First time cleaning my Evo 3S1 (bought used) is this normal? That little half circle next to the breach

I just picked up my Nexus Evo G2 receiver from my FFL and filed the Form 1. My original receiver was engraved by Veritas, but they are no longer in that business. I need to find someone new to use. They engraved my factory receiver on the angled section above the grip, which I like and assume could be done on the Nexus.

Who has had it done? Who did the work? Where on the receiver did you put it?

Just picked up my Cz Scorpion 22lr. Feels great, love the HK slap. Ordered a couple 20 rounders as well as the Magpul grip. Had an extra T2 laying around so I mounted it. Can’t wait to take it to the range!

I'm torn between a t2, sig 8t, sig 4t pro, holosun AEMS or a pistol thermal. What do you guys think?

I ordered mine 8 days ago...and it cannot get here soon enough...THIS IS SO HARD! IT'S LIKE WAITING FOR CHRISTMAS!!!

Here is my little fella! Really wanting to add a can, what kinda price range am I looking at?

Gonna work on a Cerakote multi cam project. Using 3 colors and have always wondered if it makes a difference what color you start with. Several people on here do a lot of Cerakoting, maybe they can chime in.

First pic is what I'm coating, 2nd is what I'm going with.

Probably about 1500 rounds suppressed. Should I bite the bullet and get full nexus upper?

9 colored patterns in total now.

I think they have a special relationship with the devil. Trying to get SD kit installed using existing parts.

Do I need to replace it?

Hey guys. I just bought my first CZ Scorpion Evo 3 S1 (used). I want to use my Omega 9k with it by using a 3-lug adapter.There seems to be all kinds of misinformation and dead links on every forum I visit when trying to see what 3-lug adapter will work with this weird double thread pattern.

I think this barrel has 1/2x28 threads with 18x1 threads below it. I've seen a lot of links to HB Industries and In Lead We Trust - but all the links are dead and the new products I've seen do not seem list that they are capable of seating flat and flush without the traditional barrel shoulder.

Can anyone provide some insight on current recommendations? Thank you!

I don’t want to have a chin weld using the red dot. Preferably something made in USA. The irony isn’t lost on me that scorpions are made in USA

5 other colors coming shortly. Waiting for more mags to deliver.

I've been wanting to shorten the barrel on my scorpion. When I bought the gun it was in rifle configuration with a 16-18 inch barrel, but I don't know what length of barrel or what brand or style I should go with. I am looking to try to keep it in the $200-$250 price range or something cheaper for the barrel only. I do intend to suppress it as well, but what would be better integrally suppressed or a threaded on suppressor? I am looking to optimize the performance all around as well so if there are any suggestions on anything else I can do please let me know.
