I have a Tirant 45 can coming, and I really would like to start getting an idea of a shoulder fired small SBR for it.

Im really leaning towards a MP5K clone but am open to suggestions as this is something that wont be happening this year

With so many different options out there I wanted to see what you guys thought was most enjoyable to shoot as well as a good suppressed quiet host.

I want to keep it in either a 9mm caliber or .45acp

I think a Reverse Stretch K is in your future; then add your favorite flavor of pistol to be a companion to your SBR/Can combo and have fun.

I have an MP5 Pistol from Turner Fab and an HK45-T, but still waiting for the Octane HD 45 with 3-lug adapter... (saving the money for it)

Im really liking the idea of a MP5K. I also started thinking really hard about the stretched K but the more I see them on the net the more it makes me wanna go with a regular K receiver. I really love the idea of the 3 lug mount.

Do you have to change out locking pieces when suppressing the MP5K? If so can I still shoot reliably without the can?

Pistol I have lined out. Just wish the forms would get here

AFAIK, with the Octane, all I would need to swap is the pistons 16x1 LH for the HK45-T/USP45T and the 3-lug for the MP5, which would need a fixed barrel spacer in lieu of the piston.

Correct.

I see someplaces from the little research I have done that it is recommended to swap out the locking piece in the MP5Ks bolt to slow down the gun for reliable shooting when suppressed with heavy 147 bullets. However I never see them talk about reliability of the weapon unsuppressed after changing the locking piece

I just didn't know if it was a real thing or simply "net talk"

Good  question. I know that on the .40 cals you have HI and LO locking pieces, according to the bullet weight (plus the fact that .40 cal is abusive on weapons like the MP5), I suggest you go to HKtalk and see what they say. There are members there with far more experience in those types of issues.

Go with a reverse stretch,  the K receiver tends to get a little loose over time.  The way the stocks attach to a K gun cause this.  The stock options are better with the stretch.  I'd recommend a B&T side folder.

Might want to take a look at the MPX as well. The AT94K I have is a blast to shoot suppressed.

Which one do you prefer if you had to choose just one?

Evo is an option as well. I could do that for around 1K all said and done it seems. That's 1K cheaper than what I have my MP5K build totaled up to.

LWRC has a new little sub gun coming out in 2016. There are pics of it in the industry forum under LWRC. I've got an Osprey sitting here that is going to go on one when they come out. No idea what the price is going to be.

The MPX makes some definite improvements(ergos, pic rail, AR safety) that are hard to beat. It's also much cheaper than my Turk MP5 clones and all the extra work I had to have done on them(chopped/threaded barrel/3-lug). The Evo doesn't seem to be a bad choice either(other than questionable factory stock options at this point), but my personal opinion on them, they look goofy as hell with the current silencer adapters.

If you want an MP5 give in and get one.  You'll always want one.  It is the Archetypal 9mm Subgun.  Like what the 1911 is to .45ACP pistols.

Top_Secret, which is quieter, your K or MPX?

I'd go Mp5 or Mp5K for nice quiet hosts, can't go wrong either way. My UZI and M16 9mm are louder for sure.

Pistol caliber SBR that would make a good suppressor host. I can see where the title would be misleading.

I bought an MPX and chopped the barrel down to 4.5", haven't shot it yet, waiting on the stamp. But, MKE just brought in their MP5 clones in again, I bought their two offerings a couple of years ago and SBR'd them, big favorites at the range with new shooters and me!

Id be really curious if one was quieter than the other with the MPX being piston driven

Which one do you think you will enjoy more when you have both up and running?

Yea after looking at the wacky thread pitch the evo uses Im throwing it out.

The MPX does seem to negate the one thing Im worried about having to deal with on the MP5K, which is not being ammo sensitive, or atleast that is what some of the reviews of the MPX are boasting.

MPX just as quiet as the MP5K?

How about building a 9mm AR.  With the JP 9mm SCS, and a TROS 3-lug barrel, the build below is dang accurate, and loads of fun to shoot.

QC10 had 20% off their lowers last weekend. If you shop around sales you could put together a pretty nice 9mm SBR built on one of their glock or colt lowers. Depending in parts you choose you'd come out less than cost of SBRing a mpx and can build different length uppers overtime if you want a small K style upper or a SD style upper with the suppressor slipped under the rail. Magazines are also less expensive than the mpx. Luckily lots of options nowadays. Patriot Ordiance Factory (US company) is supposed to come out with their 9mm ar pistol that looks like it could run a side folding stock and msrp is supposed to be around 1k.

This is an interesting development.

Im thinking a side charger upper would go nice such as this one

http://www.americanspiritarms.com/upper-receivers/asa-ar-15-m4-side-charger-upper-receiver-without-carrier/

I wonder if the side charger would make the weapon louder when suppressed however

I've got an Atlantic Arms MP5K clone that I form 1'd.  It works great and runs like a top with my Tirant-9 3-lug:



I've also got a Vector Mini that I form 1'd as well.  I got a 3-lug adapter from TROS and had Adco cut and thread the factory barrel.  I'm ashamed to say I haven't shot it yet.....



ETA - 3 lug is the way to go on 9mm carbines.  It's very handy and I've had zero problems with mine.
