I mean, they are expensive to produce and material costs have gone through the roof in the past 5 years or so. We would need to sell 10 blasters just to break even with materials and labor cost. This has always been the more expensive blaster to produce. Even more than a lewis gun T-21. This requires an offset armature that is stacked and welded and there's a bunch of parts to put together.
If I had to guess on price these would probably come in around $750ea +shipping.
