Title: Problems with new Bnm disco kit
Post by: Shane johnson on April 08, 2017, 02:14:54 AM
I installed my disco Bnm complete kit a couple weeks ago and I've shot it 3 times. The first time I had it jam up about 10 times and I adjusted the magazine and got that some what under control,I am wondering if these mrod magazines are perticular about lead types. the 2nd and 3rd time I tried sighting it in am done I'm getting 4-6" groups at 20 yards. I don't know what the problem is? I'm really hoping some one has some ideas. Aside from the issues I'm having I think it's an awesome kit and I really hope to get this working proper.thanks to you all for reading this and any help you can give me.

Sergio makes some excellent products for sure. Are the magazines hard to install and remove? If so you may have to loosen the barrel retaining screws and back the barrel out just a touch. After clearing the jam, did you look at the breech O-ring? It very possibly was snagged and damaged or pushed out. That would explain any further hard to load and the inaccuracy.
Check these two things and let us know.
