What is the general consensus on getting your Romanian Ak barrel threaded, and/or muzzle brake attatched......take it to a Gunsmith, or do it at home? What are the prices comparitively? What are the (not-obvious) pros and cons? Also... Can most gunsmiths do this procedure? Is the home-threading operation easy? Are the results high-quality? What is the best muzzle brake style,and where is the best place to buy? Should the brake be permanently attatched or removable? What are the pros/cons? |
| Home remedy. Rent the die $25. Very easy to do and looks great. The best brake is the one you like. If you change your mind get another. That's the beauty of it. I'm partial to the slant but the effect is negligable. Don't forget to order the retention spring and plunger. I can't recommend any particular vendors. Their all decent in price and quality. |

The rental charge seems like quite a fee. So I just bought one. http://www.gunbroker.com/auction/ViewItem.asp?Item=26683600 Looks like I answered my own question. Anyone have any advise on threading? I have 3 rifles to do, but I'd like the quality of them all to be as good as possible with the tools I'm using. |

I just did my Romy last weekend. It was easy to do and turned out nice. I'm just waiting on the spring and plunger to come in from kvar and it will be complete. Only advice I have is to cut the threads gradually(depth). I cut mine full depth all at once and it was hard to turn the die (duh). Here is a link to my thread if you havent already seen it. www.ar15.com/forums/topic.html?b=4&f=79&t=66466 |

First thing go to the hardware store and buy a can of thread cutting oil. You will need a vise or someone to hold the rifle. Also you will need paper towels and masking tape. Take 4 sheets of paper towels and wrap them around the barrel between the gas block and front sight in a cone shape so they look like a "V" and tape the bottom of the V to the barrel. This is so the paper towel cone will catch all the metal cuttings and oil. The die has a top and bottom. If you look at the cutting teeth you will see the bottom has tapered teeth. That is the teeth are just nubs and get larger farther into the die till they are full size. Place the top of the die into the die stock(handle) and tighten the screws to hold it in. Don't go hog wild just tighten them enough to hold the die. Place the rod end of the thread alignment tool into the top of the die and screw it in half way of the die. Squirt oil all around the outside of the barrel and insert the tat into the barrel till you feel the teeth of the die contact the barrel. The die is a 14x1mmLH which means the threads turn to the left so you will have to turn the die to the left(counter clockwise). Exert force evenly on both handles of the die stock as you turn it. You will feel the die's teeth start to cut so turn the die 1/4 of one revolution on the barrel and stop! Turn the die in the oppsite direction till you feel the teeth break the chips of metal they just cut then stop. Reverse direction and cut another 1/4 turn of threads. Then reverse direction agian to break the chips. On every revolution of the die blow with your mouth through the top of the die to remove the chips and put a drop or two of oil on the teeth of the die. This is of unmost importance when cutting threads to break the chips. If you don't the metal the teeth cut will curl around and get between the teeth and barrel. This will result in them tearing up the threads you just cut. Repeat the cut and reverse to break chips till you have cut all the threads you can and the die stops aganist the front sight. Due to the taper of the teeth on the bottom of the die it will not cut threads all the way to the front sight. Screw the die off the barrel and reverse the die in the stock. Screw it back on the barrel and cut the last thread or two next to the front sight. The Number One rule with theading is you can't use too much oil. Once you have the barrel theaded keep the rifle upright and hold it over a trash can while you remove the paper towel cone from the barrel. Trust me on this one if any chips fall on the floor and you step on one barefooted it will cut the crap out of you and imbed itself in you skin. |
