BAM the Koejak .25
Hiya,
some time ago a friend from Belgium asked me if i wanted an defect BAM B50, the BAM consisted of a bag of parts and offcourse i wanted the mortal remains of the BAM. He sent it to me. I discovered the BAM on the Dutch Airgunboard. A well known HFT shooter bought it and fitted the Daystate stock. I had it in the gun vault for some time. Like i said,the BAM action had a Daystate stock. Great. I like that. http://i.imgur.com/8K3lS7Z.jpg Last summer i made a new valve for the gun and i decided to put the Hatsan .25 barrel i had lying around in it. I bought the Hatsan barrel for some 50 dollar.THe Hatsan barrel is quite a bit longer than the BAM barrel. I heated the breech with the barrel and it came out pretty easy. http://i.imgur.com/S1OSnVF.jpg The Hatsan transfer port didn`t match but since i`ve got a lathe that`s no problem. http://i.imgur.com/eDXbnxz.jpg The diameter of the Hatsan barrel was 11 mm, the BAM breech asks for 12,6 mm. I reduced the diameter of the Hatsan barrel to some 10 mm and made a bushing to get to that 12,6 mm. I had a piece of Cometa barrel in my drawer and i made the bushing af that piece of barrel. No better material to make a barrel bushing of than a barrel doncha agree? http://i.imgur.com/ThE91Hh.jpg The cheap ass Chink lathe working like a madman. http://i.imgur.com/R81GEuF.jpg See if it fits. http://i.imgur.com/Aa7xox5.jpg To be continued...... |
the Koejak
Oi,
since the BAM was a .22 the probe is a .22 too. Luckily i found a probe that i seemed to have for some with a bigger diameter on the front end. I`ve got lotsa o rings and because the diameter of the probe is larger there`s no problem to air tighten the barrel. I used a reamer to modify the breech a bit so the pellets would chamber without too much hassle. In the end it worked fine. http://i.imgur.com/rN2HeaX.jpg http://i.imgur.com/RFtnx5O.jpg Next thing is to drill and thread the breech so the barrel can be placed. http://i.imgur.com/90UfzUZ.jpg I don`t like barrel bands but because of the length of the barrel i thought i had to use one. So i took something off of the outer diameter of the barrel to make the barrel band fit. http://i.imgur.com/EZLirc3.jpg Eventually the barrel band fitted. http://i.imgur.com/ezjG0xo.jpg I put the gun together, bought a cheap ass scope (60 euro`s) and took it to the range. Me and four other guys made our own shooting club, we`ve got a 100 meter indoor track. It`s dirty, it is moist and cold and dark and sinister but we don`t give a hoot. It`s our dirty, moist, cold and dark and sinister shooting range. We`re pleased with it. For two or three weeks i shot the Koejak on the 50 meter track, it didn`t do too bad, groups were some 2". Not too bad for a $110 gun innit? At the 100 meter track it wasn`t all that good. I didn`t mind, this gun was made for the 50 meters. Untill i took the barrel band off and hopped over to the 100 meter track. http://i.imgur.com/oGeoB0U.jpg http://i.imgur.com/KJDrWS9.jpg http://i230.photobucket.com/albums/e...pshtwv1geg.jpg Time after time the Koejak scores great. http://i230.photobucket.com/albums/e...psah0plwlt.jpg Shoots like a $1500 gun. This one costed 110 bucks. 111 bcks since there`s a dead moon sticker on the stock. What`s a Koejak? I hear ya mutter. It`s 'kloatsek' Frysian for nutsack -like asshole- by my three year old grandson. Take care. Roel |
Holy cow. Great write up my friend. That is one heck of a shooter you have there for so little money !!

Roel that's a great write up and pictures you've shared. Even better that you turned such a pile of parts and small sum of money into a fantastic shooter. Can't wait to see more of your collection and adventures in your "dirty, moist, cold and dark and sinister shooting range. "

Very nice results. I gotta say, I'm really impressed with the accuracy outta that thing. Good work.

Dirty, moist, sinister, cold and dark. Like i said.
