Can’t Find .50 Beowulf?
Are your magazines pinned too tight? Not sure if your .50 Beowulf magazines will load to 5 rounds and lock in on a closed bolt? Can’t find enough .50 Beowulf ammo to do a proper test?
Ensure your magazines are giving you 100% of legal capacity with these 3D printed .50 cal dummy rounds. The difference between pinning to 5 and 5.5 rounds is over 5.56mm of usable space that could prevent your magazines from locking in on a closed bolt.
Made to the precise case diameter of the .50 Beowulf cartridge (+/- 0.01") and a comparable overall length, these dummy rounds allow you to check that your magazines are properly pinned.
Dummy rounds are available in packs of six for $15, otherwise $3 each. Available colours are blue, grey, gold, and translucent. Pricing for two-toned (choose any colour combination) dummy rounds is $20 for six, otherwise $4 each. Buyer pays shipping.
*Note these are not snap caps, and they are not made exactly to official .50 Beowulf specs. The diameter is the same, but these will not lock in a .50 Beowulf chamber. The case rim is modified so as not to infringe on any intellectual property. .50 Beowulf is a proprietary cartridge of Alexander Arms. Do not attempt to chamber in any firearm.
