seems like a fairly good deal... SIG516 Gen 2 Upper Complete Receiver Assembly, 14.5 in, Semi, Special Configuration
Short Stroke Piston! Which is the same as any other Piston Driven AR! Fancy Language to catch more "Operators" LOL
If it only had Xtreme in the title then supply would never keep up with demand. It seemed that in the 90's-2000's, if you add extreme with an X in the front, you could sell anything no matter how ridiculous.
That link got me a 404. Zumzing steenketh to high heaven. Good deal? 750 frns, and shown as not available. Doesn't carry the Sig marks, either. SIG 516 GEN 2 UPPER COMPLETE RECEIVER ASSEMBLY, 14.5 IN, SEMI, SPECIAL | Scorpius Tactical LLC "Sorry, the SIG 516 GEN 2 UPPER COMPLETE RECEIVER ASSEMBLY, 14.5 IN, SEMI, SPECIAL CONFIGURATION is not currently available." Not so good a deal for me, anyway.
