I had been interested in a Tomahawk as well, and did some homework on the company.
Mustafa Uslu run a very modern ISO 9001 factory for their shotgun. They are not "The Norinco of Turkey", but much like Tisas they make original products with consistent quality. Their products are inexpensive because they are fighting for market share and name recognition, they are not cheap due to shoddy quality like Chinese clone guns.
A lot of people scoff at "ISO 9001", but it is legit. Sig, H&K, Sabre Arms, Mossberg and a few others pushed for ISO 9001 certified manufacturing in order for consistent quality. Modern CNC, high end steel, and ISO 9001 quality control gets rid of the "is my gun a lemon" factor.
Long story short, companies like M&U, Tisas & Kral are easily on par with any american firearms manufacturer (and easily ahead of the non-ISO ones).
People used to bash "slav sh!t" from cz back in the day, and when the cz 75 showed up in the 70s there was a huge american bias towards it. "It is cheap so it must be terrible!", right? Who would want a slav pistol? Jump ahead 20 years and the CZ 75 is regarded as one of the finest handguns in the world. No one disputes the quality of the CZ 75 now, but they had to fight for years to get the name recognition they deserve.
As an interesting side note, Turkey has replaced the CZ 75 with their Tisas Zigana (also an outstanding handgun sold by Marstar, coincidently). If the Mustafa Uslu shotguns are anything like the Tisas pistols in terms of quality, then they are a steal at their current price.
I have some friends (offline) who bash Marstar for the same reason some of the people here are doing it. They see the cheap optics and the Norinco P220 clones and accuse the whole site of being "chinese trash"... but they overlook some real gems hidden in there. No one questions the quality of the Delta pistols or the MG-34 machine guns they sell. People unfamiliar with the BUL or Zigana may question them (based on name recognition) but that is their loss.
