The sling must run cleanly under tension, must not block any controls, and should not tip the weapon unfavorably.
Why not use Picatinny directly on the entire handguard?
Because short adapters can reduce weight, bulk, and sharp edges. Only using Picatinny where it is needed is often more sensible.
When is the adapter not useful?
If the interface does not fit, if the accessory is directly available for M-LOK/KeyMod, or if the position worsens your hand position and operation.
Conclusion: The ERATAC KeyMod Adapter – Push Button or HK is a useful interface component if KeyMod and the accessory function truly match. The benefit does not arise from the adapter alone, but from its correct position in the setup.
