I just got off the phone with Ron Smith at Smith Enterprsies and he said he will do a run of Dovetailed Gas Lock Front Sight Bases with metric threads for us if there is enough interest. This base would allow the use of USGI M-14 front sights or the Tritium front sights sold by Smith Ent.

The question is do we want them for short or standard barrel lengths?

Please don't vote in the poll if you're not serious about purchasing one. Price will be about $75 US

So the advantage to this over the marstar/HK style gas lock sight is that you can mount the normal front sight instead more windage adjustment etc?And why is there a difference needed in barrel length.I though the only reason to get the gas lock front sight was because of a shortened barrel.Still learning the ways of the M14S.Later
 
I agree that most people will want the dovetailed base as a result of cutting their barrel, however we need to present Ron Smith with some numbers before he makes anything. To his eyes, no Metric threaded guns were ever made in 18". We need to show him how many of us up here have (or will...) cut down our barrels .

The difference between the short base and standard is the hieght of the base. That way you can still use the range elevation in your rear sight.

Besides giving you windage, a dovetail front sight base will allow you to use national match sights, tritium ect.
 
I spoke to him at the shot show on Saturday. He said he is extremely busy with the war. I think the only way to get them is to order at least 100 of them. I will take 2. Anbody out there take the other 98?

I went through this intellectual exercise once. The height (plse correct me someone if I am misremembering this) is lower for the 18" b/c the ballistics of the bullet is different, i.e it's slower out of the 18" barrel so your starting aiming point for 100m has to be a little higher. The front sight is lower, so you have to elevate the barrrel a little more.

Make sense?
 
marstar has the metric threaded , hooded style standard gas lock sight... in steel and in titanium. I've installed one on someone elses rifle and he is very pleased with it. I have one currently on order :D
 
PS: I don't really like the GRFS, and especially dislike the HK style post and aperature/ring of the NAVY style GRFS, but I've used a few of them on my shorties. The GRFS that uses the original GI ft sight is a major improvement, IMHO.

That being said, I have designed a different front sight for the M-14 shorties that clamps on around the barrel [ like an AR 15 split gas block with two screws ]. The drawings [ and the napkins the drawings are on ] are with Joe D to make up some prototypes. These would be a lot like the Ruger AC 556 front sights.

Next time I'm over at Joe's shop, I'll remind him.

If there is enough demand to make up a CAD program, we might actually see these in production some day.

A CAD Drawing (or "blueprint" as they are sometimes referred to) or a CAM program in like MasterCAM ?? :confused:

I've been looking at the GLFS, cause I'm considering of spending alittle one on one time with a lathe and mill to make a NATO Rifle Grenade/Muzzle Break for the M1A. Still just need to know the outer diameter of the Castle nut and I'm ready to go to get a nice looking CAD drawing of it to work from. :)

Can you tell I've got too much time on my hands waiting for my M1A that I'm starting to think of things to do to it before I get it. :redface:

Ron said he'd make them if he got 50 orders. Once again this is the dovetaled base that uses the original front sight. I've had bad luck with the HK style sight.

If you're serious send me a PM with an email address and I'll send that to Ron. Hopefully he'll take that as sufficiently interested to make a run and then email us all when they're done.

Put GLFS in the subject line and state how many you want. Cheers.

The one problem with this sight from Marstar is that the outline is a little bigger in spots than the standard gaslock, so the gaslock wrench I have from Brownells doesn't fit! :mad:
 
IMHO, the Gas lock Dovetail sight base is the way to go.

I had one on my SAGE/DMR M14 with a Tritium front sight.It was the sh*t!!!!!:D

I found the regular HK style GLFS great on the M14 shorties.I opened up the rear sight aperture for quicker target aquisition.

The reason that the sight bases are different heights has nothing to do with barrel velocity, it is all about sight radius.....or would parallax be a better way to put it. See pictures below, the difference is barely noticeable but after a few hundred metres that is a huge difference.

L-R Regular Navy sight, short barrel, long barrel
The regular navy sight has an adjustable pin in it for adjusting to your own barrel length.....most people that have them don't know this

If you use a regular base on a short barrel you can't get your rear sight lower than about 250 m if I remember, if you use a short barreled base on a long barrel your rear sight won't get out past 700 m or something like that, my brain is a little rusty at the moment. Does that make sense to you guys.


Ron has told me many times over the last 6 years he would do the metric thing, but when the time comes he is always too busy.
If you do manage to get him to do an order, I'm sure if you can get 50 together he would do 25 of each as the blanks are all the same until he taps them.......so it should be no big deal what heights you want.

Glad to hear that.
Sometimes I can't quite get the right words out of my brain.
I'm stuck in bed today with a bad lower back so I have some time .....for the time in a long time to hang out on CGN. ;)

Although I'd rather be surfing :p
