Lambda Defense SR2M GBB Airsoft SMG - Brown

Lambda Defence SR2M GBB SMG

Are you looking for a maximum realism gas blowback SMG SR-2 with a steel construction? Do you want a compact GBB replica that is ideal for CQB while offering authentic controls? Do you care about detailed workmanship, strong blowback and a modern PDW design? Then the SR2M GBB by Lambda Defence is exactly what you are looking for. This replica is based on the Russian SMG SR-2 and features a machined steel body, steel top cover, upward-folding stock, and a folding front grip. Thanks to the gas system, it delivers a highly realistic shooting experience with noticeable recoil and natural weapon handling. Base performance with a 174 mm inner barrel is 95 m/s (0.9 Joule) using Green Gas and 0.20 g BBs, ensuring safe compliance with CQB field limits. You can also purchase SR-2 accessories such as a suppressor, side RIS rails, or a top RIS rail for a red dot sight. The replica comes in an exclusive box in Russian colors with Cyrillic descriptions. From the factory, the gun is preserved in oil — we recommend wiping off excess oil after unboxing and leaving only a light oil film on moving parts. The ambidextrous fire selector works in the AK-style, allowing you to choose semi or full-auto fire. In terms of quality, materials, and overall impression, this is one of the finest replicas of Russian weapons available. The side and top RIS rails shown in the manufacturer’s photos are not included and must be purchased separately.

Warning

• The magazine is designed only for medium-power gases such as Green Gas, e.g. Nuprol 1.0 and 2.0.
• Using stronger gases (Red Gas / Black Gas) may damage magazine seals and internal parts; such damage is not covered by warranty due to excessive stress.
• After purchase, we recommend thoroughly cleaning excess lubricant around the nozzle, hop-up chamber, and trigger group. Then lightly lubricate moving parts and seals with quality silicone oil. If unsure, see our guide.
• Oil or lubricant must not enter the hop-up chamber or BBs in the magazine, otherwise range and accuracy will be reduced.
• After cleaning, it is necessary to activate / slightly adjust hop-up pressure, otherwise BBs may fall straight through the barrel.
• The replica must be regularly lubricated with silicone oil (seals, moving parts, trigger mechanism).
• Side and top RIS rails shown in illustrative photos are not included. These must be purchased separately.
