Frequently Asked Questions

What caused the Vepr 5.45x39 meltdown test to fail prematurely in the previous attempt?

The previous attempt failed prematurely because the primer sealant from commercial ammunition gunked up the firing pin. This test uses genuine 7N6 military surplus ammunition to ensure a proper service performance test.

How many rounds did the Vepr 5.45x39 rifle fire before its barrel failed in the meltdown test?

Across two separate torture tests, the Vepr 5.45x39 rifle fired a total of 1,491 rounds before its hammer-forged, chrome-lined RPK-style heavy barrel ultimately ruptured.

What type of ammunition was used for the Vepr 5.45x39 meltdown test?

For this revisited test, genuine 7N6 military surplus ammunition was used. This ensures a proper 'service' performance test, avoiding issues like primer sealant gumming up the firing pin seen in previous attempts.

What was the nature of the catastrophic failure during the Vepr 5.45x39 meltdown test?

During the continuous full-auto fire, the barrel began to droop significantly. Eventually, a catastrophic failure occurred where the barrel ruptured near the gas block, with the projectile exiting the side of the barrel.
