We built this Bulgarian parts kit on a Childers receiver. Did a front end conversion using Jmac gas block and muzzle device. SLR Rifleworks forend and gas tube. Magpul stock, US Palm grip. The receiver forend and gas tube are Cerakoted in Battleship Grey, the rest is coated it Graphite Black Cerakote. 
We did some Cerakote work to this WASR-10UF. Some Gold, Graphite Black and some Dragons. 
We milled in an Aimpoint Acro by modifying a Glock MOS plate and then milling that into the slide. 
This Glock 34 gen5 got some nice windows machined in the slide. Then we Cerakoted the slide in Gloss Black. To highlight the windows and match the magazine extension we Cerakoted the barrel in Firehouse Red. 
This Sig P320 was a factory optic ready pistol. The customer wanted the option thr have a rear sight. So we milled the Holosun 507C in deeper in the factory location. Dawson Precision Glock suppressor rear was milled in behind the optic. Front sight is a Dawson Sig night sight at the proper height to match the rear. We also cut a window in the top front of the slide and then Cerakoted the slide in Sniper Gray. 
CZ P-10 F we milled in a Holosun HS507CV2. Factory rear sight location was milled out. Dawson Precision Glock suppressor sight was milled in behind the optic. Front sight is a Dawson Precision as well at the proper height to work with the Glock rear. 
This HK USP in .40 cal got an RMR milled into the slide. The slide and frame were also Cerakoted in F.D.E. 
We did a little @gun.candy on a couple of pistols. The Daniel Defense is done in Mako. The STI is done in Carbonite. Both look way better in person. 
We built this PSL recently for @bloc_parts. They make the SVD forend conversion parts as well as other great parts. It was a virgin kit. The receiver is M&M Inc. The pics that look professional are @collateralexposure
