Because of the nature of the AR parts business and varying pressures of commercially available ammunition, Wilson Combat cannot guarantee function in customer built AR rifles. We recommend all components be installed by a competent rifle-smith. If you assemble a firearm with Wilson Combat components and it fails to function, you first need to check the fit of the barrel to the gas block and the overall condition of your rifles gas system/bolt carrier group to ensure your system isnt leaking gas. As buffers and springs play a role in overall reliability, the use of an aftermarket style buffer system is not recommended. When using an adjustable gas block, reliability is best achieved at the fully open setting without any gas port restriction. Wilson Combat will not troubleshoot customer built firearms/uppers. If you feel a Wilson Combat component is defective, please return the component only to us using our Return Form. Shipping to Wilson Combat is the responsibility of the consumer. |
