About a year ago I purchased a 1950s Australian SLR built on a DSA lower receiver from Duffy's. It was priced at $3500, which was very steep even though they are hard to find in MD. I knew about the whole inch vs metric debacle with MD banning, and they informed me these were perfectly legal to own. I took a good portion of my collection there, expecting to walk out with the gun and maybe even some cash too. They completely shafted me on the guns giving me pennies on the dollar for them, but I settled and ended up paying $900 for the SLR. Lo and behold, I take the gun out multiple times and the rifle refuses to cycle and eject rounds upon firing, rendering it a straight pull rifle. I tried all the gas settings, cleaned it completely, and lubed it up. Next time still the same thing. I was planning on taking it to a gunsmith because my RSO mentioned it might be something with the gas rings on the bolt being worn out. The other day i decided i just wanted to get rid of it so I took it to Continental arms, and they wanted nothing to do with it. I then took it to Gunbunker south, and they seemed interested until they went onto the Maryland registry and found out that the rifle is illegal to own in MD due to parts being interchangeable with Belgian FALs. I then hurriedly took it to Pennsylvania to sell it off to get rid of it. Duffy's has done this before when they were selling CETME Ls a year or two ago. They will sell you grey area firearms that aren't specifically approved or banned on the MD registry. Now if you buy one of these and they end up illegal you are breaking the law. These guys are shafters and skirters of the law and only care about making a quick buck. STEER CLEAR OF THEM.
