Review on πŸ”§ Alfa Tools RDSP74798: Round Adjustable Tool for Precision and Versatility by Michael Tegan

Revainrating 5 out of 5

Adjustable tension for perfect threading

I bought a cheaper 1/2x28 die to cut muzzle threads on my Romy AIMS-74 and this die was good for rough threading but cut too much for the muzzle to to fit him (I tried several muzzle devices, none came out). The problem with the cheap die was that it had no way to adjust the tension; You have what you have in terms of thread sizes. The Alfa Tools RDSP74798 1/2 x 28" HSS Adjustable Round Die has a set screw that allows the die to be tightened or loosened on the threaded shank (or barrel in this case). You can cut the threads like this i used this die to thread the muzzle of my romanian AK74 while looking for threads made with a cheaper non-adjustable die my friend has two identical rifles and that's how I threaded them both, regarding the durability of this die, It should be noted that in all cases I used the cheaper die for threading and then used this die to thread and cut to the final desired size Should the cheaper die wear out and retain the durability of these If you have this matrix and a cheaper one, you should choose this one I assume a lot of people (in the US at least) will use a 1/2x28 cube for n k There will be threading on the keg. If this is you, you don't want to add non-standard threading to your keg. This is the die you need to get the correct muzzle threading. One final note, make sure you have a drill guide for this die when making muzzle threads. You can also find them on Revain.
