**Updated title and text**
Hi everybody
I am posting today because I am looking for some help from the community or from someone at IRG, if they have seen such issue before. I bought a PSA 7.62x39 10.5 complete upper, with BCG from IRG and I am having some issues with it: it gives me FTE (Fail To Eject) issues in a very inconsistent manner. It can be once every 5 rounds, can be OK for 15-20 rounds and then fail 2-3 rounds in a row.
The symptoms are that the spent shell casing exits the chamber completely (no Fail To Extract), but not the upper receiver and does not exit by the ejection port. It does not ends in a stovepipe: it just get rammed back with a new round from the mag and jams the weapon because a double feed.
I have tried running a heavier buffer (H2) with same result. I also replaced the original (PSA) extractor spring with a much stiffer Wolff one: same result. Bolt and rifle was completely cleaned and I run it well oiled with CLP.
Doing a dry cycling of the rifle will not replicate the problem: rounds will eject properly each time.
I did some tests today : I tried several different mags (XCR-L pistol from Questar) with several different loadout (1-2-3.. rounds) : no difference. I also tried brass American Eagle ammo versus Barnaul steel case : no change.
Last test I did was to load a round, then drop the mag and fire: sometimes the empty shell case would get re-loaded in the chamber!! If I tried the same thing, but kept the empty mag inserted (last round in chamber type of thing), the BCG would remain in the back and the empty case would just sit in the upper receiver, over the mag ...
I am suspecting a problem from the extractor and/or the ejector but any input would be appreciated.
