223 Bob Sled Project

Starting a new 223 Bob Sled Design this morning.

This is my modded Bob Sled.

How about a CZ 527 221FB milled from a block

A few minutes later.

You're going to print it?

Yes.

 

[urbanrifleman]

It works perfectly. Going to tweak it to make it fit better. I am also going to make it longer.

 

[Gabe22BR]

Longer for ???
Flush fit would be nicer … yes???

Easier to grab like a mag.

Easier to grab like a mag.

Agree. Would save having to put a finger in the ejection port and push while trying to hold the mag release.
I've had to do that a few times.

Right????

Mine always just fell- out holding the mag button…????
I’m no machinist either ….

I see your point.

There are some tolerances in play with M5 bottom metals. The Bob Sled (at least the ones I have) is usually on the plus side and fits rather snugly. Most of my rifles won't let them drop free.

This is also very light. Much lighter than a solid aluminum block

 

[urbanrifleman]

Done!

Brad did you make it so the case head sits a touch lower than the bullet end of the cartridge? It appears you have.
That helps feeding IMHO. My 308/6.5 AI Bob Sled has that but my older 223 for the XTC game the slot has no drop angle.
Nice work !

Definitely sits so it pops a wheelie up the ramp.

I mean this sucker goes STRAIGHT into the dead center of that chamber. I went WHOA when I put the first round in. The old one I had with the hand made divot was good, but this version is even better.

So, are you going to sell them?

Sure. Why not?
