Shoot Test: Version 4.2.3 Spall Guard and Maingun Patriot Plate

Via WiscoDave

Spall guard and plate mounted in witness material.

As many of my readers know by now, steel plates offer tremendous advantages (low cost, extreme durability/multiple hits, thin profile), but do suffer from issues with front-face spall (fragmentation caused by defeated rounds) and weight. Most solutions that attempt to address this issue exacerbate the weight, and negate the advantage of a thin profile.

D-Rmor Gear spall guards address the issue while remaining lightweight and keeping the thin steel plate profile, while stopping 95-98% of all front face spall. The newest version exhibits improved extreme angle spall capture, as shown by the test below.

The plate used was the excellent Maingun Surplus Patriot plate, in flat profile. The plate was placed at a 12 degree angle (to focus the splash pattern more strongly toward the upper edge where the neck/throat would be). This is closer to a worst-case scenario shot, since the residual velocity of the spall is higher.

The test rounds were M855, 20″ barrel, 3000 fps @ 10 FEET. The witness method was a cardboard box. The shoot consisted of two shots, the first with the D-Rmor Gear Version 4.2.3 spall guard installed, the second with the bare plate. The pictures below show the witness box after the first and second shots for direct comparison purposes.
