I ordered the Print XH RBS but likely won't have it in hand for another week or so. I've been trying to go with the newest because suppressor designs have been advancing so much in the last 5 years. It's really light, the latest RBS I've heard good things about, and I also ordered the A2 / SF switchable hubs so it can be used on the A4 and MR223 uppers. When I shoot it I'll let you know.

 

Do you have a picture of the A2 /SF Hub you purchased. Also, Are you planning on using the factory flash hider or the B&T Closed tine Flash Hider for Rotex / SF 1/2x28 5.56mm?

 

B&T suppressor line confusing as hell.
What about this:

B&T Rotex V 5.56

It fits your birdcage

 

B&T suppressor line confusing as hell

I'm glad they offer a ton of options, but you need a masters degree in B&T to understand the nuances of their suppressors and all the variations plus generational updates to them

 

Have you verified that the A2 hub is compatible with the MR223 flash hider? I remember reading somewhere that there is a groove or ridge on the FH that interferes with the A2 mount. I have a 15x1 surefire war comp, but would prefer not having to remove the original muzzle device

 

The fh that came on my mr223 is just a normal fh. It won't take either qd mount. I bought a 15x1 warcomp too but can't bring myself to change a stock 223. So I'm just going to shoot my a4 and a1 and leave the 223 alone. Honestly the a4 is absolutely perfect anyway.

 

Both of those suppressors are over 7” long which is be weary of. The new XH is interesting, but I’m always paranoid about durability of anything with titanium in it. If you can get a good deal, then I guess either works! But B&T seems to throw out new cans so frequently and some of them are not very good sounding. I’d almost urge you to consider something like the Lazarus 6 which would be similar specs and Juicey Media just torture tested one on a MR556a4 11” with 2500rd using the SOCOM firing schedule and it held up great!

I'm trying to address several comments in this thread --

I also considered the Rotex-X or V (that someone else mentioned) for additional European flare but at 22 ounces, thereabouts, that's a ridiculous weight to add to the front of a piston driven gun in my opinion, and they aren't flow-through. The Print-X Rotex is different from the Rotex-X & V and is much lighter. Also, (S)RBS designates that the model is a flow-through suppressor. I’m trying to help clear up some confusion for other users. Lol When you see a S before RBS, that designates it as a slimline model.

I went with the SRBS 556 ti that was offered prior to the Print-X changeover because I prefer my suppressors to look like suppressors instead of a ribbed condom. Slimline, Reduced Backpressure.

The B&T A2 Hub is compatible with the MR556 A4 flash hider. Do note that it's a heavy mounting solution. Currently my can is sitting at my FFL so I can't speak to performance but at 7.2 ounces without a mount, I'm looking forward to the reduced weight compared to my Sandman-S that I've had for years. I opted for a Rearden mount and brake. Suppressor, w/Rearden mount and brake will come in at less that 12 ounces combined. I'm not sure you can get much lighter than that.

I considered staying with the SureFire style mounting system but they have a lengthy track record of gas leakage around the mounting surfaces and carbon locking on the muzzle device. I would highly suggest taking a look at the SRBS line in either titanium or inconel.

Between the two you are looking at, I would give a nod to the B&T PRINT-XH RBS 5.56 as long as you’re ok with the ribbed condom look. It has flow-through qualities and it’s lightweight. Win-win. A photo of the SRBS 556 ti, prior to the Print-X changover, is what I attached below.

 

Anyone know which HUB mount comes on the Print-X Rotex 556 Full Size?

Surefure hub is what I show. Same as what my SRBS 556 ti came with, pictured above.

 

I'm considering replacing the M4-2000 I have on my MR556A1 10.5" with the Print-XH RBS Blk. The gas block I have is vented but I'm sure it in no way bleeds gas like the adjustable A4 gas block. I think the A1 would run better with the (RBS) can. I guess it's all about having the $$$$ to buy it.

 

After a bit more research and looking online, I think I might be leaning to the SRBS 556 Inconel Blk. It's 14.4oz and has 100% 718 Inconel so she can handle higher rates of fire and take the punishment. Just wish I had a dB reduction rating for it and the PRINT-X Rotex 556 Full Size for comparison. Also, wondering with the A4's adjustable gas block system how much gas I'd get with the Rotex compared to the SRBS? I know the Rotex would have more gas over the SRBS, but would the SRBS be worth giving up the reduced sound reduction over the Rotex?

 

B&T USA | XH-556 SC Suppressor

The XH-556 SC merges a compact 3-D printed titanium tube with a robust 718 Inconel blast baffle, tailored for high pressure demands of 5.56/.223 firearms

bt-usa.com

I believe this is the sweet spot out of over 600 BT suppressors. There are two versions long and compact.

For the doubters. The weight savings is on the outside and the Inconel is on the inside.

 

Man B&T changes their suppressor line up quicker than new smart phones get released, it’s unreal. For what it’s worth, I use a B&T Rotex compact 5.56 and the 3D printed can is incredibly light and performs great. I think ant B&T can you’ll be very happy with

 

Well, I pulled the trigger and purchased a B&T Print-X Rotex 5.56 Full Size in Black for my A4. I'm now looking at replacing the M4-2000 on my MR556A1 10.4" barrel w/vented gas block. I'm looking at going with the B&T SRBS 5.56 can. I think even with the vented gas block the SRBS would be better suited instead of the M4-2000. Thoughts?

Thank goodness. I thought I was the only one. It's mind boggling and hard to find information on "discontinued" suppressors.

I just picked up an MR 556 A4 11" this weekend and am looking for a dedicated can.

Question - My understanding is that the gun requires a reduced back pressure suppressor. Is this correct?

Criteria - I want to keep the suppressor short and light

Much like the OP, I have two ideas in mind:

Option 1 - "ROTEX 556 C"

Pros:
1. Lightweight/short
2. Comes with HUB adaptor
3. (Relatively) inexpensive

Cons:
1. Will have to buy a Surefire muzzle device
2. Several unknowns & difficult to find info on it (see questions below)

Questions:
- Is it full auto rated?
- Is it reduced back pressure?

Option 2 - "Print XH RBS SC 5.56"

Pros:
1. Latest technology
2. "Free" tax stamp
3. I like the color better (I know it's a lame reason)

Cons:
1. Direct thread
2. Will have to buy HUB adaptor and muzzle device (A2 device seems heavy)
3. ROTEX?/SF HUB adaptors don't seem to be readily available

I've been pulling my hair out trying to figure out the B&T naming convention and get specs (weight, length, etc) on some of their products.

Any input would be greatly appreciated.

The Rotex is full auto rated but it is not reduced back pressure. I just purchased a full size Rotex that is black. I think the MR5556A4 with the adjustable gas block can handle regular non reduced back pressure cans. The HK416 vented gas block upper I have on my MR556A1 on the other hand really needs a reduced back pressure can. The MR556A4 will not even cycle without a can on the suppressor setting as the A1 will cycle without a suppressor.
