Avoiding barrel droop — our engineering
Barrel droop is prevented through precise geometry and a resistance-fit mortise-and-tenon. We hold the tenon diameter uniform along its length and make the tenon slightly larger than the receiver mortise so the barrel seats tightly and consistently. The shoulder between the .920" contour and the tenon is machined as a clean step (not a ramp) so the barrel sits flush against the receiver and is fully supported. When the fit is correct, v-block screws only need to be snug (~10 in-lb) — enough to prevent forward movement without distorting alignment.
Installation & break-in tips
• Prep: Remove paint/debris from the receiver mortise before installation. • Lubricate: Apply a light anti-seize compound to the tenon to ease installation. • Seat: Start the tenon into the mortise, then turn the rifle over and gently tap the rear of the receiver with a rubber mallet while aligning the extractor slot. • Break-in: Run two magazines through the barrel before evaluating groups; repeat when switching ammunition brands. • Cleaning: Keep the chamber clean but avoid excessive bore scrubbing — over-cleaning can reduce accuracy. Typical bore-cleaning interval: ~500 rounds (varies by ammo).
