Just copped my grail gun. CQB mod 2 with a poverty pony lower, maybe even more rare than the upper now.

•Jan 11, 2026Sup dudes, just wanted to come on here and say that SFM magwells are in fact NOT compatible with SR15 lowers. I also have an HRF, and it technically fits, but not perfectly. There's substantial bend on the backside of the magwell. Anyone know any brands that make a flared magwell specifically for SR15 lowers?

•Dec 13, 2025Hey everyone- have been wanting a KAC rifle in 5.56 for the longest time and see that the KS series is getting close (maybe?) and wondering what everyone’s thoughts are on the best setup for someone in California would be? An equally important question would be how to obtain them also lol Looking at the new line, it looks like the KS3 upper would be CA legal, and then pair it to an LMT lower? Or pinning a KS2. Calling around, no one has them yet and no preorders open that I could find. Wonderi...
