Fortunately, these platforms offer an endless number of […]

Congratulations on your purchase of the modern roller-delayed blowback system-powered (MRDS) ZF-56 rifle. Smooth-shooting, accurate, reliable, and built to industry-leading tolerances and specifications, the ZF-56 is a miracle of modern roller-delayed engineering. All the same, like all firearms, the ZF-56 will benefit immensely from routine cleaning. Here’s your primer on how to administer basic cleaning to the

Our MRDS platforms offer several significant advantages over AR-style platforms. They are smooth shooting, more reliable, have no gas system, have (generally) long-lasting components, and are entirely bufferless. We could go on with that, but for the time being, we want to give the spotlight to four of the platforms we’ve developed that are built around our

With that said, as is the case for any

PCCs, or pistol-caliber carbines, are not rare. Roller-delayed PCCs, which rely on roller-delayed blowback operation as opposed to direct gas impingement, are. Most ARs and AR-style platforms use gas impingement, which requires a gas block, tube, a bolt carrier group with a gas key, and then a buffer system which consists of a tube that houses

Anyone who’s a fan of roller-delayed actions who is also interested in adding a PCC, or pistol caliber carbine to their collection, should look into our MRDS, or modern roller delayed system, as the perfect solution. Here’s your primer on our modern roller delayed PCC. Why a Pistol Caliber Carbine (PCC)? In a nutshell, a

Whether you shoot a ZF-5 or an actual HK MP 5, the truth is that these subguns are a little limited in terms of what attachments you can add, based just on the number of mounting points. The MP5 accessories and parts covered in this short post will help change that paradigm. Here are some

The HK MP5 doesn’t have much going on that could give you cause for complaint. The action is legendary and the compact footprint has proven indispensably effective in CQB encounters in the hands of law enforcement officials around the globe. Perhaps you could bemoan the price – the HK MP5 is famously expensive – but
