Want to Buy WTB Springfield Hellion Bayonet, Lunartech Upgrades, AR Mags, RA556B, Kung Fu AR Grip

Title pretty much says it all. I know it's more niche stuff, I'm really looking for the Waffentechnik bayonet before I buy it new. If you have any of the Lunartech upgrades, I'll gladly take them. I'm also looking for any Winchester Ranger RA556B or a Kung Fu grip. As for the AR mags, I prefer PMAGs and Hexmags, but anything STANAG is great. Shipping to VA so capacity isn't a concern. I have CashApp and PayPal, and as always I'm willing to trade/reduce/negotiate for anything I have listed for sale
