#DelayedBlowback

In 2019, TACCOM introduced a delayed blowback recoil system for 9mm AR-style pistol caliber carbines that utilizes neodymium magnets for delaying the bolt. Fast forward three years and the company has a new and improved version of this magnet delayed blowback recoil system. Let’s take a closer look.

Scheel Manufacturing is a competition-oriented firearm parts and accessories manufacturer founded by competition shooter Corey Scheel. The latest and most interesting product of this company is a roller-delayed buffer system designed to convert blowback AR-pattern pistol caliber carbines into roller-delayed blowback operated ones. The Scheel Manufacturing roller-delayed buffer system has a pair of rollers on pivoting arms built into the buffer and roller recesses cut in the buffer tube.

This new TACCOM product may look like a simple captive buffer assembly for AR-pattern firearms, however, as its name implies, this system delays the rearward motion of the reciprocating parts. The delay is achieved thanks to the use of rare-earth neodymium magnets. Let’s see how the company describes the operation of this delayed blowback recoil system:

Hill & Mac Gunworks’ flagship is their ambitious project to create an affordable, shootable reproduction of the WWII-era German StG-44, but another thing they have been working on is a recreation of the CETME-L Cold War era Spanish assault rifle. Unlike their StG, which is being made from the ground-up, the CETME-L effort centers around the use of parts kits, now available relatively inexpensively on the surplus market.

German gunmaker Korth was present at Industry Day, showing off variations on the Sky Marshal 9mm clipless revolver, and the PRS roller retarded blowback semiautomatic handgun. TFB got a chance to fire both guns, and found their triggers – as expected – to be excellent, with the PRS’s trigger being especially light.
