The Nuprol Bocca rail systems come with two steel barrel nuts to fit AEG and GBB guns and also include all mounting hardware and shims as required. These are very easy to fit yourself in no time at all!

These generally require a level of technical skill to fit properly so we do advise you have it fitted by a competent technician.

Any questions on compatibility, installation or if you would like one of our in house techs to fit the parts for you, please email us on [email protected] or call us on 01293 525880
