re

thats strange as the a/c barrel back i bought does not fit it wont screw all the way in and stops about 3mm short and does not screw flush in the breach

could there be something stuck inside the mini obstructing the barrel.

re

no nothing infact just remembered that the lucky barrel thread looks different to the stock one looks like the stock one has one more thread if you know what i mean

have you looked down the barrel when fitted to see if there is a gap or step or anything?? (between barrel and breach)
if there isnt can you live with the cosmetic look of it not quiet fitting?

re

i think its sorted i think it felt different inside because it was two different bore sizes i can live with the looks as long as it fire's ok

 

[trigg503]

sorted

just had a play with the different fronts and have sorted the problem i think also the anno might have been to think on the screw thread (if thats possible)
cheers all for the advice

it's the same with my shocker it screws in fine but stops bout 4mm from being flush with the gun. think it may be a design fault. still works fine tho.
