Shipped and arrived extremely quickly. So quickly, my lower isn’t finished printing. Seriously.
The carbine-length buffer tube (7.25in) and spring (10.5in) were wrapped separately in heavy packing paper, and all the smaller pieces were organized and packed with care into heat-sealed bags (I immediately thought to myself, “now THIS is grown-up LEG0”). Quality is excellent across the board, and I will almost certainly be coming back for more very soon.
FYI to the next builder: there WAS a TPU hose-clamp cover included (sealed) in my kit, though not featured in the product images! I bought an extra not being sure, and I honestly might recommend doing that anyways… in case it gets ripped off and lost whilst running around barefoot on the range, Hoffman-style. XD
Thanks guys, and keep up the great work!!
