| so im working on a new build in 6x45 for a target/hunting gun and while looking at parts saw adjustable gas blocks and decided i want one. unfortunately i have already bought a yhm folding sight gas block and its too late to send it back. so i got to thinking if it would be feasible to install the gas tube and drill through the side of the gas block and into, but not through, the tube, tap and install a set screw. if i do this it will be with a screw size small enough that it will drop into the end of the tube to minimize structural integrity damage. what do you guys think? feasible or just gonna mess up a tube and block? |

Making your block adjustable, ( I have done a few, be careful and watch what you are doing )
will help with this: reduce wear&tear and reduce felt recoil for my wife and nephew. Along with the other components to help with the same goal. Don't see how it will help in the accuracy potential. Unless you are really recoil shy. A 5.56 doesn't have much recoil at all. I expect the noise is what makes people flinch. A GOOD barrel, and Trigger will give you the accuracy. |

im theorizing here but i have a 20 inch long barrel, so im thinking that by restricting the flow of gas i can slow down my action cycling until the round has exited my longer barrel (less movement of the rifle while the round is in the barrel, same theory behind trigger stops as i understand it). and for inexperienced shooters like my wife and nephew reducing the felt recoil we all know will help to keep flinching and other bad habits forming, so for them it wont improve the rifle as such but they will be more comfortable with and therefore more accurate with that rifle. plus since im using a wildcat cartridge im not sure what the pressure will do. it may turn out that by occluding the gas tube at all that i dont have enough pressure to cycle the action or (if i handload my rounds hot) have so much pressure the the action is bashing itself and shortening the life of the rifle
maybe i should add some info on the rifle, its going to be 6mmx45 with a 20" barrel from black hole weaponry with elliptical rifling. MI free float handguard with a JD 4.5lb adjustable trigger and a magpul fixed stock and ar-stoner competition muzzle break |

If you hand load Hot, and set up your system for that. Bolt carrier( light weight ) heavier springs, and buffer. Then set up your adjustable gas block to make that your optimum. It very well might NOT function with reduced power loads. With a system like that it's normally set up for one particular round, and left alone. Unless you are going to carry around an Allen wrench all the time.
If your rifle will be using different loads. You then set it up for the lowest power load you will be using. It will surely work with the hotter ones. I believe Polygon rifling, is the correct term. |

I guess the worst case is you trash the YHM or make the weapon unreliable.
If your wife is that recoil sensitive maybe a tricked out 10/22 would be more appropriate. I would be surprised if any boy that wants to shoot would find an AR a problem. Mix some dummy rounds in the mags and work with them to control flinching if it is even a problem. |
yeah polygonal is the term im used to from my glocks but BHW calls it elliptical and from their drawings it is different from normal polygonal rifling. and for a tricked out 10/22 already done that but i want a rifle that she can hunt with, and i am sad to say she doesnt like shooting my 5.56 carbine because of the recoil but since she had never handled a gun before we got together maybe not all that surprising. and my nephew is 4 so the 22 to start and when he gets to 5/6/7/whenever i deem him worthy to up the ante from the 22 and maybe do some hunting with me

Trigger time is what counts most.
Put the same optic on the 10/22 as your AR and a pistol grip stock. Not the same, but close for training. Or even hook her up with an AR in 22LR. A little small game hunting and she will probably transition just fine for larger game hunting even if she never wants to bench shoot that much with a center fire caliber. Almost no one notices recoil when shooting at a live target. |
