>>10471636Knock-off technic axles and pins and the parts they connect with can be pretty tight, leading to difficult assembly and disassembly. Although still theoretically possible, one can run the risk of damaging the parts when dealing with a particularly stubborn connection. Can guarantee that at least part of this Sluban M1A2's barrel is set for life, heh.
That said, all my experiences have been system-type sets with some technic parts within the build, haven't tried a pure technic one so maybe there's a higher degree of quality put into them I'm unaware of.
