Norlock washers are an option, too, so long as you've got a rod to check concentricity.

And a strap wrench to take your suppressor off.

Had an issue with mine last week also on my belt bed after about 1k rounds. It was really weird, it locked up. Hammer wouldn’t fall. Trigger was locked. Kept playing with it and somehow freed itself and started working again.

Didn’t fire it again cause I was dark and scared it wasn’t actually fixed. Wanted to look at it more closely once i got home. Seems good to go

I forgot to mention that. Selector was locked to binary and couldn’t move at all. I’ll be going back up north to test it out again next weekend and report back.

I had the little nub that holds the floating sear lever break off on a Gen 1 trigger pack.

Sent it back to Fostec and they welded/soldered it back on.

Runs great as a recreational range toy.

These were stolen from the old Fostech thread. Their parts are too "soft", for lack of a better way to put it, and they're prone to stress fracturing from the metal casting process.

Hell, people are receiving them with chipped sears.

-----------------------------

I think this could have been a massively successful product....at twice the quality and half the price. Nobody wants to buy a mil-spec feeling trigger that breaks in a couple thousand rounds and the appearance isn't particularly confidence inspiring - especially not at $500.

If at $300 even they were made to the quality of a G/Larue trigger, they literally couldn't make them as fast as they sold.

I own both and have had WAY less problems with the Fostech. The FA trigger runs into a lot of issues with outrunning the binary. Never had that happen with the Echo. My hammer does have some noticeable dents in it though, and I have thought a number of times how I wish at least that particular part was a bit better. But I've put 6 or 7k through it with no failures, so no real issues.

From what I recall, most or all of the broken parts from the Fostech thread here were from pistol caliber rifles. So as mentioned earlier in the thread, i'm pretty sure that plays a big role.

If your rear cap has any small holes you could replicate something like this mac11 suppressor collar for the gemtec viper


I have been toying with making a similar collar from a flat band of stainless and a single tension screw to draw it tight on the barrel. Then it would have a small pin that interfaces with the rear of the can to prevent it from rotating loose. I have had issues with direct threads coming loose over a long course of fire on a precision rifle :/ accuracy goes to hell but luckily I never had a baffle strike.

That was my initial thought as well - but I didn't want to say it because I thought that would be retarded, literally nobody would try and do that for viable gun parts

It looks like I'm not the only one with those inklings.

It's a real shame. The Fostech is the superior design (to the Franklin) because of the back up disconnector. The problem that it has is that it's just made like shit.

I understand why they would do it that way, but sintered printed material is not strong enough to put up with the impact. There is a newer 3d laser printer that doesn't need the sintering process. Which would be golden for this application. It can even do Inconel.

To do it proper, leave the housing in printed form, but have all the internals laser/waterjet cut out of tool steel. That would get them the best of both worlds.

Does this happen with 5.56 as much as 9mm ARs?  Seems like 9mm's have had more rep of beating up parts than 5.56.

I love my Fostech trigger in 5.56 - I'd hate to have it end up like that!  They are not cheap.

Well I don't know exactly how man rounds but it was the same trigger I was having problems left with last time. Except this time didn't have a single hang up besides failure to feed due to links being too tight. I dont get it. Not that I want it to fail but it was like a whole new trigger compared to last time.

I'll take more pictures tomorrow but this is all I have for right now. I shot this plus another (2) 250.? round pouches.

Use the HATE ring and a ASR module with their 9mm single chamber brake. You won’t have that problem again.

Yes Gibbs upper, SLR rail and QC10 BCG.

I am using a Franklin Armory binary, and have at least 2k through it. So far it doesn’t look anything like these pics of the fostech. The system can out run itself,  but once the cadence is learned you can mag dump. I experimented with diffetent buffer weights and springs, and the BAD Industures PDW stock uses its own buffer and spring system. It has worked the best.
