Art it is crucial, and proven to be a problem

So I finally got my shim kit in. Used the 2 thinnest shims to get the front band tightened up and timed to 530. I can see the problem/ gap referred to with the break and the crown but I'm still confused at the shimming between the break and barrel.....so I'm not gonna mess with it.

So instead of my messing with shims and stuff and potentially spacing the gas system out too much I'll keep it simple.

DOES THE DELTA P RECTIFY THIS?

In the advertisement/description it says that it registers against the face of the barrel. Has this been confirmed?

As of now this would be my last "bolt on" accurization without stepping into a new chassis. So it would be worth it to me.

You guys warned me, and I've slipped down the rabbit hole. This is a "down the road" mod so I'm just trying to plan my steps and document progress as I go while researching.

Yes, the Delta P adapter eliminates the gap, I use it and I like the results.

Rock and roll. I'll add it to my list of things to do.

After a bunch of reading, it looks like the Delta P is worth trying.
I also cleaned up my crown. Faced with a 0* cutter

Yet it is not a problem for the M16/AR-15 type rifle, which also has a large gap between the muzzle and flash hider.

I just ordered the Delta P today.

Sure wished that I had a lathe and a mill still. If our concern for that gap is correct then a bevel on the muzzle wont be helpful and would actually be harmful.

The theory is that a gap between the muzzle and any device attached to it can create a chamber where gasses will swirl and buffet the bullet. Therefore anything that creates a space between the muzzle and the device attached to it will be a problem. A tapered muzzle will create a small void in that area. I've never tested to see if that's true but when I cleaned my muzzle up I didn't taper the muzzle, I made it flat.

When the part comes in, I’ll have to take some measurements. Looks like about 0.012 would make it flat again

I recommend trying the rifle first before you change the muzzle, if you get groups that you're happy with then don't change anything.

Did you need any additional crush washer when you went to the VG6 Brake on the delta P or did it time properly.

I have the Delta P and a VG6 Gamma coming. Tossed in a set of extra crush washers of varying thickness for $5 for a just in case. Like anything mechanical nothing is 100% identical so if rather not need them but have them on hand.

Primary Arms had the brake for a little cheaper than anywhere I could find, and ordered directly from Delta P. The Delta already shipped today.

No, I didn't add a crush washer but I did have to take a little material off of the face of the brake that contacts the Delta P adapter. I don't like to add any more parts than I need to. This is my Delta P adapter with a VG6 Epsilon brake.

Ok, thanks for the pic! I know they include a crush washer and saw it was recommended to have a few different ones on hand in case it times way off. Ill see how things look before I need with anything and likely report back. Doesn't appear you needed to remove much.

Whatever you do don't load the barrel when installing the vg6.

Doesn’t the comp mount on the Delta P?
The Delta P threads onto the barrel......right?

It does don't over torque it to get it to time

 

[faawrenchbndr]

Got ya......distortion from over torquing

 

[hodgexj1996]

Copy that. Is this similar to the gas lock where I'm shooting for a 5:30 time by hand and requiring a small amount of torque to bring it the rest of the way.
