After close to 6 years of riding the rails and debating on an M14 build, the CanadaAmmo Norc shorty M305/1000 rnd box set has officially knocked me off the fence (and into the dog house with Momma again:D), so now it's time to get dirty.

I'm not new to firearms, but I am on this platform and could find precious little on the Dlask M305 Adjustable Gas Lock... on CGN, Google or anywhere where else for that matter?

I've historically have really good luck with Dlask products so was wondering if the AGL is a good idea. This was from their site...

"The Adjustable Gas Lock allows the gas tube to be assembled on the barrel/gas system at a desired torque without worrying about going out of alignment or leaving the gas cylinder lose. Because the Adjustable Gas Lock is indexed all the time, the right amount of torque can be applied without putting unnecessary stress on the barrel and/or gas system. The nut is threaded for Norinco/Polytech barrels only. It accepts a standard front sight on the top dove-tail. CNC machined out of steel. Black finish."

So I was wondering if this would help in eliminating the need to 'unitize' the barrel, or does unitizing perform a different or additional function? I don't want to spend my first accessory dollars on a donkey of a part, but I have faith in the manufacturer based on previous experience.

Any thoughts?

Seems like it makes sense to me. I don't think it would eliminate the advantages of unitizing, but would eliminate the need for shimming. I'm sure someone with greater knowledge will correct me if i'm wrong but i seem to remember the gas lock should hand tighten to 5 o'clock, the tool tight to 6. Sometimes shimming, or stoning of the gas lock is required to make this happen. This device seems to eliminate the need for both those steps.
 
It would eliminate shimming but not unitizing(unitizing is rigidly connecting the barrel band and the gas system, it's in the stickies). If you're getting one of the CanAm shorties though, you don't really have much of a need for this product as it's main use, as I can see it, is allowing you to reuse your stock front site after having your barrel 'shortied' and then running whatever muzzle device you want. This is because the SEI and other gas lock front sights don't work with the threading on the chinese barrels. Since your barrel comes from the factory at 18.5" you can already use whatever M14 muzzle device you want without modding anything.

Basically if you did purchase this product, you'd be spending $120+ to replace shims, which, if you contact Hungry, are free...

Dude , it seems you are a little confused as you don't quite know the products you are talking about .
If you buy the CanAm rifle , if you want to use "whatever M14 muzzle device you want" as you put it , once you take the original muzzle device out, you are left without front sight (bummer!!!) . This is where the Dlask adjustable gas lock comes to offer you a dovetail where you can hang your front sight that you take off from the original muzzle device ;)

Secondly , you leave the shims alone where they are. With the Dlask device you don't have to change shims , as you don't have any reasons to change , remove or replace shims . The Dlask adjustable gas-lock tightens on any package of gas-cylinder/shims . If you understand the shimming of the M14 , you can see the Dlask adjustable gas lock is more intelligent than any existing gaslock on the market .

Third , it has nothing to do with lenght of the barrel . It works the same on long and short barrels .

I didn't say you could use 'whatever muzzle device you wanted' with a factory shorty, only that you could use 'any M14 muzzle device'. What muzzle device would you use on a factory shorty if you were to put said Dlask GL on? The barrel is threaded/splined to take M14 specific devices. To put on anything else you'd have to have the barrel rethreaded and recrowned which would require you to chop the barrel, making it to short to be non-restricted. I guess you could put the Dlask GL on and still use an M14 specific muzzle device but they all have an integral dovetail on them for a front sight, the use of which would give you a longer sight base than using the dovetail on the Dlask GL. All this bringing me back to how in this case, it is a $120+ replacement for free or practically free shims...
 
If you read the stickies you invoke here , you will see that the primary function of the shims is to align the gas port in the barrel with the gas port in the gas cylinder . Right?
So , once you perfectly align those 2 above using the "free" shims , then you will get to install the factory gas lock . What are you going to do if the gas lock starts to tighten at 11 oclock ? Lets say you supposedly turn it backwards and it tightens at 7 oclock. If you add or remove "free" shims , you risk throwing the gas ports of the barrel and gas cylinder out of allignment . Now what ???? What are going to do ???? As suggested in a post here , you can stone ( grind _) the gas lock , but what if you dont have the tools ?
Here comes the adjustable gas lock to help you out .

Ok . I am not trying to pick up fights , but let me tell you that this device is a lot more than a replacement for "free" shims .

I will tell you what I know about it , as I was waiting since few years ago for Dlask to move his ass and finally make this one .

The first prototypes were given for testing to 3 different guys who are fairly experienced with the Norc M14 . They didn't know each other , so they worked independently .
Although all three were using this adjustable gas lock for the first time and they didn't know from each other, all of them went instinctively to look for the optimum torque of the nut , trying different torques and looking to find a sweet spot where the barrel would respond with better accuracy . Two of these guys were using a factory load and the third was looking for a torque to give accurate results with 2 different loads , probably different bullet weight .

If you ask me , it's a neat idea if you like experimenting .
It has nothing to do with unitizing , as it works with or without unitizing .

I didn't use this yet , as I am out of the country most of the time , but once I will have time, I will get one and try experimenting.

CGN member Lector came with this idea of adjustable gas lock long time ago and he gave it to Dlask , who slept on it for few years . I wish Joe Dlask would pay more attention to the designs Lector gives him .
 
Hey, I wasn't knocking it as a product at all. It's actually a very clever, well thought out solution to the twin problems of timeing your gas port and gas lock as well as a means of using your factory front sight on a chopped barrel. Just not the 1st upgrade I'd spend my money on
 
First of all the shorties from CanAm will have the front post sight near the gas assembely but in its traditional space on the flash hidder itself.
This product on the other hand is made for people who chop mod there regular length berrel. As it doesn't make much sense running 2 front sights.
Here is what we are going to be seeing preaty soon:

Now if Dlask caugh... caugh... ;) ;) was to make a muzzle deviece to thread on to the chinese threads sort of like SEI's vortex for USGI barrels this gas lock would be a great addition to anyones "Made In China" rifle.
 
Hey Satain,

The flashhider and front sight are one piece on the Canam m305's right? They are threaded to take any USGI threaded muzzle device?

They use a castle nut and gruves for the flash hidder to slide on for proper alignment. The gruves on the chinesse barrel are different than the 1's on a USGI. Hence you keep the castle nut and replace the flash hidder or muzzle brake made for the M14 platform and bobs ur uncle it works not matter were it's made because the castle nut is the one that retains it to the barrel.

So if it was a builders intention to run with a different model of flash hider and would benefit from relocating the front sight to the gas lock, this may be a good way to go then?

Kind of makes me wish Lector and Joseph came up with a ringed front sight version... kind of similiar to a Navy-type sight version I noticed while browsing;

It still may be a decent idea if one were to go with a chassis system like a Troy or an EBR?

Perhaps there is a dovetail hooded front sight availble? I'm not convinced the hooded type is better or worse, but I do prefer the sight picture... for me anyway.

If thatz what you like than go for it & don't let anyone tell ya different. Some people like wood & some people like poly & yet some like fiberglass. It's all about you when it comes to ones rifle.
So since you want a front hooded sight on a flash hider and wether you use this Dlask 1 or the front sight mount on the flash hidder. I believe this is what you would want to look for;

Having shimmed M14's since 1967 I have NEVER had one that ended up with misaligned gas ports with proper gas lock nut tension no matter how many shims had to be used.
Joe's new device is not an expensive replacement to cheap shims.

However - It IS extremely useful for a quick field adjust. If shimmed finger tight at 4 o'clock and tool tight at 6 the rifle shoots one way, if 4:30 and 6:30 it shoots differently.

With this new device you can instantly adjust for tighter cold barrel groups (more hot barrel POI wander) - great for 1000 yd shoots, or -

Slightly larger cold barrel groups (less hot barrel POI wander) - great for matches with high quick round counts.

WITHOUT ADDING OR REMOVING SHIMS !

Brilliant - me wants !

I was just wondering I had a 2009poly chopped and after that my front sight was too short ,I was wondering if the new sights on the factory shorty will be taller?or was my front sight being too short just a fluke.

It may not have been answered as it was completely off topic;)... there is a special level of hell just under the pedophiles and lawyers reserved for threadjackers:p

However, that said, until they arrive it's unsure, but based on pics they appear to be the same as the longer barrelled counterparts. A decent smith should be able to raise it for you I'd think though?
 
Thanks chopper 1. Until your post it still seemed clear as mud to me as to the benefit of this new device over shims.
