This is a really well made hinge trigger system. It increases your rate of fire 3 fold. I can get off about 8 balls second or more. It is wonderful. It helps you in really sticky situations where you need a lot of fire power and good accuracy from your autococker. If you have a good barrel and this frame, you will be in good shape.
This product is hard to find. Not that many stores have products from eclipse, which has it's company based in the UK.
You should get this product. It is well made and really is a performance product. I love it. You should get one.
