  • Give your AK the iconic look!

If you want to add some tactical trimmings to your AK an extended fire selector would be a good call. The LCT AK Fire Selector is constructed from stamped steel and is a modernised design with a ledge that can be used to select fire modes from a firing grip.

This makes a massive difference when it comes to handling an AK and allows it to go toe to toe with the AR platform in ergonomics and efficiency. It doesn't come with any fittings and is only the fire selector. A perfect item for any Tactical AK or custom AK build, this selector lever not only looks super slick but also makes your AK super slick to use. Not to mention, it will give the iconic fire selector scratch mark on your receiver!

Please note this is only the selector and does not include the necessary fittings for installation.

If your M4/AR-15 AEG is a bit scratched up, the Delta Armory Receiver Set for M4/AR-15 AEG will sort that out! This set includes the upper and lower receiver, fire selector switch and front receiver pin, available in high density polymer or alloy construction. If you're working on a lightweight build, the polymer version is ideal. If you want weight and realism, you want the metal version!

Styling-wise, this receiver set is Delta's own design, inspired by real steel "Billet" receivers found on high-end, ultra-modern real steel AR builds. The trigger guard is enlarged and built-in, improving strength when compared to milspec receiver designs, in line with the latest real steel ARs hitting the market. As we might expect, we are treated to a 20mm Picatinny receiver rail running along the top, ready for a red dot sight, scope or iron sights. 

If you're building from scratch, you will need a charging handle, magazine release, dust cover and mock rear pin to complete the receiver itself, along with your internals and pistol grip. While we can make no guarantees, parts from most other brands should fit this receiver without issues. Whether you need a bargain receiver for a scratch build or want to change the build style of an existing M4/AR-15 AEG, the Delta Armory Receiver Set for M4/AR-15 AEG will do the trick!
