its amazing quality for delrin and smooth internal wall
Weaknesses:
may possibly swell because its delrin?
Review:
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 .
Conclusion:
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

Strengths:
Its super slick and weighs half as much as the stock piece.
Weaknesses:
You need a different size o-ring on the bolt sail.
Review:
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.
Conclusion:
Buy the damn thing !!!! how could you go wrong. its light fast and the cheapest upgrade. Go get it now!
