Here is a rifle built with our new MILLED SIDEFOLD Receiver. Both trunions are machined into receiver. All that is required for installation of the rear folding stock is the insertion of the hinge pin. All other work has already been done for you by FIRING LINE!!
This is our long muzzle break made from solid 4140 steel, hollowed out like the original AK74su short break. We use this break to make the short barrel Rifle a legal 16 inches in barrel length, so our customers living in states where SBR rifles are prohibited can enjoy a 74su and still stay within their state laws.

These are photos of an RPK 74 on a Russian VEPR Receiver.
Although this is not an MLS99 receiver, this rifle was built by Mike here at Firing Line.


Our newest project. A Krink in 5.54 x 39 Full Auto (for Law Enforcement Only)with a Bulgarian Special Ops Tac. Light, with a folding stock (which utilizes our NEW UNDERFOLD Receiver in 5.45 x 39)
This is one of our projects here at the Firing Line. It is a Full-Auto rifle built for law enforcement using one of our NEW underfold receivers in 762x39.
We hope you enjoy these pictures. We will periodically be changing these, so please check back from time to time and see our newest photos. Again, these are not all the applications that can be accomplished using the MLS99, so please contact us with any questions you might have.
