Re: Intregal 77/22 barrel, suppressor drop in?
..
You asked a question. I will paraphrase that question for you "Why do many sell their integral only as a complete rifle?" The short answer is that many shops buy complete rifles and, because an integral requires the barrel, they use the one that came with the rifle. Others buy seperate barrels and they can and do sell them as "seperates." A warning, the real work in fitting an integral, say in the Ruger line, to the chasis is at the forearm, many try liners and original diameter barrels to avoid recutting the forearm. I have yet to hear one worth a piss. Each and every one I have heard over decades is poor. A larger diameter (Bull Barrel) integral is the way to go....and they take work. Also know that on the 77/22 ( a great host because of its bolt and lack of action noise) Ruger has moved to a threaded, not block and thread attachement of the barrel to the receiver.
There are many difference between a blast can and an integral barrel, but one of those differences defines the integral. That is...the ability to take a supersonic projectile load and lower the velocity to subsonic PRIOR to the time the projectile hits the blast can component. In other words, an integral must work with "full load" rounds and be tuned to make "full load" rounds into subsonics. Anything welse is a FAIL. For that reason any good integral manufacturer will recommend a velocity to use in their integral product. Why? Because the ability of the designer to insure MAXIMUM sub sonic velocity is the goal. To do that, the port (the best intgrals I have seen in .22 have a single tuned port) must be sized specifically for that full load. Will other velocities work? Perhaps, but MAXIMUM subsonic velocities are made possible by tuning.
A blast can, in any diameter, stuck on the end of a standard no tap barrel is not an integral...but rather a "dedicated". Integrals tap gas.
When I see an integral being shown shooting subsonic ammo as if THAT makes sense, I laugh. Its a joke, its complete and utter nonsense. When one loads a subsonic round in a rifle you do not need to waste your time tapping gas off, right? Its subsonic already! Your going to do what? Tap gas? All one is doing is clearly showing is that they simply don't get it...and, perhaps...their barrel isn't tuned and that their blast component works best with as little gas as possible. Bullet stabilization? In a subsonic that is having its gas tapped?
This is what I am talking about...shooting subsonics in an integral.

What we want to hear is that very integral rifle do its job....be something other than a blast can...tap gas, reduce a full load to sub and BE AN INTEGRAL. I can look at the diameter of that barrel...that integral barrel and know...nope.
The best way to think about an integral is....a dedicated subsonic rifle that shoots specified supersonic rounds. What do you get when you do this?
A great blast can component that can handle the gas..
As close to transonic as you can go, maximizing the potential power of the round while still being subsonic..
In a bolt gun, a rifle so quiet as to actually allow you to hear the firing pin and sear go off.
The quietest 77/22 integrals I have ever heard are made from a company that does not sell the integral/barrel seperately as they know the amount of work in preparing the stock forearm is required and needs to be done properly. I own it, its the quietest suppressed rifle I have ever heard. If you decide you want a full rifle, come on back.
Buying subsonics rounds is expensive and they are dirty and the bullets are not plated. Its great that you want to go integral, get one worth the wait and costs.
Good luck.
