Perfect addition to my 457 , much nicer than stock bolt!!

Very easy to install this bolt knob is excellant

Was as described very nice fast shipping good transaction. Would recommend this product and the seller.

Feels great. Like the size a lot better. Not too big, not too small. Just right.

The new EGW bolt fit perfectly, as expected. Removing the OEM knob was a breeze, with no issues. I feel the size is perfect for my hand and it is surprising how much it aids in bolt function from an ergonomic standpoint. This EGW bolt knob is highly recommended and the price is fantastic.

Very nice bolt knob. I'm very pleased with what I purchased and the speedy delivery. Installed the following day and shot with it today. Makes cocking and extracting much easier.

I have two of these on two different CZ 457 .22cal bolt guns and find them to be an asset to opening and closing the bolt on these two rifles. There is nothing wrong with the bolts on the two CZ rifles except that they make the bolt knobs to small for the American mrkt. I highly recomend these bolt knobs from EGW. The threads are the same size, and the knob has right handed threads, just make sure you chuck up the bolt in a vise and use a softener to grasp the knob if you use pliers to unscrew the existing knob and to screw on the new larger knob. EGW handles good quality merchandize.

Perfect

Not that it is hard to open and close the bolt, but the new knob makes it much easier and faster to work the bolt handle . Wife says it turns the rifle from an 8 to a 10 . Could not be more pleased with it . Good price and fast shipping , whats not to like . Mike

Great bolt knob! Easy to manipulate your bolt
