Excellent MB


This is one cool looking and functional muzzle break. Loud but worth it. Don't waste any more on a muzzle break. Works verry well and looks awesome to boot. The price can't be beat for the functionaly of this item. have used MB's costing 3 times as much and sold them as fast as i could. One happy consumer here. PS thanks for the sticker PA!

5M1 Brake


Added the 5M1 Break to a carbine build I put togeather as an instruction rifle for when I teach tactical carbine courses. This brake is slim and sleek and doesnt add too much bulk to the rifle. It does a good job of reducing muzzle climb and recoil without the annoying gas blasts to shooters next to me. It does increase noise levels a bit, but thats to be expected from any brake. Quality of product and delivery/service from PA was top notch as usual.

Excellent Compensator


After reading the other reviews here as to how well this compensator reduces muzzle climb and recoil, add me to the list of those who agree! Second, it looks good. The finish is more of a flat dark grey than black. It matches my barrel finish. Last but not least, it's priced really low for the quality. Primary Arms offers the best products and prices.

Another good product from YHM and PA


As expected, a quality brake from YHM. Fit and finish look good, well milled and finished to match most barrels. Included crush washer ensures you can time it right.Definately a good product at a good price.

Look no further


Beyond Primary Arms fast shipping and excellent customer service, this YHM brake was everything I could want for one of my 5.56 builds. reduced recoil, looks great and didn't break the bank. I come to realize unless you want to throw money away or just wanting bragging rights, this is all most will need and a great price point. I will be ordering more in future and both Primary Arms and Yankee Hill Machine are great companies that have outstanding products.

YHM Phantom


Cannot go wrong, best come/flash hider on the market and the price is same!!! My third yankee hill muzzle device and 100% satisfied

Looks great


cant go wrong for the price!

Excellent Service!


Competitive pricing, seamless order process and fast delivery. Primary Arms just gained a repeat customer as I plan to purchase additional AR mods from them in the near future. Great job and keep up the good work!

Works well


Does reduce muzzle rise, does also increase the volume of the rifle. Not in a terrible way, didnt notice much difference as the operator but standing near it when it goes off you can hear the difference. Its well made, looks beautiful, and does the job. Heck of a deal at the price

looks good


finish & machining look good. haven't shot it yet to be able to tell if it works as advertised.

best value around


Finish wasn't great but still 95%. And for that price that's nitpicking. Great value.



Good looking part- Great machine work from YHM. I am sure I won't be disappointed by the performance!. Great service by Primary Arms with the fast shipping!

Nice upper


Good quality nice look

YHM=Good stuff

Fast shipping!


Great price on the YHM brake! Fast shipping! You can't go wrong buying from these guys.



Great price top quality. Works perfect what a difference from OEM flash hider. Faster follow up shots.

YHM brake


Great product & a good price

Yankee Hill Phantom Comp/brake - 5m1


Great product. really keeps the muzzle flip down and increases the speed at which i can accurately put shots down range..thanks for the stickers and fast shipping. primary arms never disappoints

5m1 comp


Havent had the chance to use this yet but have heard alot of great things about it. Wish pa offered a shim kit though seeing that the crush washer does not allow correct compensator alignment

amazing upgrade!


High quality and the price is great. I've tried many comp/ breaks and dollar for dollar we have a winner. Great muzzle rise reduction and recoil is very mild compared to A2 flash hider. Warning your rifle will become ear deafening loud!!!!! Double tap like a pro and buy this comp/break

Great coMp


I am very happy with my yhm comp. does exactly what a comp is supposed to do but at a fraction of the cost of their competitors.

Great brake without braking the bank!


I bought an M4 non-NFA a couple years ago that came with a pinned Phantom flash suppressor to make it legal, and I liked the performance of the YMH products after owning that for a while.When it came time to put a brake on my Rainier 3gun barrel, and Rainier was out of theirs, I had to go looking. I read the reviews of the YHM and so I figured I'd give it a shot, as I was also building a truck gun I could put it on if it didn't work.But the brake works quite well, no louder, longer or heavier than an A2 flash suppressor, and only a couple bucks more. I don't know why people would spend $150 on a brake...Also, I think a Gem-Tech suppressor will work on it too, but I'm still looking into that.

Great Break/Comp for a great Price


I have this same break on another rifle- works great and definately worth the money

Great item great value


I really like it so far no problems with installation looks good and seems to help with muzzle rise. The service was great no problems fast shipping

Awesome Product


living in the Great Peoples Republic of New Jersey. One of our requirements to be legal is to change the Flash suppressor to a Muzzle brake. The Phantom Aggressive looks GREAT on the end of my AR's, and are very reasonable priced. Will be ordering more for future builds.
