Hey folks, sorry if this has been covered already, but I didn't see it. I recently purchased a KAC 7.62 CRS-1 suppressor and the model designation shown on the can as 600QDC/CRS-PRG. Is this normal?

First I’ve heard of it being marked “600”. Did you mean “762”?

600 was the original model number for the CRS-1, same can though.

Those were in production when we did the revision to the naming convention.
Congratulations, you have a unique piece of KAC history.

Interesting. My old CQBs are all marked “762QDC/CQB-PRG”.

Sounds like Jack is saying these are 7.62 CRS-1 models on the inside that got printed before the change from alphabet soup model names. Yours would still be the old CQB-PRG with all the other letters and numbers, not a CRS-1.

Just noticed mine says 600QDC/CRS-PRG too, pretty cool.

Great! Guess a piece of trivia for the KAC Vickers Guide... Thanks, looking forward to shooting through it.

Could Kac make their cans/products any more confusing?

@Jack_L say a guy wanted to get his hands on one of these "Model 600" cans. Can you say about how many got shipped out with that engraving?

We received some. I think I still have one or two of them kicking around. I can't remember if they're FDE or black.

These are either going to be forgotten about in 10 years, or you'll see them marked as uber rare on GB in 10 years for $10K.

Yes. Don’t give them any ideas.

I think it was a couple hundred that were in process before the realignment.

Rgr, so not impossible to find, but not a cakewalk either. Thank you!
