Lambda Defence GHM9 GBB SD Conversion Kit – Black

Lambda Defence GHM9-SD Conversion Kit
Do you want to take your PDW GHM9 GBB to the next level and give it a clean carbine-style appearance? Would you like to increase performance by installing a longer inner barrel but have nowhere to hide it? Are you looking to improve ergonomics and weight balance of the replica? This SD conversion kit from Lambda Defence replaces the original short handguard with a complete aircraft-grade aluminum set consisting of a threaded outer barrel, a long suppressor with official B a T GHM9-SD markings, and an extended M-LOK handguard. The result is not only a more aggressive look, but also more space for accessories and improved ergonomics. The kit is designed to fit GHM9 Gen1 and Gen2, so you don’t need to worry about your replica version.
