The product was a very nice silver finish. As well with the components attached.
It fit perfectly into my m28. And i have probably put 200 rounds through it and still going strong. It did increase my FPS and Joel count. Shooting with .45 gram bbs, was hitting the targets right on the money. Very happy with this purchase.
IS a bit of a struggle to get it completely sealed. But once everything was aligned correctly. Made it possible to complete the seal.
