#HK91

Welcome back to another edition of The Rimfire Report! This ongoing series is all about the rimfire firearm world and its various guns, ammo, sports, and mysteries. Today we have a sort of guest article from Nicholas C and his HK91 conversion kit to shoot .22LR. According to the HK fans, this was another form of training for the German military. The alternative was blue training plastic ammo but that is for another time and article. Let’s dive into this .22LR conversion kit for the HK91.

Timnney Triggers is offering 10 lucky people the chance to become beta testers for its latest offering. Timney Triggers is offering up a replacement trigger for Heckler & Koch and PTR HK91-type rifle platforms. The HK91 Replacement Trigger looks to be a drop-in style trigger as with many of Timney’s triggers so installation should be easy and function should be on the same level after beta testing.

Let’s take a trip back in team to December 1984. Just before SHOT Show, Heckler & Koch USA advertised the models HK91A2 and HK93A2 for $399 each. The deal was: “At Rock-Bottom prices you will never see again.”

The title of this review should actually read: The PTR Industries K3P R PDW – How The U.S. Government Forced Me To Buy A Battle Rifle. Ok, forced is a probably too strong of a word. But you see, I’ve been waiting for a transfer approval from the ATF National Firearms Division for a 9mm MP5SD for over a year and a half (Form 3 and Form 4 approvals). And since I had no roller delayed action guns to satisfy my HK craving, I went in search for the near opposite kin to the SD – a short barreled .308 battle rifle. My journey ended with the PTR Industries K3P pistol.

Alton C. is a guest writer for TFB and has contributed a number of articles in the past.

With the increased popularity of the Heckler & Koch SP5K and other HK-patterned roller delayed firearms, I thought it might be a good idea to demystify some of the basic mechanics and maintenance that new owners might face from time to time. So when my new faux four position trigger group for an update to my PTR Industries K3P PDW (G3K) showed up with a 9mm ejector and 9mm hammer spring, I decided to learn about HK trigger groups in a “gunsmithing for dummies” kind of way.

You can now get more modern with your HK91, HK33, and clones of those rifles with M-LOK and KEYMOD handguards. Whether you have GI variants, carbine length, or rifle length, there are now handguards out there that open up a Pandora’s box of accessories to you.

In October, I traveled out to see my co-writer Alex C. to collect data on the weights of different long guns and some of their components. Over that weekend, I weighed 58 rifles and submachine guns, and numerous magazines, bolts, bolt carriers, and other miscellaneous items. The purpose of this was not only to collate a general list of the weights of different weapons, but to be able to enhance the accuracy of a previous spreadsheet I’d produced showing the loaded “combat” weights of different rifles; that being available at this link.
