I've broken a few push-pins on my A-5 before, and although I could not justify the cost, I broke down and figured I'd be down with my push-pin-purchasing by buying these stainless steel push-pins. I bought them off eBay from a dealer that has a store which goes by the name of Alamo City Paintball (o

   

If you have stock wobble, you can always remove that problem with a tiny bit of black electrical tape. on the inside of the reciever or the area of the stock where it inserts into the reciever. I've gotten stock wobble with stock A5 pins, HK pins, and the Alamo pins pretty much across the board with 3 different A5's now; I'm thinking it's just slight variations in design tolerances in the A5 line. Nonetheless, the HK pins simply do not break like the stock pins do, so regardless of a slight wobble (easily fixed) they're still orth it. Heck, anything is worth it over the stock pins!

it's not a "slight" wobble it's a my stock is useless wobble with the HK pins. I ended buying regular allen head bolts from home depot for $1.70 each and some nylon locking nuts and haven't had ANY wobble or problems for that matter ever since!!!!!!

HK pins are a waste of money!!!!

I would say then that either your stock or reciever halves is/are possibly out of spec - it happens. I personally own three A5's, and they all have HK pins & stocks on them with zero problems. Some of my friends are also running the HK pins and they report no problems either. I only know of one guy personally who actually had problems with them, and that was on an A5 with polished internals. We figured that he probably removed too much material on the inside and now he can't get any kind of stock to run on his rig at all. I'm just suggesting that before you knock the pins (they are after all firearms grade quality) examine your rig first to determine if that isn't the actual problem.
