I have both those knobs mounted on different 457's. Both will work. It's a matter of personal taste. FWIW, I find the finger grove design and overall fit and finish on the A419 knob slightly better than the DIP product. The finger groove works well IF you learn to use use your pointer finger ( vs grabbing with whole hand) to run the bolt. The DIP feels bigger in hand though. Also FWIW, I think the Little Bertha knob from Anarchy Outdoors to be the best in all respects.

Could you elaborate a bit more ? Thanks

 

I have the DIP Executive and I find it to be the perfect size. I didn't like the knurled finish on the 419 knob. The smooth finish of the DIP works better for me. It rotates in the hand better. I hope that makes sense to you.

 

I also have the DIP Executive and like it very much. Will be ordering another one for my recently bought 2nd 457 MTR..

Hope this helps....

I have the area 419 and I like it a lot . I never worked the other ones to know the difference. But it is very easy to use with just one finger.

 

I have the 419 on a 457 VPT and really like it a lot. In fact I probably will buy another one to go on my Varmint model.

 

Thanks for all the replies . Seems like they are both quality products .

looking through the responses, I think the DIP executive II would be the right choice for me , as I'm using this rifle to teach my 7 year old kid to shoot and while his fingers are still a bit too short to use the finger groove , he could benefit from the additional leverage to help close the bolt. I also considered the DIP big "Juan" knob but felt it would be comically large on such a small rifle .

If it were just me using this CZ 457 scout, I might tend towards the 419 or the anarchy knob.

... still haven't pressed the "Buy" button though , so my final decision might change

Thanks again !

 

Area 419 also, easy one finger bolt operation.

 

Know anyone with a lathe? Make your own…kingwood with brass insert.

I'd probably end up improvizing a lathe using my drill press . Might yet do this one of these days.

Thanks for the idea.

 

The Little Bertha is kind of a stretched out version of the A419. It gives you a finger grove for comfort but also gives you extra length for better leverage/ easier throw on tight bolts. It's longer than the other two mentioned. ( More Leverage might be good for a youngster?) It also has some assertive but a easy on the hand knurling . Lastly, I feel the fit and finish is allot better than the DIP and slightly better than the A419. Of the 6 different bolt knobs I've purchased for my CZ's, the AA is my favorite ( and most expensive). Your needs/wants may vary.

A friend has the 419 knob on his 457 VPC and it feels very good to me. I have the Big Juan on my 457 VPC and love it.

I would be happy with either of these.

I bet the executive 2 feels just as good, It will come down to personal preference.

 

I have put this Bergara bolt knob on a couple of czs. I really like how it feels and you can find these for about $16 if you shop around.

Could you share a link or PM me ? I couldn't find them at that price anywhere .

 

Truth be told, a chunk of old corn cobb would be better than that tiny factory ball. 🤣

 

I think every year around Christmas time generous gifts start arriving at the CZ HQ from AO, DIP, etc. with an implied understanding the OEM bolt knob will remain the same for another year as a result 🤦‍♂️

 

I've used executive 2. Happy with them.

 

Another vote for the 419 knob though in truth there's nothing wrong with any of the options in this thread.

 

Ordered the DIP executive II .

As others have suggested, it largely came down to personal preference ( I dislike knurling or texture on a knob that would be handled every shot) .

I might have considered the 419 knob if it came without knurling .

The AO knob seems really nice , but a bit out of place on a $350 rifle .

Thanks for all the help.

 

I like the Lumley smaller carbon fiber knob and thread adapter for a smooth knob...

 

For what it's worth, I also considered the rowe tactical knobs till I realized they were hollowed out .

I got stuck with one because it didn’t look closely enough, it was intended for my BMR. TBH it’s not so bad if you don’t look too closely at it 🤦‍♂️, it came off anyway though to make room for the Exec II - your choice

 

I have 2 457s and the both have the DIP Executive. They both function well with the right hand index finger. Have never tried the 419 knob so I have no opinion on that one. The Executive is a clean look and function.

 

Cheap and I love mine. On Amazon

Knob installed . Slightly nicked the old knob with the vice grips when removing it despite several layers of protective tape .

in any case, the DIP executive II seems to be the right choice for me . It's significantly longer than the stock CZ ball but somewhat lighter (I don't feel that makes a big difference in this application ).

It doesn't look or feel out of place on my diminutive 457 scout .

Functionally, it does make working the bolt significantly easier (at the expense of a longer distance to close / open the bolt ... but that's just physics ).

Once again, thanks for all the advice and options. I might try my hand at turning a knob or playing with some of the cheap plastic options for fun later on but am satisfied with tlmy current choice for now .

Don't feel bad, I had a rubber strip around mine and still managed to scratch my old one somehow.

Looks good!
