I had problems with light strikes every few rounds that I fought for a while. The problem turned out to be the charging handle not staying put. During fire it would bounce off the ratchet plate and would return from the bolt hitting it. This happens so fast I couldn’t see it till we caught it on vid...

Does anyone know where to find a mg42 twin mount? I have been looking the web up and down. If i don't find one soon i will end up building one so if anyone has good photos that would help. I'm open to ideas on building one.

I got my kit yesterday. What I difference the Recuperator has made. I have not shot it yet but it does the pogo test (with the bolt back like it should be) much better. As a side note my kit from apex was in really good shape. The front half of the gun has the cam section intact. I think I will just...

I got the kit because I'm building a second one. Is there a good source for the springs? I have no problem rebuilding both of them.

Just got done looking over H. Dv. 181/7. Looks like I have been doing the pogo test wrong. I have always done it with the bolt forward. Looks like I should be doing it with the bolt to the rear. In this case my gun fails the pogo test. I have a m53 parts kit on the way so we will see how the spring ...

I get 19.5" from the rear of the stop under the sight to the very end of the bushing (using a tape measure) too. Today I re-measured everything. Looks like my bearing is 47.67mm or 1.877” it will stick out the bushing 13.19mm to 13.37mm and sink in 7.32mm to 7.61mm depending on what point along the ...

This is fantastic info. I will try to measure tonight when I get home.

As far as the overall length. This receiver was once a semi auto build by wise-lite. The thing did not work . So my receiver is about an inch longer than it should be. What I did is I made a spacer about an inch long that goes behind the recoil spring and the buffer was extended by wise-lite when it...

here is what little video I got. https://www.youtube.com/watch?v=OmWTofvvNdI

Next time I will try to do a better job on the video.

I did use the m53 Recouperator. It seems fine I can compress it all the way and it’s smooth. The gun will pass the pogo test. The bolt assembly is made up of m53 parts but has an mg3 bolt head. Before I used the mg3 bolt head it had the m53 bolt head but did not seem to make any difference. For this...

ok my mg3 nozzle/booster is 10mm. I also have a 10mm booster I use on 7.62x51 with the 2 piece booster/nozzle. I use a 11.5mm booster I use on 8mm ammo with the 2 piece booster/nozzle.

yes I have given the length of my BARREL-BEARING's 47mm or 1.85" and 49mm or 1.93" I used the 47mm on the first test. This is the one that sticks out about 13.3mm. On the second test I used the 49mm. This one sticks out about 15.3mm. On the booster I used the mg3 one piece nozzle/booster for 7.62x51...

I just realized I put rps not rpm. I also put bushing where maybe I meant to put bearing. I wanted to refer to the piece that the barrel locks in to and not the piece that welds in. From this point on I call the piece that welds to the receiver the bushing With the barrel bearings I have 4 of them 2...

Finally made a big improvement. I was playing with it the other day and saw that the bolt unlocked before the barrel bushing got to the vents at the back of the booster. My thought on this is if the booster was placed forward more the vents on the booster would be open more. Allowing more gas to ble...

Thanks Blanksguy. I want to first make sure we are both clear on what I meant. Shooting brass 7.62x51 or brass 308 I have never once had a problem. Shooting the steel 308 tula ammo in a 7.62x51 headspace I would have case head separation every single round. At least the 3 or 4 times I tried it. It a...

Thanks. I do use proper headspace gauges for both 308 and 7.62x51. When shooting the tula 308 I use a bolt and barrel that headspace for 308. I checked it before and after. I can buy in too the unlocking too early. I'm putting together a 1919 so maybe I will just save the ammo for that.

Are you guys telling me my gun is blowing parts and cases because I have bi metal jackets? Also how many other countries are using bi metal jackets in their guns? What do most people shoot in there ak47? Most my surplus ammo made to be used at war is bi metal. I’m not arguing with you guys I’m sure ...

Well I have decided to give up on trying to get tula 308 to run. I have a FA m53 converted to 308. I have found that my old bolt will headspace for 7.62 and my new mg3 bolt will headspace for 308. The tula 308 will not run at all in 7.62 headspace as the back of the case comes off every round. This ...

Is the top popping open normal?

Thanks John. I at least owe you lunch for all your help. I found that unscrewing the flash hider half a turn did not make any difference as john knew. However I did look threw my parts and found another Striker Sleeve that was smaller than the one in my bolt. After swapping my problem went away. I w...
