I think someone needs to really look into this. The Firearms Blog called it an R4 RGP, but according to the website above, the R4 is DI, and it's the R5 RGP. As far as I can tell, that's the difference between the R4 and the R5. But then again, I haven't really looked that into it. --Funkychinaman (talk) 10:05, 3 December 2015 (EST)
The first photo is not an R4. I checked the Remington brochure and its foregrip is similar to Colt's. Ominae (talk) 02:49, 8 December 2015 (EST)
Yes, which is why I cited TFB above, but they're the only site that lists it as an R4 RGP, so they could be mistaken. As for the foregrip issue, it's all modular. --Funkychinaman (talk) 10:16, 8 December 2015 (EST)
I don't think anyone is disputing whether or not that's an RGP, but is it an R4 or an R5? --Funkychinaman (talk) 10:38, 8 December 2015 (EST)
This site is calling it yet another thing, a R4GP. I don't think we can rely on blogs. For now, I think it's safety to go to the horse's mouth, in this case, the Remington Defense catalog. I can't post a download link, so just go here and download on your own, Pages 6 and 8. It looks like only the R5 has a gas piston. --Funkychinaman (talk) 10:37, 8 December 2015 (EST)
So what's the verdict? I'm in favor of renaming this page to R5. Better to do it now while the weapon only appears on one page rather than wait until later for there to be a dozen or more pages to change with it. Spartan198 (talk) 23:24, 22 May 2016 (EDT)
It looks like the top image was also an R5 RGP, the R4 doesn't seem to have the same angular upper. Here's a pic of a basic R4 from Remington's site, it looks like a pretty standard railed M4 upper:
Granted Remington needs to fire whoever wrote that page for not knowing how to spell "muzzle brake," but still. Evil Tim (talk) 12:34, 30 May 2018 (EDT)
