This is my first post in about 3 years. The last time I was even on the site was before this current format.

The SLR-106FR from this test has been sold on to an acquaintance. He was willing to spend the money on the new ejector and refinish that welding would require (the old-style squid ink Arsenal finish was completely toast long before anyway). The barrel was basically shot out. I honestly can't remember the throat gauge readings (or the exact round count) anymore, but I remember it being really visible. The barrel also had crown wear. It was shooting 6 MOA. Total round count was in excess of 40,000 rounds. The overwhleming majority was South African surplus M193 5.56mm, probably 30,000+ rounds. Some Federal/LC M855 (a few thousand rounds), some Hornady TAP training ammo (1,500? maybe).

The ejector failure wasn't the result of the welds popping, the tab itself broke off. The rifle was still somewhat functional, with poor, erratic ejection, and the occasional stovepipe. I didn't actually realize what the cause of the failure was until I found the piece of the ejector in the receiver under hammer pin.

Thanks for the update and the correction Redmanfms.

It seems to have been lost in the forum update, but I feel it's important to add what I can recollect of the info here:

Redmanfms commented that his rifle went into 39k-40k or so and finally quit when the anvil head on the ejector swelled large enough to be caught by the bolt, ripping the ejector loose from it's welds. He mentioned considering having it welded, but not really wanting to deal with the hassle. He mentioned at that round count that accuracy had started to decline. I think the number he used was 5 MOA or so.

I'd like to further add that my own experience with round count in my SLR-106 ended recently at between 6000 and 7000 rounds of mixed Wolf and Brown Bear .223. My rifle originally shot around 2 MOA with Prvi Partizan 75gr match and now shoots 6+ MOA with the same.

Lesson learned: bi-metal jacketed ammo wears barrels (even cold-hammer-forged, chrome-lined barrels) about 6 times faster than copper jacketed ammo. Keep it out of firearms that don't have easy-to-replace/cheap barrels!

Update and extractor spring info?

I know the carrier interchanges with a standard AKM carrier. I swapped out with a buddy's WASR 10 carrier and it ran fine. I checked it carefully before firing, of course. The shape of the cam channels in the carriers are identical.

ETA: The bolt carriers are NOT identical. There is a relief cut made for the left magazine feedlip on the SLR 106 carrier. Otherwise, AKM carriers are compatible.

Thanks for the update Redman. Good info.

It's really great reading these round count reports on the 106. Thanks for sharing the information.

I'd be very curious to know how the barrel holds up from this point on.
