STINC Just Bullpupped Your Krink - The o”ST”-14 Groza Kit
Luke C. speaks to Ian at GunCon 2026 to check out the o"ST"-14 Groza kit from the boys over at Stuff & Things Inc (STINC), a drop-in bullpup conversion that turns a PSA Krink (AK-74U pattern pistol) into a reasonably obtainable version of the Russian OTs-14 Groza. STINC says their conversion kit has compatibility with the 300 BLK, 7.62x39, and 5.56 Krink variants, with some fitting work potentially needed on other AK platforms.
The kit includes the iconic carry handle with a built-in rear sight (notch and post or peep aperture, both adjustable for 100 and 200 yards), plus a forward grip module with an installed trigger and trigger guard. It's a dimensionally accurate take on the real Groza using simplified machining and assembly, finished in black phosphate with all metal construction. Ian also takes some time to show off their newest project - the 5-7-9 lower, which promises to be compatible with virtually any caliber upper as long as it's a mil-spec AR-15 pattern.

Have to ask - where do you put your support hand? That barrel shroud looks like it will get hot fast and the muzzle blast on your hand wont be pleasant.
Just say no.
