Mine required no fitting. The parts (including the disconnector if you want to change that to Bulgarian as well) drop right in and everything functions safely.

You can get Bulgarian FCGs from here for very cheap:: http://www.clearviewinvest.com/bulga...connector.aspx

The ones from Clearview look slightly different than the ones from K-Var and I think that’s because they are surplus rather than new production. They are beautifully machined as well, moreso than the ones from K-Var. Both the K-Var FCG parts and those from Clearview required no fitting.

One warning though, if you change out the trigger itself to the one from Clearview, rather than just the hammer and/or disconnector, you will notice a tiny bit of grittiness.

The carrier tail deformation I saw in this thread seemed completely normal but that’s not my concern. I just hate the weakest link in the rifle being a crappy cast part. Imagine the hammer breaking when you need the rifle for defense.

I picked some up from Clearview and some from kvar. History has shown me that anytime I need something and wait because it's plentiful it usually doesn't stay that way

OP, my carrier tail looked pretty similar after 2 or 300 rounds. I actually sent it back to arsenal and they replaced the carrier. The new carrier tail looks almost untouched after about another 1200 rounds. With shipping it there and getting it back, it was gone for about 2 months FWIW.

I have not had a chance to take my rifle part and look at the hammer. If I remember correctly some of these rifles came with Bulgarian fcg parts and others us. The same goes for the furniture. Is my memory serving me correct or did he's all have us made hammers?

I noticed the tail of my disconnector is also rubbing into the pistol grip rivet. It's completely scraped the paint off the rivet, so I ordered some spare disconnectors as well. Anybody else having this issue?

Doubt it's a problem. Some have filed those a little.

Dunno on your particular Arsenal/model. Arsenal uses a specific large cheesehead type rivet on the rear trigger guard rivet as a disconnector rebound stop or some such. IIRC.

makes sense to me.

This thread is very informative. I'm thinking about buying a Sam7r since it seems like they're gonna be gone for awhile soon.

Yeah I did this same thing with the FM vepr's. I put it off and put it off then boom, they jumped to like $1500 and now you can't hardly find one anywhere.

There's one in the MP for 1150 shipped. In great condition. Unfired. Has some extra stuff added also.

Hey everyone, I found this thread very helpful thank you. I am relatively new to AKs but not guns, I have a sam7r and followed this threads advice to switch out my hammer from the LV factory and attempted to put in the Bulgarian one linked earlier in this thread from Kvar. I found that with this installed, my bolt carrier couldn't slide forward. The top of the hammer was too rounded and didn't allow the bolt to slide on top of it. Ive looked into polishing hammers but this would require more material removal than I'd like. Any advice would be appreciated. Thanks.

The ones from Clearview look slightly different than the ones from K-Var and I think that’s because they are surplus rather than new production. They are beautifully machined as well, moreso than the ones from K-Var. Both the K-Var FCG parts and those from Clearview required no fitting.

That's odd. I added Bulgarian hammers to 3 of my SAMs (two from K-Var and one from Clearview) with no issues. I did have the issue you encountered by trying to install unidentified European FCGs in my other AKs (the bolt carrier couldn't slide forward), but not with the Bulgarian hammers in my SAMs. I didn't have to modify anything so I wouldn't be able to give you advice on how to do anything like that. The bolt carriers slide over the Bulgarian hammers smooth with no issues at all in my rifles.

Man that's a bummer. I plan on making that swap on my two sams in a couple weeks when the schedule calms down. Would be interesting if one of those hammers would work with a few of my atlantic builds that use the tapco fcg

Did you test with the bolt in the carrier before testing? If not, try racking the carrier with the bolt in the carrier.

^^Yeah, was about to say the only time I've had that issue with any AK is when I forget to put the bolt in the carrier (usually when fitting carrier to rails building on blanks, but I'll admit that it's happened when reassembling after cleaning once or twice lol). No reason the bolt/carrier shouldn't be able to ride over the hammer if it's being held by the trigger hooks.

Cut/ grind off one of the hooks on a double hook. Can also work as an over travel trigger stop.

Hey Blue, will FA bulgarian hammers work on a semi auto gun? I guess I may replace the hammers.

My carrier tail looks the exact same as Rockytop1911's. About 750 rds threw mine. Did the exact same thing, mushroomed a bit then stopped . This is a sam7r-66 ser# in the 11xx range

So these will fit the milled Sam7?
http://www.clearviewinvest.com/bulga...connector.aspx

Does it matter to have specific “milled receiver” parts like the one kvar is selling?
https://www.k-var.com/hammer-for-mil...nal-bulgaria-2
Would an AKM hammer like this work fine?
https://www.apexgunparts.com/rifles/...very-good.html
I just want to reduce further mushrooming of my Sam7.

Yes it matters to have milled receiver specific parts. They're referred to as double hook FCG parts and you need double hook parts for a milled receiver. I'm honestly not sure if a single hook hammer (AKM) would work and I personally wouldn't risk it.

Sorry for the late reply everyone. One thing I noticed is that with the bolt carrier racked backwards is that the hammer isn't actually being held in place by the trigger hooks. Everything is in place correctly but it doesn't want to sit into those hooks. If I were able to have the hammer secured by the trigger hooks it would have enough clearance to rack forward with the Bulgarian hammer I bought from Kvar. I feel like there's something I'm overlooking. I'll look into it more this weekend.

I feel like an idiot asking, but is there any issue with buying the stamped receiver Russian hammer from K-Var for an SLR-104FR? I can't imagine there would be but I'll await the experts!

There could be issues. I do know that the Russian hammer used in the Vepr FCGs has a very unique geometry. There's more steel on one of the "tabs" where the trigger hook slips off. I don't know if this is the same hammer though. Either way, mixing FCG parts sometimes works and it sometimes doesn't.

Thanks for the quick reply. I'll avoid it then. I didn't see a stamped receiver Bulgy hammer on K-Var, which is why I asked.

Those are Saiga hammers.

They can be used with AK74 triggers and disconnectors.

The 223 version is unique and designed to be used with the 223 Saiga bolt.

The 7.62x39 and 5.45 versions are normal AK74 profile.

In a milled receiver, the AK74 trigger may need to be modified to rotate far enough forward to function.

The Bulgarian milled receiver trigger and hammer parts would be a better match in a milled receiver.

Thank you. So if you were a betting man, would it be okay for me to purchase only the saiga hammer for use with existing Arsenal USA disconnector? I am looking to use it on my stamped Bulgy 74. Also going to buy a milled Bulgy version for my SAM7R.

Tldr; Do I need to purchase new discos to go with the new hammers for each rifle?
