My friend received his kit today, the FIRSH rail was put on expertly, and the lower went together in about an hour. Fit and finish is absolutely superb, and matches the Mega lower *very* nicely.
The only problem we had was that the plastic parts bag had spilled all over the inside of the bag. Maybe an outer ziplock would help? Either way, the kit went together without a hitch. The extra detent sure came in handy!
Thanks so much for keeping on offering such quality kits. I'll be back for my second JT rifle as soon as I can afford it, and I'll keep recommending you to my friends.
