Talking Lead 516 – Blowback! New Bearing Delay System: MEAN Arms

In this episode of the Talking Lead Podcast our special guest is David Lucas with MEAN LLC: Blowback! When it comes to shooting pistol caliber carbines (PCC) the key to a smooth, comfortable, reliable shooting experience is managing the blowback from the gas. Over the years there have been many engineers and companies that have tried to tame the blowback lion with radial cuts, flywheels, toggles, vectors, rollers and more. Enter the Bearing Delay System by MEAN ARMS. MEAN Arms has developed a new innovative take on the 9mm delay blowback design using ball bearings. Lefty and David also talk about MEAN’s Hybrid triggers, Hybrid handguards, ENDOMAGS and their new EXOMAGS

The heart of MEAN Arms Bearing Delay Upper Receiver is the unique ball bearing bolt carrier group (BCG). The ball bearings interface with corresponding features in the barrel extension and provide the lockup in battery and the delay after firing. The system can be tuned by replacing a “Lifter” to change the angle of the surfaces that push the bearings from the inside of the BCG. The bolt face includes a unique center ejector to provide the most consistent ejection of any 9mm AR on the market. With 3 bearings allowing 50% more contact surface area than a traditional roller delay. This means that even with the higher pressures of modern ammunition, the Bearing Delay system has greater durability than any roller delay.
