They sent it in a wooden box, the wood stock dismantled. i was quite upset with the condition of the gun, it was a used one. i can see clear tear n wear on wood stock, they just applied a new layer of thick wood polish. barrel and chamber recently 'blue'd. looks like was a showroom display unit. regardless, it is perfectly working condition. but entire metal parts were sunk in oil..
I made a risky move for further investigation, decided to dis-assemble the unit. i read earlier posts about the "spring blast' so did it in a controlled environment. Maaaan, it was stain all over.. But spring was in good condition (BTW, SDB 2000 spring is aweseome they are exact quality of Diana magnum guns). i could see the chamber inner wall full of black thick oil.. SDB 2000 piston is pure stainless steel. i cleaned everything with a tissue towel, and immediately took to a gunsmith and asked him to aseemble it back

after th cleaning and aseembly i tried 10 shots on shooting target, got 9 of themin .5 inch group. thats perfect. gun is very accurate and delivery is cool. power is excellent. Tried shots on 1/2 inch hardwood with very low qyality pellets, it penetrates halfway thru the hardwood.. thats good. usually i dont see pellets completely submerse to a dry hardwood.
Overall, SDB 2000is an excellent gun. it has power and accuracy out of the box. (Well my case is different.) The trigger is WAY smooth, exactly like precihole. With my AK agni 500 i have to trigger @ 5-6 kg pressure, but with SDB 2000 its only 1.5 kg pressure. so trigger is a breeze. Yes, their trigger system is something similar to Diana (not exact like in diana)
Do i recommend SDB 2000 over other indian .22 air rifles ? VERY MUCH. but dont buy from that kolkata dealer..i am not publishing his details here, if anyone want to know, PM me with ur email id, i will let you know.
Side note : my purchase was a bargain deal. i got it 20% cheaper than market price.
I cant upload photos here, i am new.
