The aluminum case feels rock solid in hand, and the forward seal disc fit into the closure with zero fuss—my first build took under ten minutes. Works perfectly with the 1320 reload kits, and the threads are buttery smooth every time I disassemble for cleaning.

The forward closure threads seated perfectly on the first try, and the aluminum case feels solid enough to handle repeated flights without any worry about wear. I’ve run three reloads through it so far with zero issues, and the seal disc keeps everything snug and clean.

Finally got my hands on this hardware set and the aluminum case is machined beautifully — everything threads together smoothly with zero binding. The forward closure and seal disc went in without any fuss, so I'm confident this will hold up for many reloads to come.
