I bought this one about 1 month ago. I have now put over 750 rounds through it.
Hatsan Invader
Things I would change.
The trigger is atrocious this has a 8+ lb trigger pull. When I contacted Hatsan they said it needed to be like that because it is Semi-Auto, but then they also said it was a liability issue. at any rate the trigger pull is to stiff for real accurate shooting. This gun at times will load the pellet but it does not cock the gun so it won't fire, this is random so I have no idea why. When I contacted Hatson they said these barrels are tapered which was not made clear in the stats, they also said these were made for pellets not slugs, well by the time I heard back from them I had already shot slugs through it. I went through 6 different pellet makes and weights and out of all 8 the only ones that will hold a 1" group 5 rounds at 50 yds. is the JSB 33.95 Grain. which in my opinion is not great accuracy but trigger pull could effect it too. Now I shot slugs from 29 grain to 39 grain, the one that shoots the best is the Neilson 34.9 grain which give 5 shot group at 50 yds cover with a dime
Things others should know
If you are sensitive to heavy trigger pull I don't recommend this gun. If you are looking for a gun just to shoot semi-auto and accuracy is not what your after then you should do ok with it. Compared to the Hatsan Flash in the accuracy department this gun looses every time. now I can positively say this this gun will shove the 33.95 grain pellets through a 1" pine board at 50 yds. It will also put the 34.9 grain slugs through what they now call a 1" pine board at 50 yds and it will also put them through 5/8" plywood so this thing will kill I have no doubt about that according to the one pellet rifle ballistic program I could find at 50 yds it should be producing 52.37 ft.lb. of energy. Now this gun when it was shot by pyramid in 10 for 10 measure 870 fps not 900 fps at muzzle with a 20 grain pellet.
