Apparently, on the 1st generation FN PS90, you can move the "tail" of the trigger return spring just a tiny bit and this happens...

Fuzzhead and I test-fired the Diabolus rifle at a local range the other day. It did very well, with just a few hiccups that are to be expected with a prototype. Everyone who sees and handles this gun likes it, and I think it's going to be a bit hit once we start shipping 'em!

The M14 is a classic rifle, and it's a handful on full-auto!

Just got one of the French MAC 50 pistols from Old Western Scrounger. The recoil is pretty snappy, so I put it on high-speed video to see if I could see why.

If you've ever used a tap, you can appreciate what it takes to thread a hole the size of a bicycle spoke, especially in hardened alloy steel! Something pretty amazing is that this footage is from an iPhone! BTW, this isn't "dry tapping"; those holes have Moly Dee in 'em.

The Armalite AR-18 isn't just a stamped steel version of the M-16; it's a beautiful, over-the-top example of the genre. Nearly every part is stamped, including the trigger, hammer, autosear. Interesting that they were made in California, England and Japan...illegal in all 3 now!
