i have come across many good products for the mini over the years. if i had to choose 5 it would likely be:
1) WARNE QD rings:
this just makes sense imo. not only a great product, but very handy in removing the scope for cleaning while maintaining very close to zero. great at the range to when you want some time with scope AND irons.
2) choate hand guard:
although my true love will always be for the old school wood hand guards, the choate is definately a second best imo (and at a great cost). dump that ugly factory number ASAP imo.
does what a strut is supposed to do for a mini (accuracy improvement, heat sink) and i appreciate the thorough testing accu-strut did to prove their product.
4) specter gear 2 point sling:
love it! fits the looks of the mini and works well imo.
5) ANY flexible cleaning rod:
will save you a headache cleaning imo.
ruger factory mags (only ones worth having imo), wilson 1911 buffers, redfield revolution 2-7 scope (good glass, perfect fit), john masen recoil pad (for looks), wipeout bore cleaner, hornady v-max ammo (very accurate in my gun).
will report back if i missed somethin'!
