We really live in the “salad days” of the Suppressor ownership, whereby the competition holds the prices relatively low and the (immoral, unconstitutional) NFA approval process is moved as quickly as always. In fact, today's review, the M4SD-L Griffin armor, was approved in about 18 hours as soon as the F'ing ATF had the paperwork. Apart from state grips, we look at the M4SD-L how it works and what it makes a recommendation.

I would argue that there are four main considerations if we look at a modern purchase of suppressor. Physical form (which includes both size and materials), back pressure, assembly system and overall suppression. Let us tackle this if you refer to the M4SD-L grip. The price depends on the situation of every customer that I am worth the reader for you or not. I report how it works, you decide what you want to spend.
Physical form
It is 6.5 inches long and 14.5 ounces steel. The M4SD-L is not a micro box, and it is also not an overkill can for maximum oppression. I would say that the M4SD-L falls into the “medium-sized” category and against the smaller end of this genre. This is a pretty short suppressor, but it is extremely solid, which is for the “swabless, laser -welded” quantity. Not as easy as a titanium, but lighter than many other suppressors in this length, this diameter and in the price range. Going tubeless helps to save weight, at the expense of an increased welding time/costs.
Back pressure
This is a subjective category, but the comparison helps us here. Griffin Armament uses Eco-Flow-Gleitlechen on the M4SD-L, which offer better oppression than the entire “river through” singers and better back pressure reduction than conventional guide sheets. Here is a short and informal description of Austin, owner of Griffin Armament, which took place in a discussion about AR15.com about eco-flow baffles:
We have a few patents on the cans. They use basal connections on the periphery of the guidelines to create streaming vertebrae and put a variety of gas flows into contact with other flow flows at high speed. The turbulence generated by the additional flow through gas reduces the gas speed and reduces the energy, lowers the sound and improves the river through the system.
How well does it work? Well, pretty pretty as I expected from the design statement. While the Griffin Armament M4SD-L has more back pressure than the Huxwrx Flow 5.56 TI I Next to it is a clear improvement compared to older constructions with traditional control sheet, such as AACS M42000, suppressed armor system Reaper Ti and even the M4SDII grip. There is not a lot of gas back to protect after it has tested this can for a few different hosts.
It is worth noting that Griffin Armament also designs her MKII AR-15 series in order to further alleviate gas for the shooter.
Montage system:
Griffin Armament uses gate-locomotive assembly system that is immediately known to anyone who has used KACS M110 or QDSS-NT4-Suppressors with their gate Latch Mount, which the gate-locomotive design has quite clearly influenced.
The Suppressor page of the assembly system has the gate that is lifted out of the suppressor to release it or presses to include the bracket. The gate is held by a spring plate on the spot that has to be pressed out of the way (backwards) to release the gate.
On the rifle side, interfaces of the gate-locomotive interface with the gate-locomotive series from Griffin Armament of Flash-Wishers and Compensators as well as standard USGI A2 flash-hiders. However, this last object needs a little more clarification. Not all A2 flash -hiders that have a full effect on the specification, since some manufacturers seem to find that they are only used as lightning tasters. For this reason, some of these A2s do not properly assemble an empty fire adapter.
While you can be free with which A2S other M4SD-L owners have achieved different A2S owners (DEL-TON, according to some Reddit users), Griffin Armament also contains a hammer componer with the suppressor for use on your 1/2 × 28 co -binding.
My first days with the M4SD-L and the gate-locomotive mount were frustrating. The tolerances between the can and the mount were quite tight, so that some were wobbling and twisting. After installing and removing the can about 25 to 30 times, the entire system was significantly open.
There was also a small learning curve about how you can arrange your hand exactly if you remove the can to keep you a single -hand job. I was sure I was screwing up something, and now everything is running smoothly. This has turned into the fast and simple assembly system that is advertised, with less wear/outline points than a locking system (AAC 51, 90-tooth) and no chance that the carbon lock will turn its bracket in its can (SAS-Grab ) (SAS-Grab). . This is particularly practical if, as a reviewer, I often have to replace the brackets for various rifles and do not have to use thread blockers on a bracket that only goes on the rifle for a few hours.
Griffin Armament also offers the gate-locomotive assembly system for lifting interfaces if your purchased or constructed suppressor for hub-compatible modular assembly systems enables.
oppression
Finally we come to the big one. The overall impression is the greatest factor that most people will take into account when shopping for a can. Without extremely expensive test machines, I rely on some experts for the objective part and my own ears for the subjective side.
Firstly, you may have found that Griffin Armament has listed the following in the Tech Specs section: “DB evaluation:” (133.7dB) 11.5-in. Griffin MK1, (131.7 dB) 16-in. Griffin Mk1 ”. Here is a manufacturer that has provided a video about tests and comparison with two other cans.
It is a really good start to get one .223/5.56 under 135 dB, but I understand that some people who are available are not convinced. So we continue.
For those who know, the Summit Summit is a large industry event in which a fairly large number of industry experts come together to test their cans in a standardized environment. You can find an interesting discussion about the Summit Summit here.
The test results for the M4SD-L can be found here in the results of the 2024 silencer summit together with dozens of other doses. I have the data analyzed to the desired degree, but here are some remarkable doses that the M4SD-L in MIL DBA AVG (average decibel level using MIL-STD-1474D tests) are beaten:
- Huxwrx Flow Ti (2.3 dB Lauter)
- Deathfire SOCOM RC3 556 (4.8 dB Lauter)
- Otter Creek Labs Polonium K 556 (4.8 dB Lauter)
- Silenco Velos LBP 5.56 (2.9 dB Lauter)
This is not nearly an exhaustive list, but this shows that the M4SD-L can definitely compete with some other popular doses on the market.
The M4SD-L grip not only suppresses quite well and has a tolerable amount of back pressure, but also that clay is there. This is definitely an unscientific measurement, but one of the first things a customer notices when shooting a can. Some suppressors have a lower, relaxed, relaxed ffwoomphwhile others will have a higher and stronger pressure Pfftft. If I have to continue my strange sound effects, the M4SD-L has a moderate high pressure sound, somewhat short and sweet ffuh. Ok, I'm done.
Conclusion on the Griffin Armament M4SD-L
In order to achieve the Griffin Armament M4SD-L, we have a fairly short tubeless suppressor that does not weigh a ton. This is a rather quiet can that she doesn't pour on a bin. The assembly system is effective, closes tight and uses dirt cheap A2 flash. The can costs 994.95 US dollar from Griffin Armament or 896 US
So is it worth it? This is for every customer who decides based on his own budget, but this is definitely a strong artist in terms of oppression levels, acceptable back pressure, very good if I consider the assembly platform and excellently for the size/weight a steel box excellent. I don't really see a reason to ever take these can from my rifle, so you can say with certainty that I really like the M4SD-L Griffin Armament, and I think you will do it too.
