#RollerDelayedBlowback

Today Luke C is back on the SHOT Show 2024 floor with Zenith Firearms to talk about their wild roller delayed rifle, the ZF-56. This new rifle combines a lot of the handling characteristics and features of the much-loved AR-15 platform with the theoretically more robust roller-delayed blowback system. The ZF-56 will be available in both 5.56 and .300 Blackout upon initial launch, and of course, that means that the ZF-56 will be compatible with all standard AR magazines.

Zenith Firearms presented their newest firearm, the ZF-56, at SHOT 2024, showcasing its integration of roller-delayed operation with AR-15-style ergonomics. The firearm represents a distinctive step forward, introducing innovations like a last round bolt hold open and ambidextrous controls. Set to become available for consumers in April, the ZF-56’s introduction is notable for merging traditional roller-delayed action with contemporary firearm technology.

Zenith Firearms has been making roller-delayed blowback firearms for a number of years now after they separated from MKE. They just announced their latest roller-delayed blowback firearm. The ZF-56 is a firearm chambered in 5.56 and appears to be a hybrid of typical roller-delayed rifles like the HK93 and an AR-15.

Ho Ho Ho it’s time for another roller delayed blowback gun. The PTR 9CT Classic is here by popular demand. The 9CT Classic features all of the original MP5 lines that you know and love without any of the modern attachments or features that are on the 9CT. In addition to the classic look and feel, the 9CT Classic will also come standard with new production 20-round metal magazines adding to its retro roller-delayed look.

Welcome everyone to the 108th edition of ‘Hot Gat or Fudd Crap?’, one of our many series here on TFB. If you’re new to the series, this is where we look at the most obscure firearms that are actually for sale and ask the question – is this Gat a sweet deal or only has a Fudd appeal?  Each week the TFB staff weighs in with their thoughts, but readers get the final say in the poll at the bottom of each article.

At the beginning of the current year, JP Enterprises teased a new 9mm pistol caliber carbine called JP-5. This is an AR-style carbine but unlike the majority of similar PCCs on the market that are direct blowback guns, the JP-5 is a roller-delayed blowback operated firearm … like the H&K MP5. This carbine is designed to combine the advantages of the roller-delayed blowback mechanism such as the low recoil impulse due to the lighter weight of reciprocating parts with the ergonomics of the AR-15. In the June 2021 edition of their BULLETin monthly newsletter, the company announced that after two years of development, the JP-5 is now available for preorder.

Welcome everyone to the 83rd edition of ‘Hot Gat or Fudd Crap?’, one of our many series here on TFB.

About a month ago, JP Enterprises published a teaser video where they showed their new pistol caliber carbine called JP-5. They’ve been designing this PCC for about two years and were planning to release it at the SHOT Show 2021, which, as you know, was canceled due to the Coronavirus pandemic. Recently, in the February edition of the JP BULLETin, the company revealed more information on this new firearm.  Let’s first watch the mentioned video then see what else is now known about the design of this new JP PCC.

When you hear roller delayed blowback, you probably think about Heckler & Koch because the G3 rifle and its derivatives such as the ever-popular MP5 are the family of firearms most known for successfully utilizing this operating mechanism. In handgun designs, this system was less successful with the only pistols using it that I am aware of being the H&K P9, Korth PRS and Korriphila pistols. Well, it looks like this system is still being experimented with in Germany and in this article we’ll take a look at German Geiger GRP roller delayed blowback pistol.

Just as Heckler & Koch reintroduced the original king of the roller-delayed blowback submachine guns – the MP5/SP5 last month Angstadt have rolled up with the next generation roller-delayed gun.

When we think of the iconic Cold War G3, we automatically think Heckler & Koch – but that wasn’t always the case. When the fledgling West German Army adopted the, now famous, roller-delayed rifle it was produced by not just H&K but another famous German arms manufacturer – Rheinmetall.

It’s time to get a little bit technical in Today’s Photo Of The Day.

The roller-locked* Heckler & Koch G3 rifles and MP5 submachine guns have become iconic weapons of the Cold War era, being used in conflicts everywhere from civil wars in Africa, to hostage rescues and counter terror operations in Europe, to anti-cartel operations in South America. The operating system of these rifles is as unique as they are, and dates back to the death throes of the Nazi regime at the end of World War II. Desperate to save their failing state, the Nazis tasked engineers with developing new weapons, and the engineers were all to happy to oblige, lest they too be handed an old rifle and sent to the front!

What do you get when you combine German inspiration with Swiss design and machining? An arguably overcomplicated, yet completely brilliant design. Designed after the Second World War, the Sturmgewher 57 is a roller-delayed blowback design with some rather interesting design items.
