@bighit look mate i am not sure why you stalk me on the threads and why the dislike but i am putting you back on ignore and i would think you would do the same for me you dislike me that is your choice but stalking a person on a site mate you need to get out .

Sorry but can you not move on i am not interested in having petty side swipes all the time thank you .

To the OP as another person said he got it done for £10 why take the chance and yes you may be able to buy a new part but why incur a larger cost just to try it on one gun , i understand if it was going to be a big thing do loads of guns and or a business but to save a couple of quid well just my point as i say like the blueing you can do a okish job with the cold blueing but if you want a proper job leave it to a pro
