The crush washer will crush but make sure you time it correctly otherwise if you go too far, you can’t go back as the crush washer will then be too loose.
As for the barrel protruding not allowing the brake to go on, is the muzzle device for 338? Is it not possible to use just a 762 muzzle device? |

The taper adapter simply "converts" the tapered barrel to be used with non-tapered muzzle devices. The taper adapter "creates" a 90-degree shoulder for those MD's - in your case, you would actually, slightly, lose thread area in using a SIG SRD MD. We need to confirm the part number MD you have. Assuming it is threading on correctly, you should have: SRD-338-58X24-B - but, please confirm that. EDIT: I can see in one of your last posted pics that this is the MD you have. No, the crush washer will not close that gap you are showing. Two Things may be in play here: 1) It appears you have the wrong size/diameter crush washer. That's an easy fix. 2) Your SRD MD may be out of spec. Im still up in the air on this one, as I need more info. Is there anyway you can re-install on your rifle, remove the brake portion of the brake - leaving only the base portion - then take pictures looking down inside the break/end of the muzzle? |

You have the wrong MD (I know, it can be confusing - see my first sentence ) You have a 5/8x24 threaded MD for a 338 rifle. This is why the threads in your smaller caliber rifles are protruding through the mount. You can use a standard 5/8x24 threaded 762 mount with the 338 can - this is the mount you need.

Thank you! I finally was able to order one because of you! I double checked the site still said they had stock and placed the order.
Now we wait and see if Sig plays the same game they played after I ordered an in-stock 11.5 upper in May 2021... They were in stock, I ordered online, was charged, and my order was converted to a backorder with no ETA that I eventually cancelled. |

Worse than any DI AR-15 I’ve ever fired with a can. That thing will be going down the road. |

From what I've seen, it's the latch itself on the right side. The Sig has one, the others do not. I don't know whether the larger handles on the G will help at all.
Now, if I'm shooting unsuppressed like a heathen, then any handle is fine. |
