| Devastating, authoritative knockdown power! The Sumatra 2500 is an easy-to-cock, lever-action repeater. This precharged pneumatic (PCP) has two built-in chambers (290cc total) that hold high-pressure air (3,000 psi) from a scuba tank, hand pump or compressor. It has a two-stage adjustable trigger. The sights are pretty unique, in that both the front and rear are adjustable. The front post can be adjusted for elevation by turning a small wheel under the post. The rear is a two-hole aperture that flips from a small to large hole and is adjustable for windage. Accuracy is the name of the game when it comes to shooting, and the Sumatra 2500 excels in that area: 3/8" ctc at 30 yds. with Eun Jin pellets. To get the most from this airgun, you'll want to mount a scope on the 11mm dovetails. The finely rifled (and 10x1mm threaded) steel barrel (1:18 RH twist) is fed by a 6-shot cylinder that makes for quick follow-up shots. The cylinder makes it easy to use longer pellets and even mix-and-match different pellet lengths and types. The adjustable power wheel has 13 settings, making this one of the most versatile powerhouses on the market! You'll get about 11 shots on high power and 18 on medium. Includes probe with 1/8" BSPP male threads and 2 rotary clips. A hard Plano rifle case (PL1502-01) is strongly suggested! Click on the AMMO link for a list of recommended pellets. Check the ACCESSORIES link for additional pellet cylinders, scopes, durable targets and maintenance items. | |||||||||||||||||||||||||||||||||||||||||||

Sumatra 2500 Carbine by Eun Jinreviews summary
Things I would have changed:Not much to dislike about this gun. But I will touch on those also. First and foremost are the rear peep sights. Basically they sit too low and the apertures are WAY too narrow to use. I drilled out the apertures in mine and they are now marginally usable. But I use a scope so this is not a deal breaker for me. Next is the trigger pull. It IS adjustable but only down to about 3 # which is about 1.5 # too heavy for my taste. Needs to be adjustable to a lighter pull. However, that said, it breaks clean and predictably even if a tad too heavy so it is very usable. Not near on par with an M-Rod trigger though, but everything else kicks the M-Rod to the curb! Third problem is fixable, but on high power it is an AIR HOG! Full high it gets six good shots. Each successive shot is slower than the last. With 16.1 Eun Jins doing full level 13 power at 975 fps by shot #6 you are at 900 fps and shot 12 is at 750 fps. One other thing. Get a good BIG carbon fiber tank. You WILL shoot this gun a bunch and gobble up the air. This problem is solvable by reducing the power setting. At power level 8 my 16.1 grain Eun Jins still do about 935 fps average and give me 18 good shots. At power levels of 4 - 5 with "normal" weight pellets I get about 900 fps and around 50 - 80 good shots! So save the power blasting for hunting only, and use a good chronograph to determine the best combination of speed/shot count/accuracy. I really don't need more than 9 for anything. What others should know:This is in my opinion THE best value and most "bang for the buck" you can get from a mass produced pcp repeating air gun. The same features on other mass-produced and semi custom pcp air guns cost you at least TWICE as much! It's ONLY competitor is the M-Rod, but this kicks the M-Rod to the curb in usability and power adjustability with just as good accuracy. ONLY thing M-Rod has over this is a better trigger. By all means get a good big 4500 psi air tank for this. By far my favorite gun and uses a lot of gas even on low plinking power as I use it that much! Just BUY IT. You won't regret.
Things I would have changed:Revolver should not rotate once a pellet has been fed in, if not careful u can jam 2 pellets one after another and jam the barrell. Safety can be automatic, and the instruction manula should be more comprehensive, it is totally basic and U cannot make out anything from it, lots of confusion on what is high , medium and low settings, conflicting views on net also, I tried my self and realised that the small dots direction is lower and large dot is higher. The dust cap on the fill probe area is loose and about 100 shots later just pops off, can be improved What others should know:Buy a Air venturi G4 hand pump and fit the fill probe onto the hose directly , tighten with a wrench, not adaptor is required, works smoothly, have used only that for refilling, no hassles, yes refill once U are in the lower side of green zone, less efforts required to pump upto the red zone, only pump upto the 200 bar , check the pump's gauze not rifle's as rifle gauze is not too accurate..
