I am looking to buy some 40mm flare rounds before the 4th of July, Any recommendations on where to buy?  Thx

Only place I've seen them for a long time is gunbroker. Last batch someone posted a full ammo can of 22 white flares, went for $3200 a couple of months ago, I tapped out at like $1500. You can get 37mm stuff way cheaper.

Wow, that’s crazy expensive

There was a batch of 22 IR flares same seller, those went for over 9K, which is unreal. Another option is the 20MM flares and an adapter. Those are way more expensive now than they used to be, but still no where near the cost of the real deal.

Interesting. I missed seeing those IR flares. Everyone I know says the ATF is actively looking for those and confiscating them. Supposedly they are not exempt from explosive regulations because they aren't really "signaling devices" and the ones that made it to the market were never supposed to.

That could be an expensive confiscation.

Most 37mm flares will work in a 40mm. My favorite are the old ww2-vietnam Era flares made for the m8 flare pistols. They for well in an m203.

That is pretty insane that the white star Para flares went for $3200 a can. I know a dealer that still has a bunch that I passed on for $60 or so each. Had the opportunity to buy two cans for $2k before that.
