Excellent customer service. Inquired then bought his 22xx Crosman type aluminum breech and can only say positive on workmanship and service. Breech came with brass extended probe with a nice stainless handle. Breech also came with two set screws to hold the barrel in place. A stainless screw holds the front end of the breech and located just behind the probe so no hole snagging the pellet like the oem steel breech plus it's a lot lighter. Walked me through notching the hammer so it does not hit the screw. Highly recommended seller.
