LCS Air Arms SK-19 Automatic .25 Air Rifle

New to the air gun hobby purchased several other rifles and for a beginner this was the easiest to zero. Out of the box mounted scope set on target bulls eye one shot on target made the adjustment the next round hid dead center. Trigger easily mastered, what a dream. If you are just starting I would recommend saving thousands working your way and just start here. Only wish is a removable magazine cpop in and out for quick reload.

First off it looks amazing, I’ve only fired about 400 rounds thus far. FX slugs grouped reasonably well, crow mags were all over, don’t have a chronograph yet so getting the right setting for the projectile is a lot of trial and error. Loading the gun is somewhat cumbersome. The only real problem that I have run into so far is that most pellets and slugs fit loosely in the magazine, the action of the rifle jostles the pellets around and I’ve had the skirt get pinched between rear of magazine and receiver, causing a “jam” also noticed some are moving forward and wearing on front of projectile. I need to find a bullet that fits snugly.

Quite an engineering feat. The whole issue is run by air. Handling-nicely well balanced; accuracy-incredible;
Full auto; fun. Triger critized; but very light takup and clear, crisp tho light let off. A good trigger which most firarms users would envy. The first shot after reloading or idle for a while has a stiffer trigger let off, and no takeup. Reloading; slow and can be painful. There are 2 ways this rifle can bite you when reloading. The reloading lever on the left can snap down on our left middle finger as you roload. Hold it up with your left hand until finished reloading. And if you rotate the mazagine with your left fingers at the top it can pinch you as it rotates clockwise and catch you between the frame and magazine. If you use your left hand to help rotate it, keep it on the lower portion of the mag. These things made me say a bad word.
Best consistancy between 150 and 250 bar. I get about 50 shots. Is it worth it? You bet! This rifle will give you lots of fun on targets, tin cans or on the hunt with slugs.

Hmm where do I start. Currently on Month 3 and absolutely love this Rifle, great for hunting small game, super easy to load just takes a few times to get used to the magazine. Which some people think this isn’t a weakness I do not. Having owned other airguns with lame plastic based nonsense that jams up or breaks super easy is beyond annoying. Lcs magazine is made from titanium and hasn’t jammed or created any flyers in my watch. Build quality is top notch at this price range as most pcp’s are. I recommend getting a moderator with this I personally use the Donnyfl Emperor and it does quiet it down some. I’m going to try getting the extension for it which I here does wonders.

I would say the downside not really manual hand pump friendly, A little loud out of the box but not terrible and you will love this gun so much you better budget 3-4 x the amount u usually buy.

I've had this rifle for a couple of months & I like it but there are some things I had to get use to.First off,loading is different & you better pay attention to what you're doing.If you forget to close the cylinder unlock lever & shoot it then it'll become locked in that position. I was able to call AOA & they guided me on the fix.I guess I'm still getting use to the trigger.It's not bad but in semi auto I have accidentally had a few double/triple taps. but I believe that was on me because I usually shoot this & my Sumatra at the range & the triggers have a different pull respectively.I've had good success with the JSB King 33.95 heavies & the Hades,the Benjamin Domes were ok with tweeking.Couldn't get ANY slugs to shoot well at ANY velocity.Used the FX pocket chrony to track speed.Cleaning the barrel was no problem but I did have an air leak issue & sent it back.AOA fixed the problem & I got it back in a timely manner.I also bought the dual bottle adapter with a extra bottle but can't comment on how much more shots I can get with this because I shoot tethered at the range but I'm sure when I shoot in the field it'll be better than a single bottle.I have ran the Hades near 1100fps but don't shoot them at that speed.AT about 890-900fps I get near hole in hole but haven't shot them past 25yrd,that's the max at the indoor range.
Overall I really like this riffle,it shoots very well,(but I still shoot my Sumatra 2500 a little better),& I can say that the more I shoot it the better I shoot,OH & did I mention HOW MUCH FUN it is to shoot it semi or full auto,just carry a ton of ammo.

I got pretty much the same results as antonyudin but I didn't test as many slugs. They only problem with this gun is the amount of ammo you use. My gun is rock solid super reliable easy to clean, adjust. The trigger isn't first-rate but it isn't bad either. I'm using Nielson slugs 38.5 grain @ 960fps. I also have tried the lighter slugs 33.5-36.2-29.026.8-29.5 they will fly over 1000fps. I haven't finished my home range close then I can get some numbers and pics of the consistency. I tried a 0DB moderator not sure it did anything. I like the sound of it outside. I have yet to crank it all the way up. Not one jam or problem. Full auto is silly. :)

The power was set at about 50 clicks down from the max.
