Frequently Asked Questions

What are the key design changes in the AK-50's front trunnion?

The AK-50's front trunnion has been redesigned with modified top geometry to prevent bolt carrier interference. It also features a threaded barrel hole for precise headspacing and deeper rivet chamfers to accommodate a thicker stamped receiver.

How does the AK-50's new bolt carrier improve prototyping?

The AK-50's bolt carrier now incorporates a modular cam groove design, inspired by the Stribog. This allows for easier prototyping of different cam paths without needing to machine entire new bolt carriers for each iteration.

What changes are being made to the AK-50's recoil system?

The AK-50 is moving from a dual-spring to a single-spring recoil system to save space and prevent binding. A booster spring is included in the rear trunnion to manage high-pressure loads or suppressed fire.

What type of rivets are being used for the AK-50 build?

Brandon Herrera is using oversized PKM-style rivets for the AK-50 build. This choice is intended to provide enhanced structural integrity for the firearm.
