This is exactly why people need to DO THEIR RESEARCH before they start monkeying around with their stuff. A knowledgeable gunsmith/armorer would not have just cut down the barrel without also opening the gas port to the correct dimensions. What baffles me even more is why you cut down a 16" to begin with and then had someone weld a large flash hider on there making it longer.
I am almost certain that if you were to replace the barrel (which I highly recommend) with a good 16" barrel it would start to function properly.
I would also look at getting some other types of ammo not weak stuff and seeing what happens as well.
agree with iraqgunz- also the FIRST and LAST rules with any weapon system but especially with ar’s and 1911’s in my experience-if it works leave it alone- no other 2 weapon systems see more failures come from efforts to “fix” what is not borke!
yeah, ill agree, that was a retard move on my part…i put my “ar” upper on the mill, and milled out the gas port, and it works fine now…thank you for everyone’s advice
