Be careful if the barrel is less than 18 inches.
Per the ATF:While a receiver alone may be classified as a “firearm” under the Gun Control Act (GCA), SBRs and SBSs are classified in totality under the National Firearms Act (NFA). A firearm that meets the definition of a SBR consists of a rifle that has a barrel less than 16 inches in length. A SBS consists of a shotgun that has a barrel less than 18 inches in length. The serialized receiver is recorded for registration in the National Firearms Registration and Transfer Record (NFRTR).

Remember RUBY RIDGE!

Buy it and send it to Brileys for sleeved barrels. Bend the stock, fix the skeleton butt plate, refinish and rechecker and you have a very cool gun. Nice winter project.

I kinda like it. Too bad about the barrels but I bet Brad could make a set of nice 30" or 32" Damascus barrels using the original lug block. It would be costly but might make a nice finished product.
I can't say for sure that the grip cap isn't inletted... I'd need to have it in hand.
I'll bet that gun has some interesting provenance.

Darryl, I have emailed them three times about the barrel lenght and have not gotten a response. I'll call them tomorrow. I have a few other questions anyway.

In my opinion, the price might be a bit high considering the barrels and wood. Mostly the barrels.

I found this same gun from a June RIA auction. It was in a lot with three other guns, another early lifter w/30in. barrels, a Trojan 12 that was listed as a VH, and a Hopkins & Allen hammer 12. The whole lot was estimated at $950-$1400.
Don't know the final price on the lot.
The RIA description of the D doesn't give me much confidence.

I talked to Mike today and he was very helpful and gave an honest descrption of the condition. He says there's a pretty deep dent in the left barrel and the right barrel is fairly pitted.
