Re: What's the best upressor for AR15
Cleaning is not needed on a centerfire can. The reason that people want a take apart can is because they see that the rimfire cans are take apart and think that a centerfire should be take apart as well. Really a centerfire can that is take apart is going to be louder than a can that isnt take apart because it doesnt seal as well as a can that isnt take apart.
The reason you want to be able to take a rimfire can apart is because the projectile is all lead and a soft lead, when the powder burns it vaporizes some of the lead in the bullet. When it gets into the can the can does what its supposed to do, it traps and cools the hot gasses produced, it also cools the vaporized lead and it is deposited there on the baffles of the can.
A centerfire bullet is jacketed and think about how a smk is made, the jacket is drawn from the base of the bullet to the tip. So you really have no need to take a centerfire can apart.
As far as what is best? You really need to shoot each one and see which you prefer. Some sound better than others as tone goes. I like AAC products I have an M4-1000 mod 08 on my AR. Where the price difference in the cans is in the materials that are used, which leads to the weight and length of the can overall.
