Polymer guard fiddly
Reviewed on April 25, 2026Verified with Build

function once installed is correct but the install was fiddly because the roll pin holes were a touch undersized on mine. had to chase them lightly with a pin punch to seat the pin. once in, no movement

B5 ATG-001 guard
Reviewed on March 19, 2026Verified with Build

B5 polymer guard, locked to the lower with a roll pin. integrated lower contour gives a flush look. lighter than aluminum which is the appeal for a polymer build

B5 trigger guard install fiddly
Reviewed on March 11, 2026Verified with Build

B5 Systems trigger guard is well machined but the install was a bit fiddly because the roll pin required a specific punch size to avoid marring the polymer body. Once installed it sits flush. Larger interior than mil-spec for gloves.

B5 trigger guard high price
Reviewed on March 5, 2026Verified with Build

B5 Systems trigger guard is well machined but expensive for what it is - basically a milspec replacement with their logo. Polymer is dense. Roll pin install was standard. Functions fine, the price is the issue.
