WHAT’S INCLUDED
- Ricochet Firearms B-AR polymer lower receiver, serial number RF00006
Ricochet Firearms produced the B-AR lower in small batches, and this example is one of the first off the line, indicated by its single-digit serial. The company’s crossed-rifles logo is molded into the left side, adding identifiable branding without extra weight.
The polymer construction reduces overall mass compared to aluminum lowers while retaining strength in critical areas. Metal reinforcement in the buffer tube threads prevents wear during stock installation and removal, addressing a common concern with polymer receivers.
A molded, squared trigger guard is integral to the design, eliminating a separate part and creating more room for gloved use. The receiver accepts standard AR-15 pattern uppers and components, and its “Cal: Multi” marking supports a wide range of calibers from .22 LR to larger bore options, depending on the upper assembly chosen.
Control layout remains familiar, with a 2-position safety selector cut, standard magazine release, and takedown pin locations matching Mil-Spec dimensions. The matte black finish blends with most commercial uppers and accessories.
