ZiPFactory Supp. Upgrade Kit.

no instruction poorly made does not work well its a joke to much money for what they give you they show a supp in pic but do not send you one

pro:--great for adding additional muzzle devices that do not require indexing/timingcon:--about 1/2 too short if you plan on doing anything that requires indexing/timing--don't bother trying to use included barrel wrench in standard sight kit. you will strip it. vicegrips and a towel will do when swapping barrels

After altering my original barrel to where it was unsafe to shoot, I decided to replace it with Zip's Maxim Upgrade. Easy to remove and install. Very solid feel with a snug fit. It has has a thread on the end with a nut. Remove the nut and a noise suppressor can be screwed on. I wish it could have been maybe an inch longer. Accuracy is as expected, very good with open sights, and awesome with a scope at longer distances. Highly recommended.

Barrel comes unfinished, ends up rusting. Comes with a restrike rod to clear whatever is threaded to the end-cheap way of doing it. Does the trick if you want a threaded barrel, but it's priced too high for what you get. Just trying to make my Zip worth shooting... still haven't gotten there yet.

What a waste of money. I was led to believe that this came with a suppressor. not just a barrel replacement! Save your money, gun doesn't shoot any better.

This kit works with well with my Zip 22 and YHM Wraith Suppressor. The threading seams decent and I have not experienced any more FTF or Jams than normal using .22LR ammo. As always the gun likes the CCI subsonic more than the cheaper stuff.

For a threaded barrel that drops in the pistol...it is great. I do wish that the new rod actual said "charge" instead of just being a "restrike" rod

Easy to install, will update after I take it to the range!
