L4 mag issues

[AmEngRifles]

Thanks Joe. I had started down that path you had suggested. I got the springs to go around the recoil rod, but never could make a satisfactory block to keep it from going through the striker. I may readdress that, but never understood the part about taking up space with the recoil spring inside the butt? Seems like nothing inside the receiver has any effect on the recoil compression inside the butt?? Am I not seeing something there? I never got to the point were I fired the thing, mostly because of the striker "plug" issues.

Now that I have an extra Project Guns striker laying around, it may work with your upgrade? Have to check firing pin protrusion to see?

Thanks for refreshing your approach to the issue.

One other thing that MIGHT work is to go ahead and get another ML striker system (he makes them in batches and may not have any at the moment?) and just file away the left side guide rail on the ML striker. Between his striker guide rod and the right side guide rail, I don't think the striker would bind? ML made me two firing pins as well, one in HA length and one in PG length. I may find some combination of striker and spring other than the HA system that works in the L4?

I should't have to be working this hard on a rifle that cost well over 5k. Having semi auto Bren's should be for builders only. I compare this to a buddy who used to own a Porsche, then sold it. Said it was fun to drive when it was running well, but it spent a lot of time in the shop getting tweaked.

Joe, thanks for the Link. I am on there, but only as a browser, since I am not a builder. I tried to find a local machinist, and Tony was suggested. Found his web site, dropped him an e-mail. Never got a response. I will keep searching for the right answer and combination. If I can get the left side rail pathway milled out, say for the length JUST enough to allow the striker it's travel, I would do that, but yet to find a machinist in my area. I think Mad Dog Machinist is in Macon, but have yet to attempt to connect with him. But, if I get it milled, I will upgrade to the ML system in this L4 as well.

AER,

When you introduce the striker into the recoiling parts behind the bolt the full compression of recoil springs is less than the full design compression by the length of the striker. The bolt travel is less than design by the length of the striker. Since the return rod bears on the bolt, the springs cannot be fully compressed. The addition of a plug ,the length of the striker, behind the roil springs assures full design compression of the recoil springs with the striker in place. Hope this explains it.

Thanks Joe. Now I get it. Appreciate that. Thanks for hanging in there with me.

My email is: csmarcher@socal.rr.com
And I have a half dozen striker springs so you’re welcome to one to modify as needed. As far as the gas regulator try it, if it works pick up a spare and modify it as per mine and drop mine back in the post when you’re done with it.
Offer stands as before 👍🏻

Thank you Gary, I will do that. Let me touch bases with you next week. Ending out a busy week, with heavy storms tonight headed our way. Hopefully my week ends on a good note. Will be decompressing this weekend.
