Standard carbine. The impulse is pretty sharp though. I am considering trying heavier. Be advised, my 14.7" PSA 6.8SPC mid-length CHF CL lighter-weight 1/11 4-groove, etc. (all same as yours except yours is 16") did *mostly* ok with an H2 buffer. Short stroked *once* on the first round of a full mag (most resistance) of Remington ammo (lowest charged) once it got a little dirty. It also would not reliably bump fire with this combination (stock is not against shoulder in this test, so carbine is allowed to move and absorb energy/recoil instead of all of it being channeled to the functional parts). H buffer has been fine so far. You might be able to get away with an H2 since you have a tad more dwell time due to longer barrel length, but if everything else is equal my bet is you'll not want to go higher than an H buffer for a good functional reliability margin. Thanks for sharing your data points as well. |
