How much difference does a 4" vs 8" barrel make for...

...muzzle velocity with marginally subsonic ammo?

Assume shoulder fired with one of the stocks and red dot sight.

In that video MAC is having some major gas blowback issues. In the video below from RTN he says he has none. Wonder if suppressor and/or ammo are making that much of a difference?

i am going to chime in on the suppressor threads that i just read.

this is pasted from my comments on a silencertalk thread:

i have been reading a lot of threads about the MPX and blowback over the last few weeks. when i first got mine (8" barrel), i was very disappointed in the amount of blow back with my octane9HD, to the point i was trying to sell my MPX and/or trade it in for another toy. but when i was reading some of the other discussions (multiple times), it got me thinking. i remember reading sometime, somewhere about larger can volume and how it might help. so i took my osprey45 out with it today. i received zero blowback. i switched back and forth with the octane9 and osprey45 burning thru 200 rounds of american eagle 147 and 50 rounds of american eagle 115. most test strings were 10-15 rounds to get a good baseline and make sure i was actually perceiving corretly what was going on. when i finally determined the osprey45 provided no blowback, i did 3 30 round mag dumps...no blowback. so i took my MPX off the market where i had it listed for sale.

MPX 8"
american eagle 147 and 115
octane9HD provided terrible blowback with both loads
osprey45 provided zero blowback with both loads
all shots were taken NTCH, or as best i could do without a stock. without a stock, the recoil kinda punches you in the nose lol

so, i am now wondering if the design of the osprey with the monocore allows more gas to be blown into the can, and not into the action. i am also wondering if being a 45 allows more gas to escape thru the bore with the larger baffle openings and bore opening.

maybe in the next few days i will take my YHM cobra9 out. it has a monocore and a large bore opening. it is actually quite load compared to my octane9 and osprey with the same load.

i would love to test an octane45 and an osprey9 to see if i get the same results.

I think the blow back problem is a result of using a suppressor designed for hand gun use. I use my Octanes 9 and 45 on my handguns, 9mm AR, and MPX. Even on the 9mm AR I get gas coming back. Maybe next year, I will get a suppressor designed for subguns. Heard B&T suppressor's might be made in the US and they make one for the MP5.

SSHHHHH! Don't tell everyone. Now ALL the cool kids will want scratches in their anodizing!

Yeah, I literally laughed out loud when I read a post from a couple weeks back when someone had spoken with Sig and had been told that if they ordered the telescoping stock then, they should receive it in December. I suppose it's possible, but after waiting almost 6 months seems a bit unlikely. Can anyone who just recently received one give us an update on their order date? Thanks!

Unfortunately, if there was any new information about it "from Sig," I wouldn't trust it at this point.

I'd much rather hear reports from actual users, which is why this thread is so valuable.
