Eagle Vision Quick Detach MBA Thread adapter for SIGMA/HELIA Silencer

A simple, well-made QD adapter system designed to work with Eagle Vision silencers, muzzle brakes and air strippers — including the SIGMA and HELIA series. The indexed locking mechanism gives repeatable alignment so you won’t see point-of-impact shifts when you remove and refit your moderator, and the quick-detach action makes swaps or storage straightforward without upsetting zero. Construction mixes CNC-machined 6061-T6 aluminium modular sections with a stainless steel main QD coupling for longevity where it matters.
 
Choose the thread option you need: the MBA-QDB is the silencer-side QD coupling (male M23 x 1) and you can pair it with either the 1/2" UNF x 20 or the M14 x 1.25 female thread adapter to fit common airgun barrels and shrouds. The parts are light, serviceable, and supplied with sealing rings so you can fit them and be confident of alignment and seal.
