| Hey guys, I have a SPARC that when I use the lower 1/3 co-witness mount it is rock solid. However, if I use just the high mount to get absolute co-witness, then then is a considerable amount of wiggle between the optic and the mount. I have tried to use both the long screws and the short screws with the same results. Also, I am not sure if the threads are messed up or what in one of the holes in the optic itself, but the screw goes about 1/8" then just stops. |

Call the customer service number. They'll take care of you. I had the same issue. Luckily I had several SPARCs lying around and could swap out parts to narrow it down.
At first, it seemed like the holes in the base were milled out too deep, or the screws were too long and bottoming out. When they sent me a new base and screws, there was a size of screw in the box that didn't match anything else I owned (and I have about a dozen SPARCs). |
