It looks to me like a Ruger 10-22 carbine action and barrel with a Magpul stock.
It could be a Kidd action, but probably not because you wouldn't have to change the trigger.
IMO, Kidd triggers are about as good as you can buy.
Looks like the stock has two spacers in the butt to lengthen the stock length.
That is great if you have long arms. I use spacers on my adjustable stocks for that reason.
If you don't have long arms, it could create too long a pull for you.
One of my shorter buddies literally can't shoot my rifles comfortably and has to fight the stock length to get into shooting position. One just can't be consistent in setting up if the stock doesn't fit.
You didn't say what ammo you were shooting.
It does make a difference.
If it was match ammo from a rest, not too good.
If if was cheap ammo from a rest (maybe with quoted muzzle velocities over 1200 -1250 fps) not so bad.
If you were shooting off-hand or without a front rest and rear bag, pretty good.
Remember, no matter how you were shooting, you are just getting used to the rifle and the trigger.
A .22LR rifle is light and easily muscled.
Your groups look to me like you might have been moving around some, either in and out on the scope and/or changing your set up between shots.
A very small change in set up position will open up groups - that is not the rifle but "shooter induced variation".
All of my 10-22s shoot best with match ammo - CCI Std Velocity, SK Std Plus and Rifle Match shoot well and are moderately priced, by today's standards.
SK Rifle Match shoots slightly better but the accuracy depends on the lot.
Lot-to-lot variation can be significant in lower cost and even moderate cost ammos.
You paying a lot more for premium match ammos with expensive quality control processes. But I have seen the difference in accuracy, especially at 100 yards.
My best group averages have been with Lapua Center-X and Midas Plus but they are pretty pricey. Lapua X-Act is in another league both in accuracy and price.
High cost Eley (Tenex and Match) shoot best in tight chambers.
They are quality tested with Anschutz actions.
Semi-autos, almost by definition, don't have tight chambers.
I have two bolt-actions that shoot Eley extremely well, but in my 10-22s or even my Kidd the high cost Eley ammos are a waste of money.
Most other Eley ammos are not so chamber sensitive - Edge shoots well in my 10-22s.
Norma Match shoots slightly better than Norma Tactical.
Enjoy experimenting with your new rifle.
Hopefully you will be able to buy enough different ammos to find what your rifle will shoot best.
As you get more comfortable with it, I have no doubt that your groups sizes will get smaller.
