HYENA AR-15 SBR Bolt Carrier Assembly Update

After looking again at some videos on the inner workings of an AR-15 I decided to make some slight tweaks to the HYENA AR-15 SBR bolt carrier assembly. I also created a new charging handle which I think is more refined and definitely more accurate...

I think the next time I make an AR-15 I will start from the bolt carrier assembly outwards as it seems this is where the gun derives its distinctive look.
