This is a POM nozzle with double O-rings for Classic Army and D-Boys SCAR series rifles made by Core. The O-ring stops air from leaking between the cylinder head and nozzle, stock nozzles lack this O-ring and sometimes fit so poorly a lot of air can leak. This O-ring seal can increase FPS quite a lot depending on how much air is leaking. Since this doesn't put any more stress on the motor this won't affect your rate of fire like a stiffer spring or spring spacer. The double O-rings in this design not only provides a perfect seal but also trap a pocket of grease which keeps the O-rings lubricated at all times.
All boneyard items are no returns and no warranty of any kind!
These are being sold as boneyard because on many cylinder heads they are too tight to move smoothly. These would be a good choice if you have a cylinder head with an abnormally small nozzle tube or if you need an odd length you can sand the O-rings down just a hair to get the perfect fit.
