About
What it is, and why it matters
The Brocock Compatto XR is a compact, lightweight pre-charged pneumatic (PCP) air rifle produced by the British manufacturer Brocock (BRK). It uses a smooth side-lever cocking action feeding from a removable self-indexing 10-shot rotary magazine (a single-shot tray is also supplied), drawing air from a slim 150cc buddy-bottle tube through a self-regulating valve. Built on an ambidextrous synthetic stock with a match-grade barrel, full-length integrated silencer and a three-position power selector, it is offered in .177, .22 and .25 calibres for hunting, pest control and target shooting.
Brocock began in Birmingham's gun quarter in 1989, originally famous for its Tandem Air Cartridge (TAC) self-contained air cartridges. After acquisition by the Diana Group in 2013 it was co-located with sister brand Daystate, and later adopted the BRK name to mark its move into premium regulated PCP rifles. The Compatto XR modernised Brocock's long-running compact Compatto line into the XR platform.
The Compatto XR is the compact, tube-fed member of Brocock's XR range, sharing its action with the larger bottle-fed Commander XR. UK-spec rifles are limited to around 12 ft-lbs (sub-legal-limit) with high shot counts (around 90 shots per fill in .22), while FAC/export versions run up to about 30 ft-lbs. The 150cc integrated air tube keeps the rifle short and light at 864mm and roughly 3.17kg unscoped.

Trajectory
What the round does downrange
Solved from the muzzle figures and the bullet. The dashed rule is the effective range on the record, and the crosses are the steps the solver returned.
No load solved for this record yetThe flight path is computed from a cartridge and a bullet. This record has no ammunition filed against its chambering, so there is nothing to solve.
