Changed out the bi pod with an air soft one, as well as the carrying handle to make it look more realistic. For the barrel I hollowed out half of a recon barrel then used a different pvc pipe configuration where the PVC can actually be unscrewed and changed. In the pictures you can see the two different barrels I made and they are easily interchangeable. Below is what the barrel interface looks like. This is also before final paint job and weathering.
