Taurus is getting into the subgun game with the new RPC. This gun features roller-delayed operation, complete with interchangeable locking pieces.

It accepts all standard AR-15 pistol grips. The top of the gun has a full-length picatinny rail, and there are MLOK slots on the handguard as well for accessory mounting. It feeds from a proprietary polymer magazine holding 32 rounds. Taurus also offers 20 and ten-round options. Interestingly, the instruction manual states that a 110-degree locking piece (that bears a resemblance to H&K ones) comes installed for use with standard ammo, and an included 85-degree locking piece should be swapped in for subsonic or suppressed use. This new design also includes ambi controls and a last round bolt hold open, unlike many legacy roller-delayed designs.Taurus offers two primary versions of the RPC, one with a Strike Industries arm brace, and one without. Each of those versions is also available with a 10-round magazine in lieu of the standard 32-rounder for people who live in places that prohibit such things. MSRP for the non-brace model is $939, and $1,099 with the brace. All images from Taurus. From the manufacturer:"The RPC blends proven ergonomics with modern capability, thanks to its roller-delayed operating system that both enhances reliability and reduces felt recoil. The aluminum construction trims weight while maintaining duty-grade durability. Controls are fully ambidextrous, with the bolt release/lock and magazine release easily reached from both sides, and a reversible, non-reciprocating charging handle that adapts to the shooter, not the other way around.The full-length Picatinny top rail provides space for optics and enablers, while the M-LOK handguard allows users to set up the platform to fit their needs. A 4.5” threaded barrel comes standard, and the quick-change barrel system adds flexibility for different configurations in the future. Available with or without a Strike Industries FSA folding brace, the rear of the receiver features a vertical Picatinny rail for attachments."
