A. Furnish and install one BULLET RECOVERY SYSTEM for use in forensic firearms examinations. System will enable the recovery of projectiles fired from an assortment of firearms with a maximum kinetic energy equivalent to a .338 Win. Mag. cartridge. System will fully contain water under all firing conditions. The system must be proof-tested to 13,000 ft-lbs. (50 BMG) before leaving the manufacturer. System construction will maximize safety of personnel and minimize damage to the recovered projectile. Self-contained design will incorporate all necessary components on a single, transportable structure. These components will include, but not be limited to: one-piece shooting tank; water filtration; automatic lid operation; solid-state underwater lighting; integral vacuum recovery of projectiles; and optionally, brass catcher; remote firing stand; air spring suspension of the tank; HEPA air filtration. Contractor will be required to demonstrate a fully operational system prior to shipment. Further contractor requirements include on-site training, 5-yr. tank warranty and two-year parts and labor warranty. System must be a regularly manufactured item by the vendor, with at least four prior law enforcement installations. References, literature/brochures, and photographs must accompany proposal. Proposal must address each of the requirements contained herein. Vendor must demonstrate history of performance and financial responsibility. B. The following items are to be constructed of type 304 or 316 stainless steel: Bullet recovery tank and lid, lid hinges, air filter housing, all weldments and reinforcements to the tank, all screws, bolts, nuts and washers used by the vendor in the construction of the system. NYLOK nuts are required where vibration and shock are present in mechanical fittings. Underwater lighting housing will be constructed of stainless. C. All plumbing and piping are to be constructed of stainless steel. The initial piping fittings at the tank must be stainless steel due to the strength requirements imposed by shock. D. The use of galvanized piping or fittings is prohibited. The joining or abutment of dissimilar metals that would provide conditions for galvanic corrosion is prohibited. Brass to stainless is allowed. E. Platform walkway will be constructed of aluminum checker decking. Handrails will be constructed of anodized aluminum tubing.
