  1. I've spoken to an ADF chap I know who's used the F90 GBBR, first time i heard about it was about 8 months before it was announced to the world as he's been using them for the past few years.

     

    I didn't believe him to begin with...

    He says its great fun and wishes airsoft was legal there.

     

    Genuinely cannot wait to get one, it will Tee off my AUSTEYR and ADF collection nicely.

    @MandalShArKit could be you have your npas turned too far down so all the gas is working the bolt and not coming out of the nozzle. 

    it worked, 
    Id just installed the NPAS a couple of weeks ago and left it as it, Id not tested it etc so didnt know the ins and outs.. The more you know!

  3. So I've built an M4 and an XM from parts now, and bought some bits from KY Airsoft..

     

    The issue is nothing shoots.

     

    I've put in a maple leaf yellow and omega nub, nothing.. back to standard hop parts..

     

    Nothing,

     

    Rounds do get picked up and either stay in the hop unit or roll out, I've adjusted the hops, no change. 

     

    Any ideas? 

     

     

     

     

     

  4. I think I've read more MPA failures than anything else.

     

    Interesting point on the o ring replacement though 

     

    I was looking into getting one.

    For fps, I’d probably recommend the angry gun mpa complete nozzle BUT replace the rear oring with the stock WE nozzle oring ( the AG one is a bit baggy and can stick in the bolt carrier)
    also do the bolt stop/ release mod for reliable bolt locking. Everything else is gravy.

    I also use the yellow maple leaf autobot rubbers with the stock hop chamber too. 

    What's the bolt stop mod? 

  5. I've been playing 24 years, owned a WE M16a1 a few years back for reenactment use, didn't actually use it in anger before I sold it.

     

    About time I got into GBBR'S really 🤣

     

    I've learnt so far..

     

    Don't bother with RA Tech kit unless is replacing the FCG.

     

    Keep it stock and install a FPS reducer ring over NPAS 

     

    Keep everything stock and replace as needed apart from a hop rubber.

     

    Use .30 rounds.

    Use propane or green gas. (Red gas when it's gets really chilly)

     

    Hows that for a start?

     

    I just want them to run reliably, I dont need them to do anything fancy.
