Configuration - As delivered with addition of carbon fiber barrel sleeve, DonnyFL Sumo, and Optisan CP 3-12x32p scope. Cleaned barrel and started shooting.
Good balance, accurate with JSB 18.13 gr Jumbo Heavy pellets at hammer settings of 1, 2, and 3. Hammer at 2 was most accurate. Looks like factory setup is for JSB 18.13 gr pellets
Initial magazine insertion was tight and felt like pellet probe was dragging when cocking. This was so concerning that I bought a second magazine to see if it was a magazine problem. The new mag exhibited the same issue. Both mags smoothed out after about 100 pellets through each mag.
The regulator gauge is small and hard to read accurately. Fat needle with a compressed scale. It is a wika/fx branded gauge so I believe it is accurate but very hard to read (at least for my old eyes). Ordered a 23mm Huma gauge with slightly larger scale and thinner needle to see if it would help me accurately read the gauge. No issues with bottle pressure gauge.
Overall an excellent handling and accurate bullpup right out of the box!
Next step is to experiment with slugs. Then see if there is a setup that will allow me to shoot slugs at a high hammer wheel setting and a good pellet setting at a lower hammer wheel setting without having to change regulator settings. Maybe wishful thinking but worth a try.
