Quick Specs

FAQs

Why choose real brass over polymer snap caps? Polymer snap caps are lighter than live ammunition and their rims can chip or degrade under steel extractors, leaving debris in your chamber. These dummy rounds are genuine brass — 9.48 grams, the same weight as a loaded .223 round — with authentic rim geometry and feed friction. Your training replicates the real thing precisely because the casing is real.

Are these compatible with both .223 Remington and 5.56 NATO? Yes — .223 Remington and 5.56 NATO are dimensionally identical. These dummy rounds chamber and cycle correctly in both .223 Rem and 5.56 NATO firearms, including AR-15 platforms.

Can these be used for dry-fire and malfunction drills? Yes — these are genuine brass .223 / 5.56 dummy rounds suited for loading and unloading practice, tap-rack-bang malfunction drills, magazine reload drills, and ball-and-dummy flinch detection exercises on modern centerfire AR-15 and 5.56 platforms.

Are these the same as snap caps? The terms are often used interchangeably. Technically, snap caps are purpose-built training devices with a spring-loaded primer cup. These are dummy rounds — genuine once-fired brass with a Hornady 55gr FMJ-BT bullet seated and crimped, and a spent, dimpled primer intact. For loading drills, malfunction drills, and firearm familiarization, they perform the same function. Read the full comparison on our blog.

Will all casings have the same headstamp? No — headstamps vary since casings are sourced from mixed once-fired range brass. All are genuine factory brass headstamps.

Do you offer a larger quantity? Yes — also available in Qty 100 at a significantly lower per-unit cost. Select your quantity above, or contact us for bulk pricing beyond 100 pieces.

How can I confirm these are truly inert? We offer a free shake-verification upgrade — contact us the day you place your order and we’ll add a BB inside each round. A quick shake confirms no powder is present. No charge.
