I acquired a AA HFT 500 <12 from a forum member a week back and set about creating my personalized version of this airgun.
I currently own 3 of these AA platforms which are all very similar. I also have owned the AAS510XR but it was a left side, magazine loading only model so i sold it for things that are right hand feeds. Why? because in Field Target those big parallax wheels interfere with left side loading.
First order of business was slipping the gun into an Aeron FT Chassis that came with a AA S500 XS carbine model I bought from another forum mbr... I'm using the OEM laminate HFT stock the HFT 500 normally comes with on my AA S 500 XS long version.
I have another AA S500 XS in carbine length which now lives in a GRS field target stock.
Then i changed the AA quirky fill fitting to a Foster QD .... easy peasy.
Added the Rowan slip on moderator adapter but i should have ordered a black adapter but ohhhh well.
Screwed on a Weihrauch moderator... phffft.
Mounted an Element Titan 3-18x50 FFP MOA IR scope on it with 34mm Sportsmatch inf adjust rings.
Added the Rowan 8 shot rotary "right side loading" mag - simplifies old finger fumbling in .177 during HFT matches.
Hopefully this weekend i'll get things zeroed up and post some current pictures.
Last pic is not the current HFT500 but my AA S500 XS - which is to give you an idea of the finished product.... the HFT 500 is much shorter.
Of interest: found it odd that the HFT 500 is a 2700 psi fill and all the other AA S series are 3000 psi fills? guess it has to do with regulated verse not regulated.
