UK site notes

Important legacy UK CQB BFG. The device is discontinued and generally encountered second-hand or as residual retailer stock.

Research notes

Archived UK retailer listing explicitly marks the E1 X4-S discontinued. The X4 base supported .209, 8mm, 9mm and 12-gauge/Magflash-type loads; the optional multi-shot base was .209-only. Audit 2026-10-14: Original Surplus Store model page now returns 404 and the Defcon orange page returns 410. JD confirms a three-shot .209 accessory for UK E1/X4-family units, excluding US E1/E2, but this does not verify X4-S overall dimensions or mass. No Jaeger IMPACT or earlier multi-shot TRMR measurements copied to this model. Existing X4-S data and legacy status retained as historical, not freshly verified. Source: https://jdairsoft.net/trmr-209-multi-shot-base Audit scope: technical specifications and source suitability; existing prices and legal commentary were not re-verified. Unfilled numeric 0 means unknown, except impact delay 0 denotes immediate activation.
