The BR-15B was designed as a response to customer demand for a single-shot lower receiver. It was machined from 7075 aluminum billet, which provides a 70 percent increase in strength when compared with other lower receivers forged from 6061 aluminum alloy. In addition, the design removes the magwell and incorporates an oversized, integrated trigger guard which increases the strength of the receiver. This tough, durable lower also comes with an upper tensioning screw for a snug fit.
The BR-15B Billet Single Shot Lower Receiver from Zel Custom can be bought stripped without the trigger group, magazine release, selector, or bolt release for $199. There is also a completed lower option which comes with a Magpul PRS Stock, Zel Custom M/P Adapter, Pachmayr Large Field Pad, DPMS Buffer Tube and DPMS Lower Parts Kit. Retail price for this version is $599. The completed lower can also be upgraded with a Timney Trigger. This upgrade costs $874. According to Zel Custom’s official website, this item is currently out of stock. They are accepting orders for back-order, which are expected to resume shipping in May 2014.
