If we were to compare your Matrix to the Ego for instance, the Matrix is running a heavier bolt aligned and separated from the breech by several o-rings. That eliminates direct contact between the bolt and the breech, reducing breech wear, but introduces drag and slows the bolt cycle.
No big issue, as the Matrix wasn't designed to have the absolute highest cycle rate.
Egos on the other hand - even more so in early iterations - were designed with very high cycle rates, and so have short, light bolts with no o-rings. That allows for the cycle rate to be maximised, but does make breech wear more likely.
Basically, if you want the Ego's features and performance characteristics, you have to accept the consequences of that design, or switch to a bolt that runs on o-rings, but accept that there will be some additional drag, and that you'll lose some of the cycle rate that the Ego is known for (though in capped play, that probably isn't going to be an issue).
so this might be old new im just look at it thought so its new to me.
so here is thing if you have an internally contained system such as a spool vavle it is in less danger of outside elements such as dirt. so it does have oring but that does lower cycle speeds at all and there is also less breech were cause the is less direct friction. now in the case of most poppit vavle guns they have open bolt with a delron/plastic bolts with no oring not to increase cycle speeds but because the orings would get torn to shreads with the amount of dirt that get in there. there will always be breech wear on an open bolt gun cause it a larger surface area of friction with dirt between the to areas. and if you want to aruge the cycle rate thing why does dm13 cycle just as fast as a ego/boblong etc. of the same year. and thats why the fastest cycling paint gun the karnivor had oring on the bolt.
