the fully shouded barreled prowlers with the thicker, super-solid plastic stocks were totally fun for me...i guess they were the older versions. .177 was actually too hot, but those silver jet look-alike things from h&n really made a huge difference. 900 fps with 12 grainers - about a quarter groups at 60+ yards. it was cool (that one actually had plastic muzzle break - like the titans now). i did the radio control car bearing trick, but it was too sensitive. there's also a bushing for those same bearings that are 1mm less in height, not quite as good because it's not actually a roller bearing - but much better than the dang gun going off and scaring me before i'm ready....i hate that crap.....i have friends that love those 'c'-hair triggers, but not for me. ...the older version .22 prowler ; however, much more fun ! it was really consistent 725-730 fps with premiers and cloverleafed with same pellets at 25 yards. i kept it in the truck because i got for $60 and there just wasnt much that could mess it up bouncing around in there - and i try to have a loaner on hand when i am taking in an airgun for repairs. (i miss that thing, now that i think of it.) i even tried a np2 ram in it - both ways, inverted and straight up - but there was not enough gain in velocity too give up how smooth and quiet the loaner was. there's not much else to do on these prowler-types but to finagle the trigger and hone the tube (cross-hatching with slow break hone, long complete strokes in and out).....and i had to file down the trigger guard where the moldings came together. .........what sux is , those are chinese barrels. if you get a good one, it's great ! if you dont, exchange asap. problem is that you wont really know for sure until you season the barrel up by shooting about a half tin of walmart premiers thru it , and then (wish they still made the .22 premiers in the 625 box, which would best) using some ftt's or jsb's.....those .22 benjamin destroyers work well too....as long as each pellet fits in the breech the way, the same tightness - you'll find out best. ... the np2 guns have american barrels and cost twice as much from crosman parts dept. but they are great - i just had one lathed down to 7/16" od so that it would fit onto the pcp carbines i make, and the 2400kt co2 types.... you know what ? outta all the different crosman/benji gas ram rifles i have messed with - the .22 benjamin nps special edition was the best ! even the guys at crosman cust serv tell me good things about theirs .... i have had two of them go thru my hands....had the smaller prowler stock - the one where you can feel the cocking arm as you hold the forearm...had 3-9x40ao cp mildot scopes...american barrels....and shot a super consistent 760 fps with good premiers and accurate with the same...very easy to cock and shoot and quiet. they had els gas rams....obsolete part now....closest thing you can get is a ram for .22 benjamin rushmoore ....cbt trigger (i think that has an els part number, too).... check the nps out as compared to np2 :

....the benjamin rushmoore was made for one year (only for academy sports, and maybe big 5, or another retailer)....i snatched up 5-6 of these as they went on clearance here...it was my second favorite of the crosman corp gas ram rifles : https://www.youtube.com/watch?v=C1FXVyENusM
