S.H.I. - R.A.C. Personal Defense Weapon

The Solani Heavy Industries R.A.C. PDW was developed in the mid-2080s as a yet further extension of the R-XXX Series Rifles that SHI had been mass-producing by that point- but a more revolutionary extension in comparison to the simple re-chambers and gas system/receiver modifications done to the R-208 platform so far.

The R.A.C. is a truly innovative design, miniaturizing the R-XXX series' vectored recoil system and improving the compact weapon's short-stroke piston to be more reliable in addition to modifying said piston to help reduce recoil even further.

As such, the R.A.C. is extremely lightweight and compact, but at the same time highly accurate, with less vertical recoil and tighter shot groupings than comparable rifle-derived SMGs and PDWs.

However, the R.A.C.'s name is in relation to what truly sets it apart- Rifle, Advanced Cartridge.

6.3x35mm X-SAP

The R.A.C.'s custom PDW cartridge, 6.3x35mm eXperimental Sabot Armor Penetrator, or X-SAP, is a short-length bottlenecked round with a sabot-style bullet armed with a tungsten-titanium alloy tip, enabling both high muzzle velocity from a short barrel and a high degree of body and plate armor penetration. However, this cartridge is particularly straining on the operation of a standard rifle, so the R.A.C. was specially developed to handle the extra strain from the high-pressure propellant load used in each X-SAP cartridge while not degrading weapon performance or reliability.

The 6.3mm rounds are also significantly more compact than the R-208 standard load of 7.4x38mm, leading to a standard 30-round magazine for the R.A.C. being far shorter in length than a comparable dual-stack R-208 mag.
