Maybe I'm the only one, but I've always hated the screw in front pivot pin on my Colt.  AFAIK, only Colt makes lowers this way, and I think they still do.  I need to get it drilled for the captive pivot pin, but I haven't done it yet.  I once bought a drop in pivot pin (unknown manufacture), but it didn't work very well.  It was loose, and it protruded too far out from the receiver for my tastes.

Anyway, I was playing around today with a spare HK pushpin, and guess what?  PERFECT fit.  This will work with a standard handguard or trigger group pushpin of any HK 9x series rifle, the stock pin will NOT work because they will be too long.  It's not as good as a true captive pivot pin, but it's a lot more convienent than a screw in pin.

Now where do you get an HK pushpin?  Any decent HK dealer should have a bunch.  I figure around $7 for a pin.  

Sorry, not digital camera, so no pics for now.

I don't know if this info is useful to anyone other than myself, but I thought I'd throw it out there...

I'm looking at the same thing on the LE Government Carbine I picked up. Small pivot, with the screw in pivot pin but they didn't drill it for the spring and detent. The Sporter Target I got last summer, though it had the screw in pivot pin, WAS already drilled for the spring and detent as well as the weep hole. Simple matter of getting a push pin, detent and spring.

I'm going to have my gunsmith drill the hole for the spring and detent, but will probably pass on the weep hole.
