I'm sure everyone is good and ready for the 7.62 conversion and I don't blame you. I've had the opportunity to shoot it a couple of times and folks it's well worth the wait. I had to photograph the gun for a publication so I needed to get a kit early. After shooting it (pics) I shot it (bullets). Here you go.

The kit comes with a new (bigger) brass deflector, barrel, bolt, and heavier hammer. It comes with a trigger spring as well. I installed all the new goodies and headed to the range. In my bag I had Wolf (in the black box), Barnaul, some 7.62 in a white box (Russian made), and Golden Tiger 7.62x39. I've had all the ammo for a while now but the Golden Tiger I recently bought because of something I read on this forum.

I loaded up the Cproducts mag and I was surprised at how easy it was to load. Nice and smooth with positive clicks when I placed rounds in the top. I loaded it to 30 rounds and only the last two rounds were a bit tough to get in. I started out with the Golden Tiger and fired a few rounds. First thing to note is how much harder the 7.62 shoots than the 5.56. I remembered what Terra had said about running a couple of mags and they would work smoothly. After about 8 rounds I heard a click and nothing happened I cleared the round from the gun and assumed it was the mag. Upon examination of the round you could see that that primer was hit very positively. A nice deep strike but it failed to go off. I replaced the magazine and proceeded to shoot again. After 3 or so rounds the same happened again. A "click" but nothing happened. This round looked the same as before. I think I had about 4 or 5 of these in the first mag. I then loaded more Golden tiger and every 4 rounds or so a round wouldn't fire. I went through roughly 45 rounds of Golden Tiger then decided to switch ammo. I pulled out the Barnaul and fired of 20 rounds with no issue. Then I loaded the white box Russian stuff. Twenty rounds no issues and I noted that this stuff was much hotter than the others. I believe I had the gas system on 2 at this point and cases were landing about 12-15 feet away.

Next I loaded the Wolf. Twenty rounds and I had one of the primer strikes with no ignition. I won't call them light strikes because they were in no way "light". These strikes were deep. They were so deep I couldn't figure out why they weren't igniting. I then went back to the Golden Tiger and had more of the same. Solid hits on the primer, nice and deep but several didn't fire.

The magazine was flawless and smooth. I fired rounds while holding the mag and moving it around to see if I could get it to feed wrong, but that didn't happen. It ran tip-top from the start. People say 7.62 mags are not reliable and I can't speak for previous models. I can tell you this one runs as it should with no hang up of any sort. Load 30 and shoot. Simple as that.

I called Alex and told him about my outing. I told him everything went well except for this Golden Tiger stuff. Alex has never even heard of the stuff. I explained that I read it was a good choice as opposed to Wolf Classic. I told him the strikes were really deep and he told me that maybe the primers on the GT ammo were bad or just too hard. Looking at them, I had to agree. I asked him if he thought a heavier trigger spring might help and he said maybe it would.

I went to my gun shop and told my buddy about the issue and showed him the rounds that failed to fire. He couldn't believe they didn't fire when he saw them. I asked for a heavier spring and he grabbed some old thing he had laying around that came out of an AR15. I don't know what kind it is, but when I compared it to the one in the gun it felt noticeably heavier.

I went back to the range Thursday with the heavier spring and fired 100 rounds of the GT without issue. No hiccups. I'd dump a mag, reload and shoot. I loved it. The Robinson is made to shoot that 7.62. After that I sent Alex an update on the matter. He was pleased. He said he will be ordering some of the GT ammo for testing. They have a new match hammer they are working on and maybe that will make the difference on the GT stuff.

I did run the gas on setting #1. The cases ejected and landed about 8 feet away. I ran a couple of mags like this and found it to function properly while cutting down on the obvious recoil of the 7.62 cartridge. I only shot at 25 yrds. I used the Eotech already set up on my gun. I was shooting 2-3 bursts and it seemed to shoot pretty accurately but I did no slow fire testing as I wouldn't use it for this application.

So at this time I'd steer clear of the GT ammo until their (Robinson) testing is complete. Unless you want to put a heavier spring in the trigger. I must also note that after I put in the heavier spring I ran that 2 day carbine class with my 5.56 kit. I thought the heavier spring might mean I'd have to change the gas setting because of the extra tension on the action. Well, that wasn't the case. I ran two days around 800 rounds and beating the crap out of the thing and never one malfunction. This gun rocks.

You'll love the 7.62 kit.

Here is a pic after firing the GT ammo with heavier spring. I took this with my iphone so the quality isn't that great.

I pray to god we have reasonably priced non corrosive ammuntion in Canada by the time I recieve my 7.62x39. Right now we only have that corrosive czech surplus stuff and there is no way in hell I am putting that garbage down the barrel of an XCR. Maybe a cheap sks but no chance its going down the barrel of a XCR. We just recieved approval for PMC in 5.56 and 7.62x51 so hopefully we will be able to bring in PMC in 7.62x39 before too long. By the way Prizm nice report and continue having lots of fun with it.

Good report, sounds like a fun little gun to shoot. Even though it wont be used in a benchrest type situation I would still be interested to see how it groups (to compare to other x39 offerings).

glad to hear the mags worked well. when the trigger and hammer stuff is fully ironed out this is a real winner.

how will the required trigger group changes for x39 affect my bill springfield trigger job?

Magik, I don't know I had my previous trigger worked on by a local guy, it was better than the stock one but still bad. I don't remember any changes with the hammer change but since the new spring... well lets just say the trigger is not fit for man nor beast. It's beyond bad and is roughly about 37 lbs. of long grinding pull. I'll have to have it reworked. I think you'll just have to take it on an individual basis. Wish I had more info for you.

So, to make the XCR 7.62x39 work correctly w/ GT (which is one of the most common/cheap and popular 7.62x39 plinkin' ammo out there) you had to replace the trigger spring and now it's 37 lbs. :eek: :eek:? And it was worth the wait? ??? ???

Hold on... another "taken completely out of context" internet moment. The statement about 37 lbs was sarcasm. I stated that only because my original trigger was not so great and I had someone work on it. After that is was actually decent. But since I changed the spring it's back to not so great with a little more not-so-greatness in there. It's got nothing to do with the 7.62 kit at all.

It's a simple fact GT might be cheap. BUT... maybe that's why it's so cheap. There has to be some limit on primer designs. The GT primers are ridiculously hard. These rounds should have ignited. The strikes were plenty deep enough. Maybe I got a bad lot. But I bought 2000 rounds of the crap so I have to make it work for me. If I could find the rounds I'd post pics but they seem to have grown legs and walked off. Everything else ran as it was supposed to with the standard spring.

Worth the wait?? When you shoot this silky smooth beast in 7.62 you'll know why it was worth the wait. There is significantly more oomph to it and it feels like that's what this gun was meant for. It's operation is dead on. It's nothing like shooting an AK in 7.62 and I can't imagine how brutal it would seem in an AR platform.

Seems to me that Robinson got it right. Now the fine-tuning comes in.

Ok, I found them. They had grown legs and walked themselves into a different room (that's sarcasm too). ;)

Here are some pics of the Golden Tiger primers. Again, I fired three other brands of inexpensive ammo and everything ignited except one round of Wolf. Something is up with the GT primers. I read that they were not as hard as Wolf Military Classic (not scientific, just internet here-say). I haven't shot wolf classic but if that's the case then the WMC primers must be concrete.

I've had bad luck with GT as well- my AK wasn't able to set off some of those rock hard primers.
