This item impressed me so much that I had to drop everything and write this review.  If anyone has ever tried using a photo-etched replacement muzzle brake (as in the ABER set) you know how difficult it is to get it to look right.  I usually use the PE part as a template to drill out the plastic item.  Not with this one!

It is machined aluminum with an excellent rendition of the locking nut at the base of the brake.  While other companies have been able to do this, the impressive thing is the very small perforations on the side of the brake itself.  

Actually, maybe I should take a star away since they only included four of the five rows of vent holes on each side.  Not!  Goodness, the difference is visible after installing to the mantlet.

You will need to drill out the mantlet on the 7TP kit a little to ensure a tight fit.  I will pull out a RPM/Mirage/Tom wz.36 gun kit and see if the barrel is adaptable to that model as well.

Please note that the price is for buying directly from Poland.  It is available from wherever Armo products are sold.
