The Silverback SRS-A2 Sport 16” is our licensed version of the Desert Tech Scout Recon Stealth A2 bullpup sniper rifle, latest model of the SRS line.   The SRS monolithic receiver, made of aeronautical grade aluminium, by CNC, features the new patented barrel mount by Desert Tech, that more uniformly clamps onto the barrel and reduces peak stress points. SRS-A2 receivers are highly lightened, participating actively to the mass reduction. Each receiver has a unique engraved serial number. The lightweight fiber glass reinforced handguard is using MLOK attachment system. SRS A2 receiver features a stainless-steel attachment point for tripod (1/4-20 UNC thread). SRS A2 receiver is compatible with the replica of the Desert Tech monopod (patented). Top rail is detachable , allowing use of multiple optional alternatives, including M2 type rails.   SRS bolt air displacement is 41 cc, it can accept any APS 13 mm springs. Stock spring type and muzzle energy may differ from one country to another, please check directly with your retailer. The cylinder is made of stainless steel (23.8 mm bore), and the monolithic bolt handle is made of steel, equipped with M8 bolt knob. The piston has an aeronautical grade aluminium body and head, a steel piston end, and a 70° synthetic rubber piston cup. The spring guide is made of fiber glass reinforced Nylon, it’s equipped with 2 dampening orings. The bolt dust cover is perforated, and the red piston is acting as a priming indicator.   The piston sear is made of steel, and the aluminium trigger is adjustable in preload. The trigger housing is made of fiber glass reinforced Nylon. The piston sear height can be adjusted by moving the trigger box forward or backward. The steel safety is ambidextrous.   Outer barrel (CNC, aeronautical grade aluminium) has a bull profile, and it’s threaded (M24x1 thread, compatible with DTSS silencers). Inner barrel is stabilized by 3 barrel spacers. Inner barrel (6.05 x 420 mm, brass) and hop-up rubber (silicone 60°) are of AEG type.   The two-way CNC aluminium hop-up unit, directly attached to the quick-change barrel assembly, is allowing barrel switch in seconds while keeping your hop up setting. Hop up setting is done by two screws on top of the rifle, through the receiver, with the provided key, without removing the barrel. Hop-up can alternatively be used with two larger setting screws at the cost of quick-change keeping hop setting ability.   Stock and butt pad extensions (two included) are made of fiberglass reinforced Nylon.   Lightweight polymer magazine has a 25 rounds capacity (60 grams). This magazine introduces a new screw-less design, allowing quick tool-less disassembly for cleaning.   No zinc alloy, all screws are in 10.9 steel.   Colors available: Black/FDE/OD. Minimum length: 691 mm. Mass without magazine: 2.240 Kg.   Black: SBA-BLT-14BK FDE: SBA-BLT-14FDE OD: SBA-BLT-14OD
