Anyone here into firearms?

Some people have so much astigmatism that red-dot-sights simply aren't useable for them, in which case they're better off with a second-focal-plane zoom/magnified optic.

Astigmatism is usually well-corrected with accurately ground prescription lenses. Hint: your 1-hour budget lens grinder at your local mall is usually not the best place to get accurately-ground corrective lenses.

I have a G33 magnifier and a G23 magnifier mounted behind various optics, including my 4 MOA T-1, various Eotechs, and a couple of 2 MOA Aimpoint PROs. The magnifiers work great for me. I flip them down for any shooting 25 yards and farther. The G33 is definitely a significant improvement over the G23.

My t2 dot is very crisp magnified. My t1 dot was a diagonal slash. Unmagnified they were the same. T2 works very well magnified. T1 not so much.

On this rifle I got about a 2moa shift with the suppressor.

High with the muffler? With everything being the same.The suppressor usually increases bullet velocity. Which makes the bullet fly flatter.

It's not always high, I don't own a can that doesn't shift a gun a little.

Everyone I know that has a muffler, including me. All shoot high because of the increase in velocity. Usually about 150fps. Have heard of a few that the point of impact shifted left or right also.

One of my cans shoots a touch higher than the other. I believe it's straight down, though, as a whole, with this can on this gun.

What you're talking about is "freebore", and it's typically less than the variance from shot to shot in velocity increase, and some suppressors don't have any appreciable freebore effect. At the extreme edge you're looking at about a 20fps increase or so on rifles, maybe 30-50 with a pistol.

No, the POI shift has to do with changing the barrel's harmonics, and there is no written rule.

I have never seen that documented. Every single documented comparison shows VERY MINIMAL freebore boost, as I said in my other post.

I would challenge you to show this to me, this 150fps increase. As a datapoint, all of the rifles I've suppressed shoot low with the can, to varying degrees. Again though, it's just harmonic variance. YMMV of course. The 150fps increase though, is many times what I've seen proven.

Here is one example: http://www.youtube.com/watch?v=LwnG1dz0Du0

Harmonics plays a part of it too. Just never say it in the post. Sorry. Since you mentioned it. I'm going to have to check out my buddy's chrono that we used against another one just to see the difference between the two.

Out of 14 of us that have mufflers. 11 shoot high. One shoots to the left some, and the other 2, who knows.

On a side note, my Surefire SOCOM Mini has become my favorite can. You wouldn't think 1" and 1.5oz difference between it, and my regular SF cans would make a difference, but it feels like night and day out there on the end of the muzzle.

BoneZ · 05-28-2015, 05:54 AM

I don't have a rifle (yet), but I do daily carry.

I have the same can for my .300 blackout SBR. It's nice for sure!

I have the 762 SOCOM RC, and a 762 SOCOM Mini. To be honest, and brutal, I am not impressed with how they perform using subsonics in my 10.3" 300BLK. I am somewhat connected to Surefire, and I LOVE their stuff, get a few free things to T&E from them from time to time, etc. so I really hesitate to say anything negative, but the 762RC and 762 Mini really are in their element with supersonic projectiles much moreso than subs. Surefire's new 300 can, though, is amazing from what I hear, on pretty much everything. However, everything sounds sexy on cell-phone YouTube vids!!!

Truth be told, I've kindof dumped the 300BLK idea. If someone gave me a fair price for my 10.3" DDM4 upper, I'd possibly sell it and just buy a 14.5" 5.56 upper to drop on there. The whole SBR thing has kindof worn off for me. The more I train, the more I realize they are just a bunch of negatives with no real positives, even working in and around vehicles.

I guess it kind of depends on what you are going to use the 300 w/can for. I've got an AR platform rifle in 6.8 SPC with a spare 300 upper. The thought was to use the 300 with subsonics and can for under 100 yards, 6.8 for 100 to about 400 yards, anything over that to switch to the AR in 308. That's just my thought process.

I think an SBR shines in the urban environment of narrow halls and doors. I think it's easier to maneuver and less likely to get banged against doors and walls. Just my

On a side note... what would you consider a fair price?

I've been looking at something capable of deep concealed. I have an S&W 9mm shield with modified trigger I carry. But I'm an active person, my clothes are mostly fitted style and I'm constantly on the go. So it gets uncomfortable to carry in an IWV holster all the time, and to be honest it mostly lives in my glove box!!! I just want something to put in my pocket. I've been back and forth on this for weeks?

anyone have any opinions on the S&W bodyguard?

I'm not opposed to spending more cash on a nicer 380. But, being I have the Shield already and am used to the manual safety, I'm thinking it might be beneficial not change my draw process? Or am I over thinking this thing?

the others on the top of my list were
1. Kahr p380
2. Sig p250

maybe some others I should consider?

AMT Backup in 380 is a good choice for a 'pocket pistol'. There is a holster made that is a wallet style that the pistol goes in and it can be fired from inside the holster. I carried one for years, it's light, unobtrusive and holds 6 rounds. I switched to a Combat Commander in .45 for a period of time, before going to the P229 in .357 SIG. If you know someone that has an AMT that they wouldn't mind letting you wear test for a bit, that is a way to go. I think I saw them on GunBroker for about $250. There are two versions, one is DAO and has a huge trigger guard, the other is SA and has a smaller guard. I carried the SA one, round chambered, safety on (Condition 1).

Good news.

Those who are looking for TAC gun powder. Midway just got some in. I've had it on backorder since last May of last year.
