Hello, im trying to find a 700mm .30 barrel for my fx dreamline power pup. Would a 700mm .30 crown barrel work if i use the shroud of my 700mm .25 barrel that i already own?
Short answer is no lol .


As stated in the other thread I answered in a pic goes along way .
Red = The shrouds/barrel housings are different diameters on the dreamline , crown , impact . As mentioned in the other thread there are several different iterations of these through out the years so it complicates things a lil haha . you can see the size varience in the red circled above in the current crown , dreamline , impact systems . You mentioned you were having a hard time finding the .30 caliber 700 mm . you could if you had to with very little modification use a impact barrel on your power pup and get bye the diameter of the barrel housing will be smaller than the dreamline shroud on the ul barrels but it would work if you get desperate .
orange = These small plastic disc are different sizes in the dreamlite and crown shrouds . you can see how different in the third picture they are also caliber specific . In the earliest versions on the dreamline before the skinny shrouds came out they were the same but as always fx canged that haha. It is hard to keep up with at times due to all the changes .
yellow = the liner retention pieces are all caliber specific . you would as madeintheuk mentioned above need to obtain these plus make sure the exit piece marked in green did not clip on a .30 caliber pellet . I say this because again it has changed multiple times throughout haha. you need the specific disk as well for the .30 caliber liner . the ul system and the older one is pictured above as well the impact barrels still use the older version to an extent.
green = This is not without several versions as well . the lower green one circled chan be changed according to caliber and is an example of a newer one. the ones in green circled in the upper right of the pics are fixed caliber and require the correct one. Also in some of the older ones they were universal in a .30 cal diameter haha.
I am not very good at typing online and am sub par in communicating so I apologize for that . I hop[e this helps you a little and hey either way I tried haha. You have a great evening Sir.


I also found it difficult for my finite self to communicate with you in three different threads for the same question haha.
