My back of the napkin calculations resulted in ~$4250 before tax and shipping, that includes hera stock adapter, acr stock, spuhr magwell and an aftermrket lower height full picattinny top rail.. add extra cost for barrel threading and a muzzle brake of choice if desired. That lands it firmly in the B&T territory and also requires sourcing parts from different vendors and putting it all together. Still a bit cheaper then TI imported G36, but not that significantly. I may just wait for another G36 shipment from TI next year, they bring them in small batches from time to time.
