The Retro Arms barrel spacer’s design is rather revolutionary: from the top wings that look like a mix between a rose and a hurricane latch on to the barrel and to the outer barrel/silencer’s inner walls. Thanks to its structure it goes well with inner barrels that are a little bit thicker than normal. In addition, the outer diameter also gives a little. Features: Width 32 mm Length 18 mm Weighs around 4 grams 3D printed About the compatibilities: For its size this fits any gun/silencer which has an inner diameter no higher than 32 mm and at the very least over 30 mm.
