elrasho Posted January 29, 2015 Posted January 29, 2015 When firing my MP9 over a period of time, one of the body pins begins to pop out. One time it came right out! Any ideas why this is happening? I'm using Predator abbey 144a gas and it shoots at around 320 FPS. The body pin in question is the one furtherest back and it goes through the trigger arm in the gun.
Guest PT247 Posted January 29, 2015 Posted January 29, 2015 sounds like it is worn. You may be able to replace it. It might be that the receiver is worn though which will be harder to sort. Does the pin have any form of retention; a groove or anything?
elrasho Posted January 29, 2015 Author Posted January 29, 2015 Looking at the blow up diagram I'm missing part 111 which is a c clip. Any ideas what size this is so I can get another one?
Chock Posted January 29, 2015 Posted January 29, 2015 You could always just get a multipack of circlips, they are not expensive, most hardware stores will have them, or if there is no hardware store near to you, try these: http://www.ebay.co.uk/itm/NEW-SILVERLINE-INTERNAL-AND-EXTERNAL-CIRCLIP-PACK-255-Piece-245020/150689518282?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20140122125356%26meid%3D8e3d17a8d8ec4d28b682943b6ad876fc%26pid%3D100005%26rk%3D4%26rkt%3D6%26sd%3D270659863117&rt=nc or http://www.ebay.co.uk/itm/EXTERNAL-C-E-CLIPS-CLIP-CIRCLIP-DIN6799-FULL-RANGE-new/270659863117?_trksid=p2054897.c100204.m3164&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20140407115239%26meid%3D53be376712214712a97e0519fb1072bd%26pid%3D100204%26rk%3D6%26rkt%3D28%26mehot%3Dpp%26sd%3D311171258293 It's no bad thing to have some kicking about for future repairs, and a fiver is hardly gonna break the bank
elrasho Posted January 29, 2015 Author Posted January 29, 2015 Yep got some from Maplin and fitted in, the pin holds
