The CMMG Mk57: A 5.7 upper that works CMMG continues on the 5.7×28 revival path. Last year, we reviewed CMMG’s FiveSeven magazine compatible 5.7×28 Banshee. Further reinforcing the 5.7×28 revival is CMMG’s new Mk57 Upper Conversion kit for [Read More…]
In recent months we’ve seen something of a resurgence of the 5.7x28mm round with a host of new platforms chambering it. Another manufacturer offering an affordable 5.7 platform is Excel Arms, out of Ontario, California, with their X-5.7 pistol and rifle. The X-5.7 [Read More…]

Arming the Space Force, the sixth and newest branch of the United States Armed Forces will be an interesting endeavor when it comes to small arms. Naturally, any conventional weapon will be at the Space Force’s disposal while on Earth, but space brings a whole host of [Read More…]

It might be premature to say that FN Herstal’s 5.7x28mm cartridge (“5.7”) is experiencing a renaissance, but the cartridge has done something that most proprietary-ish, specialized calibers don’t do: Bask in increased popularity decades after its introduction. [Read More…]
What do you get when you take the venerable speedster 7.62 Tokarev, and load it with a muzzleloader-style sabot and 50gr .22 cal projectile? You get one of the most interesting pistol, submachine gun, and personal defense weapon ammunition concepts there is! Today [Read More…]
It has been a little while since we visited the subject of modern personal defense weapon calibers, so to start it off again we’ll be taking a look at a new high velocity round that is only a few years old: Armscor’s .22 TCM. This round was reportedly [Read More…]
I have no doubt that the majority of our readers know about SAAMI (Sporting Arms and Ammunition Manufacturers’ Institute), which sets the ammunition standards, cartridge and chamber drawings etc. These standards are guidelines for manufacturers, but many [Read More…]

The FN Five-seveN pistol is chambered for the same 5.7x28mm cartridge as the famous P90 PDW, but the short barrel of the pistol results in less velocity.

On one hand, you have people making ludicrously grandiose claims about its effectiveness, while others simply write it off as a gimmick or overpriced .22WMR from Belgium. A long time ago I wrote the PS90 off as a pointless, but fun rifle (having [Read More…]
Anthony Williams, small arms theorist and co-author of the book Assault Rifle with Maxim Popenker, wrote an article in February of 2006 on the development of the Personal Defense Weapon and its ammunition, which he amended in late 2013. He includes in the article two [Read More…]
If there ever was a gun that you could use as the poster-child of being aesthetically odd, the P90 and its semi auto counterpart, the PS90 certainly would be very strong candidates. The bullpup design of FN Herstal’s P90 make it look like a science fiction [Read More…]
