Hey guys I recently purchased a Baikal mp 18 , 12gauge shotgun and the employee of the store told me that it has a fixed choke.
Needless to say I was just excited to get it for such a good price and did not bother to thoroughly inspect the gun. It was 100$$. Now I thought a fixed choke is a cylinder bore but when I arrived home I discovered that that was not the case with this shotgun.
The barrel opening was slightly smaller than my other shotgun which was a cylinder bore.

Here are the pictures.

I was thinking its a improved choke. What do you guys think?
 
take it out and shoot it with various loads and let us know how it patterns .choke is the restriction compared to the inside diameter of the barrel so it is a somewhat useless exercise to measure the end of the barrel . i have fixed choke guns and they run the range of full, modified to cylinder . fixed means you have one choke and the only way to change it is to modify the barrel either the end or the inside of the barrel.have fun with the new gun .

Pick yourself up a cheap caliper, then phone a gunsmith nearbye and ask what the inside diameter (I.D) of each size of choke is. Put your caliper inside the muzzle and there you will have it! Pretty hard to tell with the naked eye looking at a ruler.

Have fun!

My only concern is honestly shooting slugs trough it.
I have been reading up on this and a lot of people are said that they see absolutely no problem with shooting slugs trough chokes. Even trough a full choke. The only concern I found was regarding sabot slugs, other than that rifled slugs are fine to shoot trough any choke. Is there any truth to that?

Thank you for the replies guys

Sabot slugs require either a rifled barrel or rifled choke tube for stability, neither of which has a constriction.

Foster type slugs are good in choked barrels.

Your shotgun should have choke marking on the barrel, either with letters or with asterisks. Though I am not familiar with the Saiga.

Yes, I figured that out after a little bit of researching lol, the barrel says 12gauge 2 3/4 F.
I'm guessing the F stands for full choke?
 
Another excellent chart DILLIGAF.

On my Boito shotgun the markings are "Y's " instead of *'s . The markings would normally be on the underside of the barrel, you may have to take the barrel's off to see them.

IC - improved cylinder
M - modified
IM - improved modified
F - full
 
What's your ruler say? My eyes are not as young as they were, so is it 1 3/4? or 1 7/8"? Anyhow, do a google search to change it to decimals. If I remember correctly a 12ga Full was about 695 thousandths of an inch. Or if a dime (10 cent piece) fits less than half way down the bore, it's a Full choke.
