The great thing about the S&W offering is that the whole suppressor weight consideration is non-factor due to the outer barrel portion being stationary.

[@bench175]

But it doesn't stabilize 62gr

[@MrSmith-zy2bp]

​@bench175 Why will it not stabilize 62 grain? It's a 1:9 twist rate, the same as the FN five-seven pistol.

[@bench175]

@MrSmith-zy2bp Either gas system barrel length or both. He made a Short video showing keyholing with S&W

Not exactly on topic, but how’s that DT CAOS RMR mounting plate working out for ya? Did you experience a degree of wiggle room as it pivots up and down ever so slightly on that rear screw?

[@BuffRANGE]

Been holding good but yes it does have a tiny bit of cant because of the two set screws but it has been locked down for over 1200 rds so far.

[@drewhenderson13]

I wonder if the new M&P 5.7 will cycle subs with a rifle suppressor since it has a gas operated locking mechanism and the threaded outer barrel doesn’t move.

[@BuffRANGE]

Matt I know it's been a while but in the Ruger 5.7 pistol and LC Carbine manual it says that if you are going to use a suppressor it's best to use a 5.56 suppressor on them for best performance. Great video thanks!

[@TransistorBased]

Good Lord, assuming that the microphone on the camera isn't auto ranging, The suppressed shots are around the same level as a speaking voice? I've been wanting to try the subsonic out of my short PS90, but I don't have a suppressor or any plans to get one in the near future. Even unsuppressed, it sounds considerably quieter than what I would have expected.

[@wesgyde8122]

wont be sub, even with a suppressor. they load them so close to the 1050 fps that an inch of barrel makes them go super sonic.

[@houndsong]

Who offers threaded barrels for the FN Mkii? Great overview. Thanks!

[@BuffRANGE]

Jarvis and EFK. Thats it.

[@Calqid]

Why. I bought one once and everything went as planned?

[@calangel]

If you load subsonic rounds yourself, Speer has a 70gr semi point, flat base style bullet that would be the best lead core bullet for loading subs.

[@BuffRANGE]

That sounds very long for 1:9 twist at subsonic

[@calangel]

@@BuffRANGE it's not, it's 0.808" in length. It's a pill shaped bullet with a flat base, so it has a higher weigh to length ratio than boat tails do. Easier to stabilize than the bullet you feature.

[@BuffRANGE]

@@calangel Ohh, That might be very interesting !

[@calangel]

@@BuffRANGE matter of fact, the 70gr semi point is more stable at subsonic speeds from a 1:9" twist than the 55gr FMJ-BT is. The calculators will say 1.77 vs 1.73 S.G. in favor of the 55gr, but that's because the formula doesn't account for a flat base which makes the actual stability higher.

[@Calqid]

Could one simply pull these 62s and replace with 70s? There might even be enough space to seat deeper

[@maxtheroofer8004]

Whish you would have sent one through gel!

[@0214Bub]

any issues with your 16" barrel Ruger LC?

[@BuffRANGE]

Very few rounds, can't say yet. It was beating the crap out of the brass coating, but those surfaces may have been smoothed out.

[@Calqid]

800 rds, + or - , and no issues. I have the tandemcross trigger and mag extensions. Like very much both. Do not like the folding stock, cheap/rattley and fat while folded (7/16” between gun and stock when folded). Certainly, the engineers didn’t ask for this. The only thing I can think is that this stock was for a different gun.

[@M3M80]

I would really like to see a gel test on this!

Indeed. Looks to be just a chopped version of the 16" LC, but more ideal barrel length.

[@BuffRANGE]

@@desertdwellintom I now have 2 Rock’s and have had zero failures with either one. What issues are you experiencing ?

[@desertdwellintom]

@@BuffRANGE 1. First rount failure to extract on a full mag across a range of ammos (thought maybe it was just mag break in but have stored them loaded for two weeks and am now 400 or so rounds in and still the same issues). AE, 195, 197, Fiocchi. Both supressed and unsupressed. 2. Supressed with both a Dead air mask and a Rugged Oculus I will get FTFs randomly in supers that will cause damage to the bullet seating in the neck rendering the round "unusable". This occurs roughly once a mag. 3. Obviously as I was informed from your previous posts I am not overly surprised the Fiocchi subs do not cycle with either can as they are both a bit over the 6oz mark, but I will admit to being disapointed. This is on a threaded optics ready Rock aquired about a month ago. Holosun 507k on top. Was quite suprised as most of the online reviews are all quite positive /shrug But its a Gen 1 PSA product so not overly suprised. I was looking for more info before going back to them on it but I expect it will likely be made right.

[@BuffRANGE]

@@desertdwellintom did you mount the RDS yourself? The K is directly on the slide? Did you verify screws are not TOO long? Many direct mount RDS ship with screws that are too long and have been damaging striker housing assembly.

Supersonic rounds for outdoors at the range and in the unlikely event of some sort of civil War / revolution. Subsonic rounds for home defense protect your situational awareness firing indoors.

You cannot reverse the paddle relase.

[@BuckeyeBallistics]

Interesting. These are almost compareable in caliber/weight/velocity to the Aguila SSS Sniper Subsonic .22LR, although bullet design is obviously very different being one is rimfire and the other centerfire...

does this round have the same capability as the sb193 as far as penetration? Any point in reloading SGK vs just grabbing this?

This will not mimic SB193 in that regards. SGK still the king. :D

[@agentoranj5858]

What's the application for this?

[@BuffRANGE]

Target plinking, small to mediumish game control with a emphasis on quiet ? Could be used for PP/SD as it would still penetrate 12”+ in gel but wounding would be limited.

[@Battle_rifles]

The bullet design is far better than .22lr

[@innercityprepper]

I'm no scientist but it seems like 5.7 would have better ballistic coefficient numbers because of the shape of the bullet. That said, the price is probably close to an order of magnitude cheaper for 22.

[@timewave02012]

I don't know about this bullet, but some subsonic 5.7 is capable of penetrating IIIA. So that's another potential reason to use subsonic 5.7, instead of .22lr, in addition to reliability and ballistics. Also, if you have a sealed 5.56 suppressor, you probably shouldn't shoot dirty .22lr through it, but 5.7 is okay.
