First off... how about a look at this cool rifle, the concept conceived by Airguns of Arizona and built by Brocock. Mine shown with Aztec Emerald 5.5-25x50 FFP Illuminated Reticle scope.
The magnificently shrouded barrel makes this rifle incredibly quiet - so quiet that you may not even choose to add a moderator to it, though it is ready to accept a standard 1/2" mount moderator.
Those of you who have this rifle, if you would, please contribute to this thread.
I have a few questions to start things off. EDITED, subsequently, to provide some answers.
1) I believe there are six power levels selectable - does anyone know the approximate power levels (by percent?) at any of the five settings below "full"? My understanding is that from the factory, the full power level on the .22 model gives 32 fpe? Any idea what the other settings give, power-wise?
2) When the lower power levels are dialed into the power control, is there any conservation of air used? Or does the power level simple reduce the amount of air going down the barrel behind the pellet? (I've heard some say that there is no savings in air usage and others say that there is air conservation - a higher shot count when using reduced power.) ROBERT of AoA tells me that the lower power settings reduce velocity but do not significantly conserve air. The Huma reg, however, makes the shot count on this amazing. On full power, I'm getting over 160 shots on a fill (from 240 bar down to 150 bar)!
3) Adjusting/Reducing air pressure to the regulator: I've heard that reducing air pressure to the regulator directly, while there is air remaining in the bottle, will damage the regulator and the rifle. Is this true? And, is there a safe way to reduce air to the regulator while air remains in the bottle? THE Huma regulator control screw can be turned clockwise to decrease power when firing the rifle (without pellet). The moment the rifle is fired, pressure on that screw eases for a split-second, and at that time it can be turned momentarily. Be ready, with the screw driver in place with slight clock-wise pressure, at the moment you discharge the rifle (without pellet). Repeat as desired. To INCREASE power, the screw can be turned Anti-Clockwise at any time.
4) Picatinny rail - is it pretty much necessary to mount a scope to the picatinny rail? Or can one just attach scope rings directly to the 11mm dovetail on top of the receiver? SOME people mount directly to the 11mm rail (not using the picatinny rails) and use high mounts. Others use the picatiny rail with low mounts.
5) Chrony results: if anyone can provide crony results with the gun at factory settings, please do so. If possible, including some or all of the different power levels? MINE was choreographed at AoA with 15.89 pellets giving an average of 911 fps.
6) I've read that the hammer spring adjustment should be locktite secured after making a desired setting - is there any locktite on the hammer setting when the gun is in factory condition? THERE seemed to be a bit of locktite on my adjustment screw, but it was easily broken with pressure turning the screw.
Any insights that might be shared in this thread would be much appreciated. (I'm picking up the Bantam Sniper .22 HR that I purchased at AoA tomorrow! Can't wait to shoot it.)
