MSBS Grot: The Complete History of Poland's New Army Rifle (ad-free)
🕑 Added 2022-12-07 12:00:06 +0000 UTCThe MSBS Grot is Poland's current military service rifle, and has gone through several iterations in the many years of its development that led to its current 2nd generation form. It is best known in the US as a rifle designed to be interchangeable between standard and bullpup layout, although that capability was dropped when the Polish Army opted not to adopt it. Fundamentally, the Grot ("Arrow" or "Spear") is a short-stroke gas operated, rotating bolt, 5.56mm system derived from the AR-18 system. It spent several years tied up in bureaucratic limbo as part of Project Tytan - Poland's version of a Future Soldier program. It was finally dragged into mainstream adoption when the newly formed Polish Territorial Defense Force adopted it.
Today we will be tracing the development of the Grot form its very first mockups through the preproduction prototypes, the first generation rifle, and the now-standardized second generation - plus a look as the grenade launchers developed alongside it. I would like to give a very big thanks to Fabryka Broni in Radom, Poland for the full access they gave me to this rifle. While the teething issues the Grot had in development are typical of new rifle designs, not many companies are willing to share the whole project history, warts and all. I really appreciate that FB did!

Wish the Pole had these in Afghanistan in 2019 to try. Shot the Beryl instead. Not complaining about that but this seems like a very well thought out rifle.

the bad thing about that would be completely other places to handle the thing but... great idea. I like that. more options can hardly hurt. that sure beats two rifles. this would be changeble calibers it would sound the peak to get out one design since..? too bad about the BP not adopted. afg with the launcher seems comfy.
Arms of America is importer for WBP & I think FB. Gona call Andrew tomorrow. Probably won't get him , he not in office so much anymore. They might have a plan for the Grot.

I want one , not the bullpup

Why the gas thing need to be adjustable?

I hope those nice Polish armorers let Ian get some quality full auto range time...
Great video, thanks. Just as a note - as you correctly said in the video, but differently that it is written in the text - "grot" is "arrowhead" or "spearhead", not just "arrow" or "spear". Can't wait for the video about Błyskawica submachinegun!

Your D&A skills never cease to astonish me.

Damn. If only this type of clear, straightforward treatment with actual designer/developer input were available for AR10, AR15, AR18, SKS & the AK series. (Granted, Simonov is dead before video interviews were a thing and all those weapon developments would need MUCH longer videos. Which I'd watch every minute of). Instead of me needing to read dozens of books, watch hours and hours of video interviews with Stoner, Kalashnikov + others- and then winnow out all the apocrypha, urban legends, bureau of ordnance BS & other obfuscation as best I could. Then get the actual rifles in my hands to field strip and test fire for my own tactile verification (haven't got my mitts on a "real" AK74 yet, took me almost 40 years and too much of my income to get "hands on" with all the others on that list). Gun Jesus needs to video this, our new testament. Hallelujah! Praise the lord and pass the ammunition!!!
