This product is legit
I put this break on my SAM7 and it worked very well. A very noticeable reduction in recoil and it looks badass! Would highly reccomend.

The RRD-4C-S (slim) retains all of the positive attributes of its bigger brother: Reduced recoil, reduced muzzle rise, and reduced flash! Even with its reduced size and weight it still remains very competitive with other "Big Box" companies while having a more "streamlined" appearance.
RRD-4C-S muzzle brake compensator is:
23% slimmer (.885" vs. 1.150")
35% lighter (1.8oz vs. 2.75oz)
Product Specs:
- Threads: 14-1LH
- Material: Military Grade 17-4PH Stainless Steel
- Length: OAL 2.1"(53.4mm), Added length 1.5" (38.1mm)
- Weight: 1.8 oz, 51 grams
- Finish: Matte Black Nitride
- Caliber: 10mm bore will work with 5.56, 5.45, 7.62x39, 9mm
- Manufactured in the US and counts as 1 922r compliance part
- *Not intended or recommend for barrels shorter than 10.5” (see below)
*When testing these devices, we found that high rates of fire such as full auto or “mag dumps” could cause damage to the device due to the excess heat, pressure, and gasses from unburnt powder on shorter barrels.
Compatibility;
- Russian, Bulgarian, Hungarian, East German, Polish, Romanian - AK, AKS, AKM, AKMS
- Yugoslavian/Serbian M64, M70, M72, OPAP, PAP
- Chinese Variants with 14mm threads
- US AK/AKM clones - Century, DDI, IO, etc.
- WILL NOT FIT VZ.58 and its variants
Since the release of the original RRD-4, we have been tweaking the design to improve muzzle control and reduce weight. The RRD-4C has cut-outs on the top sides to allow gas to vent upwards in turn forcing the barrel downwards and virtually eliminating muzzle rise with an extremely low flash signature!
Additional Pictures can be found HERE!
* Reduces flash on barrels 12" and longer.
Muzzle brake 4C 14-1LH Slim
Great device and high quality as always.

Contacted JMAC about which muzzle device is best for a Zastava M77 .308 .... got a reply within 2 hours. It was this one or it's bigger brother. Very pleased with fitment and finish of the 4C 14-1LH Slim , reduced recoil, and ability to follow up shots much better. Excellent customer service, product, and shipping time .... many thanks JMAC !!!
Muzzle break
Seems to be built well. It was a little tight when installing but no real issues. Feels like it took away 50% or better of the kickback compared to factory muzzle break. (Installed on a PSA ak-47) Very happy with it. Price was good, bought with a free shipping coupon too. Go Trump!
MuzzleBrake for my m90
Bought the slim for my Zastava m90. Gotta say holy sh*t! Basically no recoil. Love this thing and so glad i went with jmac. Now i want to buy another rifle just to buy another muzzle brake from them, hahaha!
Reviews
The device helps set up quick follow shots and greatly reduces recoil of 7.62 and 223 5.56
Awesome Obvi
This looks incredible on my Zastava M90! I searched and searched and found this muzzle break. It is awesome, helps with recoil, and the sound is poppin! Love having a JMAC piece on my rifle!
Muzzle brake
After watching klayco add one to his m90 on YouTube I wanted to give one a try. It absolutely turned my m90 into a laser beam with 77gn bullets. It shot 3/4 in groups at 100m. I'm 100% happy and amazed at this product I'll be buying another for my m70 and Polish underfolder.

RRD-4C slim
Awesome muzzle device. Really tamed the recoil on my Zpap M70. Fast shipping, great customer service. Will continue to buy from Jmac. Love their products.
Awesome
Big upgrade from slant break. Put just over 200 rounds thru it so far. I'm impressed.
RRD4C
I have not had the chance to shoot with it yet but as with anything JMAC Customs makes I expect it will perform above my expectations. It is well made and light weight, definite care was taken when it was machined.
RrD 4c slim
I have 3 of these and they are top notch Fit finish and machining is perfect and they reduce recoil on the overgassed AK rifles

Beast muzzle device I’ve tried. VERY noticeable recoil reduction.
Muzzle break
Only put around 200 round but work great so far
RRD-4C 14 Slim
This muzzle device looks fantastic. It functions well, aggressively diverting gasses to either side of the shooter. It makes a noticeable difference in horizontal deviation. Would recommend, especially for shooting outside.
Seems good
Went right on the gun no hassle and does what it says
4C slim
Great Quality and finish! Fit right on my Norinco 84S pre-ban in 20 seconds! Looking forward to trying it out when the ranges finally open in PA.
Outstanding product
Great break! Excellent fit and finish!
