If you want the front end, I've been thinking about changing it out for something a little shorter. Shoot me a PM if you're interested.
The gun is built almost from scratch from an AGM 416, but it was a surprisingly simple build. This is pretty much all that I bought for externals:
Madbull Noveske body
Madbull JP Rifles Front End Conversion
G&P Motor Grip
Clone Magpul AFG
Clone Magpul ACS Stock
Clone PRI Industries BUIS
The buffer tube, selector switch, and rear sling plate are all that is left from the 416.
Because I went ACM on everything but the body and front end, the build didn't cost as much as it could have. Also, because it is converted from another gun, I can't really give you an accurate total cost. However, all those parts came to around $400.
And, actually, there is no tan part on that gun that matches any other tan part
