NDZ Invert bolt. Improves shot consistency, reduces bolt wear and reduces cycling mass. Offered currently in 2 versions. Our aluminum hardcoat/ teflon treated bolt and also our lightweight delrin version. Whichever the choice, both offer less friction and less weight.
tapered face allows sooner ball drop into breech
delrin version, weighs 5.7gr. thats 6.3gr.less than stock, thats 110% less weight than stock w/o-rings installed
aluminum version is 8% lighter than the stock 12gr. bolt
either way, both offer reduced friction
improved shot consistency
Note: Dirt and other foriegn media can extremely shorten the life of your delrin or aluminum bolt and or your marker breech.
The New Designz Invert Mini Tru-Flo Bolt is newer, so it should be commonly available, both new and used.
New designz bolt and spring

So far none
New designz bolt and spring kit have made my marker faster quieter it uses less air. i feel that it turn my marker into a $1000 dollar marker feel better. right out of the box this marker rocks, with this bolt and spring kit its going to help you play better, get more paint per tank less kick.
for you guys thinking of buying this bolt and spring kit, NDZ email me a starting point on setting for adjusting dwell and psi by the way my board is stock and im using the blue spring (lightest)
here is a good starting point dwell 5, 150 psi, back cap 2 turns out or dwell 15, 130psi, back cap out 2 turns adjust as needed settings may vary.
The adjustments Im using are dwell 18, 150psi 2 1/2 turn and im shooting at 280-284fps before when my gun was stock but broken in, my setting were dwell 28, 200psi and back cap about 1/12 to 2 turns, big improvement. hope i have been some what of a help.
note: my broad is 1.2v and my dwell range from 1 to 70 blinks. owner manual is 1-45 blinks why I dont know. if your broad is 1-45blinks you might have to set your dwell lower.
Great upgrade for the mini, thanks for taking the time to read my review.
