As of right now i have a front sight via the stock m1a flash hider/front sight but next week my aac blackout flash hider threaded for .595x32 for my 762 sd will be here and when i put it on i will have no front sight. I tried to install the S.E.I. Dovetail gas block for 18" barrels on here and i just could not get it to index correctly. When the crush washer with proper size S.E.I shims were used, the gas port from the barrel all the way through the gas cylinder line up perfect but the S.E.I dove tail block has to be wrenched on hard which eventually pushes the gas ports out of align, not to mention i bent the fulton armory gas block wrench. I went back to the factory block and all went on with ease.

Im going to discard the crush washer and order more shims and try using only shims. Anyone who has knowledge on this help me out.
I was considering the hooded smith GLFS but am leery of anything seeing as to how difficult it was to put the last one on. My EBR is below and is finally in working condition.

SS=Scout Sniper not NAZI

SA SCOUT/SQUAD 18" BARREL
SAGE MOD 1 STOCK
SOON TO HAVE STRIPPER CLIP BASE FROM SAGE WITH A MK4 M2 LRT
Thanks
Mike

Re: EBR Mod 1 complication HELP

Did you mark up the SEI GLFS dovetail? If so sell it and buy another. If not, exchange it. The threads will likely index differently.

If you really want to make that one work you can try to relieve some of the metal from the back using fine grit sand paper or lapping compound on a flat surface (glass, granite or marble sheet). Make figure 8's applying even pressure till it indexes correctly. Now, the downside to doing this is you change the dwell time which can screw with the accuracy. So most prefer this to be a last ditch option.


How far off is the gas port with the lock backed off to the next alignment location or the shims removed to allow it to be snug by the 4:30 or 5:00 o'clock position and then wrench to 6:00 o'clock? As long as a 1/16" allen wrench passes through the port into the barrel you have good alignment. The hole in the gas cylinder does not need to be "perfectly" aligned and is drilled larger to allow for it to be either forward or aft of center and still allow gas to pass through.

You could fit a dummy selector or lock kit to fill the selector holes. May take some careful work working with aluminum rather than wood or fiberglass but I've seen it done.

And if it means "Scout Sniper" why did you use the Nazi Schutzstaffel type lettering rather than say the Chevy Super Sport type lettering? Do you plan to explain that to everyone you see at the range who thinks you're some antisemitic gun nut?

Re: EBR Mod 1 complication HELP

It sounds like you really have a aac blackout flash hider 762 sd complication.
I have installed and swapped out many SEI GLFS and have never experienced a problem.
The crush washer did give me problems with alignment and timing,
these problems were solved by replacing the cr with shims from SEI.

Also, don't use the crush washer and shims together.

Have you tried a different gas cylinder?

I wish I had your rifle in front of me...

Its completely marked up but luckily brownells.com has a 100% return policy and i can get my money back. I ordered a new one from smith along with another set of shims and im going to try that. Ill try the allen wrench trick too, i was not aware the holes did not need to be perfectly alligned.

As for the SS i didnt choose the symbol, the USMC 2nd Mar Div Scout Sniper School did and this has been the insignia used ever since. I simply chose to put it on my rifle just like we did when we were in. I don't plan on explaining it to anyone because i could care less what they think unless they are a jew or something. I only explained it in this forum so a heated discussion would not begin on the topic. Im the extreme opposite of racist and that is good enough for me. To many blood sweat and tears along with my mental state was put into the whole sniper job when i was in for me to care where the SS was originated.

I truly appreciate your help with the rifle i am definitely in a rough place with this build. Im sorry if i have offended anyone it is not my intention.

I wish i had my rifle in front of you as well, from what i hear, you are the man to go to. I have not tried a new gas cylinder it will be the next step if the shims only (no crush washer) and the new GLFS-18 does not work.

I have no problem with the AAC Components. My scout squad has an 18" barrel and allows enough standoff for the can and the flash hider.

What it comes down to is the fact that the day i received the M14, was the first time i had ever touched one. I had the rifle in my possession for less than an hour before it was completely dissassembled and was being dropped into a sage. My over torque on the initial GLFS with the shims and crush washer may have been the root of my problem. I also fired 20 rnds through it with the gas system indexed improperly which caused failures to feed and extract and some jammed rnds in the chamber. luckily no damage to the gas piston was done. The factory gas block is on and i havnt had a malfunction yet. I put about 100 rnds through it on sunday. Any tips let me know thanks.

a new GLFS and shims are on the way

I checked the alignment of the gas system withba flashlight and it appears that the holes are aligned perfectly this is most likely due to the fact I used a punch that filled the holes entirely so there was no misalignment. now that I know I can use a 1/16 I will have some room for adjustment. regardless I am waiting for the new glfs to arrive with shims and I will attempt it again.

Re: EBR Mod 1 complication HELP

Let us know how the new parts work out. I don't have an EBR chassis but my gas system is all SEI (cylinder, piston, plug, GLFS dovetail 18") and it all locked up perfect with no shims needed as well as having the proper dwell on the piston. I'm sure I lucked out there but I'm very happy with the setup.

Re: EBR Mod 1 complication HELP

I scrapped the crush washer and used a full set of smith shims plus two of the smallest shims from another smith pack of shims. the new gulfs locks up real nice, hand tightened just like the factory. piston moves freely and my on off gas spindle moves with just my hand.got the aac blackout fh on and everything lined up beautifully. test fire it tomorrow thanks
