For me, the addition of the side lever transformed the .25 bullpup into the market leader for shortest, lightest, full power .25. that's incredibly accurate and reliable.
My wishlist for Vulcan would be:
add a 20 MOA rail
quiet down the hammer with no bounce or free floater
a black soft touch synthetic that's actually lighter than the wood and not slippery slick plastic that weighs a pound more
polish/refine the trigger and linkage
some finger grooves for the pistol grip
a lighter more attractive skeleton stock for the Tactic
an 80 FPE .30 cal that gets 40 shots per 250 bar fill that's less than 34 inches OAL and under 7 lbs
The one fitted to the gun on the stair is one of those. Nice and chocolately brown but NO grain. Fine by me tho - it's 1 lb lighter than synthetic.
some "selects" I purchased the bottom dark one. See gun above on stairway. The middle one in this pic had the nicest grain of the three but has that orange color that doesn't appeal to me.
