About
What it is, and why it matters
The Air Arms S510 TDR (Take Down Rifle) is a British pre-charged pneumatic (PCP) take-down air rifle introduced by Air Arms in 2017. It splits into three sections that store in a foam-lined hard case and reassemble in seconds with a repeatable lock-up, using the S510's smooth side-lever action to feed a 10-shot rotary magazine. Fitted with a fully shrouded Lothar Walther barrel and an integrated Q-tec moderator, the TDR is aimed at hunters and travelling shooters who need a compact, packable rifle without sacrificing the accuracy of the standard S510.
Air Arms is a Sussex-based airgun maker founded in 1983. The S510 TDR extended the acclaimed S510 platform into a genuinely portable take-down format, drawing praise in UK airgun group tests for combining travel-friendly packability with the accuracy shooters expect from a full-size Air Arms PCP.
Offered in sub-12 ft-lb UK-legal form and higher-power FAC versions (up to roughly 20-29 ft-lb in .22). A regulated variant, the S510 TDR R, adds a fitted air regulator for improved shot-to-shot consistency.

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.
