Delrin replacement for the stock Aluminum Cylinder inside your Matrix. Advantages: Better tolerances Super slick inside, cycles faster Works at a lower pressure than the stock one, helping to reduce ball breakage Includes 2 o-rings to fine tune to your matrix
The KAPP Kapp Bio Sleeve is older, so while it may be available used and in a few cases new, it is not commonly available anymore.
its amazing quality for delrin and smooth internal wall
may possibly swell because its delrin?
I was pleasantly surprised by the quality of this relatively inexpensive upgrade for the matrix. however upon more inspection i was amased by this low priced sleves quality, the internal polishing on the delrin is amazing , i have not felt a delrin bolt or part otherwisr that has been made that smoothly. i am truly impressed with the quality and build of the item, i would assume that because of the reduced friction i could get approx 50-75 more shots off my 45-45 tank .
overall a nice upgrade, best delrin quality i have seen, i might worry about swelling when exposed to some matrix lubes, although i have not experiencced this so thats why i give it a 9/10

Its super slick and weighs half as much as the stock piece.
You need a different size o-ring on the bolt sail.
i picked mine up on ebay for 11 dollars so i couldnt go wrong with that. when i first got it the first thing i noticed was the weight, about half the weight of the stock piece. it was much slicker and lets you run the lpr about a full turn down. I have only played with it in my gun once at the field and noticed my velocity was a very close spread i dont know why it made a difference with it but it did. i was shooting 284 286 285 285 which is damn good. all day long it stayed above 280 and never went above 288.
Buy the damn thing !!!! how could you go wrong. its light fast and the cheapest upgrade. Go get it now!
