- Aluminium construction
- For front wired/external battery M4/AR15 AEGs
- Modification to the receiver required - Experts only!
If you need your M4/AR15 AEG to be as short and light as possible it can only benefit from adding a 1913/20mm Picatinny Stock Adapter from 5KU! This adapter allows 1913/20mm Picatinny stocks, such as those used on the legendary Sig MCX and MPX, to be mounted in place of the standard M4/AR15 buffer tube, though it will require modification to mount to most M4/AR15 AEGs, and is only recommended for experienced users with some fabrication skills!
This adapter is ideal for front-wired M4/AR15 variants and can be used with rear wired setups but with additional modifications to the adapter to allow the wiring to come through. If you have the cojones to take a saw to your M4, and you have the need for a more compact, ergonomic and flexible setup you can't go wrong with this stock adapter!

Special Instructions
To mount this adapter you will need to cut the receiver extension which mounts the standard AR buffer tube down in most cases. This requires careful measuring and precision, so if you are not confident you can carry out this modification successfully we do not recommend attempting it.
Use of this adapter is limited to front wired M4/AR15 AEGs unless modifications are made to the adapter to allow for the wiring of a rear wired M4/AR15 to pass through. This modification is only recommended for advanced users, and if such modifications are attempted we can no longer accept returns on the adapter.
