The NEXGEN2 DEFENCE (WWW.NG2DEFENCE.COM) MZLMAX AFD (Advanced Flow Dynamics) muzzle device uses a unique method to keep muzzle blast, recoil and muzzle flash under control.  The MZLMAX AFT is made out of 17-4 stainless steel and comes threaded for 5.56 (1/2 – 28) , 7.62 (5/8-24) and 9mm (1/2-28).  Designed to increase safety by directing the muzzle blast away from the sides and directed forward in a way that also reduces felt recoil, muzzle flash as well as keeping the muzzle in a neutral alignment.

My first impressions after receiving my MZLMAX was its great fluting design and overall shape.  It has a very unique look that was spotted right away by friends who interested in what I was testing.  That and its weight lets you know that what you have is a well-engineered accessory to your rifle that was made to last.  The NG2 logo and MZLMAX .223/5.56mm label are well designed to let you and others know who made this great product.  Ports for the gasses to be released were machined to perfection with no signs of burrs and the overall finished was in black Nitride.

Installation was easy.  Remove old flash hider and crush washer.  Install the MLZMAX using the new crush washer provided and your off to the range to shoot!

I installed the MZLMAX on my SIG 516 rifle and brought it out to the Teams training.  My first time using it was shooting indoors in a shoot house doing room entries.  I entered second and was shooting a threat target right after my partner.  He was using a SBR with a device attached that directs all gas forward.  He shot, then I shot.  Afterwards, the observers upstairs told us that as far as overall noise goes, the MZLMAX was noticeably quieter than the SBR.  I am taking this as due to the multi-directional porting of the gasses.  I noticed a smoother shooting rifle during the time spent clearing rooms.

On the range standing off-hand, I noticed that the rifle shot very well.  Quieter on the user side and no complaints from the guys next to me.  The ones that are using muzzle brakes that port to the sides are always sent off to the far corners of the range.  No worries if you’re shooting standing, kneeling or prone.  Gasses are directed away from you.  No issues at all with MZLMAX!

A great rifle to begin with was made even better with the MZLMAX.  After hundreds of rounds down range I couldn’t find anything negative to say about it.
