TN also performed conversions that used the G36 magwell, so what I have is a G36 magwell conversion done by TN, not the TN (or is it really SW?) AR mag conversion.Last I knew the TN conversion used AR mags. If you want to use G36 mags you'll need to go a different route.
From what I can see, here's what you 've got there...http://gunbroker.com/Auction/ViewItem.asp?Item=86893176
Thats the one on gunbroker, i was wrong on price but still does not seem bad.
If KY allows you to have SBR's, then from what I understand (again, verify with your state and ATF), yes. However I'm not sure about the "call it an SBR" if it's really not one. If you're NOT going to actually make it an SBR, you'd probably have less hassle (and around the same cost) just getting the U.S. parts (assuming it doesn't have them already). The whole real idea behind registering as an SBR is so you can have as close to a genuine G36K or G36C conversion - using all genuine HK parts.So let me try this senario. I live in KY so I could get a weapon with any number or imported or US made parts and call it an SBR, then register it on a class 3 form under a corporation or LLC (to avoid finger prints and LE letter) ? Does that seem to work?
The ATF Tax Stamp on the SBR would be $200. Compare that to the cost of compliance parts and you're coming out ahead by going the compliance route. The only redundant parts on my UMP that I had to buy for compliance was the trigger ($30) and the mag baseplates (3x$9). If you aren't going to actually replace the barrel, it's not worth the extra cost and hassle to go the SBR route IMO.If you're NOT going to actually make it an SBR, you'd probably have less hassle (and around the same cost) just getting the U.S. parts (assuming it doesn't have them already).
