It's a 16" match-barreled AR15 with a proprietary DPMS .22 LR upper, Titan Ordnance lower, adjustable Eliseo stock, Geissele trigger, Accuracy Speaks free-float tube, Medesha Firearms sight extension
tube, and on down the list of target parts standard on most any match rifle build.
Using long strands of fiber that are housed by a protective tube, which runs through the sight extension
, Axion's sights' design addresses one of a number of complaints with archery sights-pin support.
His invention consisted of a one-piece sight extension
that was locked into place by forcing it down and into the lower corner of the slide bracket.
Requirements include long sight extensions
, small peeps, tiny pins, possibly a scope and ideally a long stabilizer--some guys even weight their bows to make them more stable.
