STINC's Groza Conversion Kit Turns Budget AK Pistol into Bullpup Rifle
Stuff & Things Inc demonstrated a drop-in bullpup conversion kit at GunCon 2026 that reconfigures a PSA Krink into a functional OTs-14 Groza pattern platform. The o"ST"-14 kit performs as a reversible adapter system. No permanent alterations needed. Gun owners interested in compact, non-NFA bullpup configurations now have an affordable entry point. The PSA Krink starts around $600-$700 retail. STINC's conversion cost remains manufacturer-specified but targets the budget-conscious builder market.
Key Details
- Drop-in conversion designed for PSA Krink (AK-74U pattern pistol)
- Transforms platform into OTs-14 Groza configuration without permanent modifications
- Demonstrated at GunCon 2026 by STINC representatives
- Maintains AK-74U compatibility and ergonomic controls
- Preserves pistol-to-rifle conversion flexibility for end users
Why It Matters for Gun Owners
Bullpup rifles remain legal in most states, with California and New York implementing specific restrictions on "assault weapon" configurations. This conversion kit avoids permanent structural changes, meaning owners can revert to pistol configuration if regulations shift. For shooters in permissive states, the Groza pattern offers compact handling in a 5.45x39mm platform without Class III paperwork. Budget builders gain access to a historically significant design. The reversible nature protects your investment if politics change your state's rules.
DownRange Analysis
This kit exploits a regulatory gap smart manufacturers have been working for years. Drop-in conversions sit in gray area between pistol and short-barreled rifle definitions. Heller and Bruen emphasis individual ownership rights, but ATF guidance on "one-way" conversions remains inconsistent. Serious gun owners should verify their state's stance before purchase. The Groza pattern itself—known for reliability in compromised conditions—appeals to builders prioritizing function over AR ergonomics. STINC's approach prioritizes modularity. That's the right direction.
