Thanks for the kind words, thought the "retro nuts" would appreciate it, frens, sure looks good, that's an original Belgian Energa on an original Belgian rifle I assume LOL!, Dogpilot, nice combo there also, from what I understand the grenade that your M31 trainer is based on (not sure what the model was, not an expert of rifle grenades by any stretch!) was the one which saw the most use w/the M16 platform in US service, it came after the US version of one I have & pretty much replaced it by about 63-64, although not much use was made of rifle grenades overall w/the M16 platform in general. Hal, thanks, glad you enjoyed the pics on the site, I'm at about 4100 so far & just revised the account so there's no limit!, got tons more stuff to photograph & put up, actually just added a section in the M16 accessories album w/most of the ammo/mag pouches that were used w/the M16 series 1959-1990 or so, so I'll be adding ,ore pics, albums & info as time goes on, too bad you got rid of your AR180!, I really like mine, it's an original Costa Mesa rifle & just fits w/all the "retro" AR's, kinda of a cross between the AR's & my other "passion" Soviet, & AK's, the 180's kind of the ideal between both worlds hahaha!
