The trigger on our RBI test sample measured 5 pounds, 11 ounces, and the RB2 produced a 6-pound, 8-ounce trigger pull fresh out of the box.
300 Blackout has a 10 1/2-inch barrel, and the twist in it is similarly 1:7, in recognition that there will be a whole lot of shooters expecting to put heavyweight subsonic loads through the RB2.
The RBI has a carbine-length direct-gas system, and the RB2 has a pistol-length direct-gas system.
Site RBI had the lowest value for BD and thus the highest total porosity, followed by site RB2.
At RB2 and RL2, there was no apparent change in BD throughout the year.
Plots at the RBI site were pooled and separated from plots at RB2, RLI, and RL2.
The two Rio Limon sites resemble each other and are found at the other end of the gradient (high BD, low OM, low concentrations of C, N, K, and P), whereas RB2 lies in the middle of this gradient.
The values of C, N, C: N, P, and OM for RB2 were slightly lower than for RBI, but arc consistent with those reported for freshwater herbaceous wetlands (Mitsch and Gosselink 2007; Bantilan-Smith et al.
In our work, Na was not recorded, but it is likely that this ion is present in RB2, due to the presence of K.
This explains the high values of P in RBI and RB2, as these sites have a higher OM content.
In the rainy season, the pH was significantly higher in RBI and RB2.
