| I have had a sar-1 for a wile now. I got tired of all the problems I was having with it. (Mostly reliability) I think the problem is the welded in gas piston. I have an arsenal sa m7 carbine on the way. I was thinking when it gets here I could take the piston and bolt carrier (but not the bolt) slap them in the old SAR and see if that is the problem. Origanally I was going to get rid of it but then I thought it would be cool to not only have and AK-47 but allso an AKM... kinda want to keep the old SAR-1 around... I will just order a new carrier and piston from K-var.. |

| It isn't very difficult to fix a rigid piston. You have to drive out the pin that is holding it in, then back the piston out until it has just a bit of wobble then drill into the threads through the original pin hole, and drive the pin back in. You will have to perform the same procedure with the new carrier/piston anyway. Remeber that on a SAR series rifle the piston is a US part, so if you replace it you will need to replace it with another US made part. |
| yeah it is pretty damn solid that is why I think it is the problem. I know about the whole US parts count BS so if I replace the piston it will be with a US one. to fix it I would not be driving out any pins as the century monkeys welded the damn thing in. I have tried in the past to drill out the weld but that did not turn out to great. I just want to know if I can test the rifle for reliability with the bolt carrier and piston from the milled bulgarian Ak |
WTF are you doing up ???? It's 4 fukin thirty in Wa. ........... :) edit: Oregon ... Sorry  edit: I'm trying to buy that rifle ... Quit being so Sweet !! edit: How did that sling I sent ya turn out ? ... Is it Purple yet ? |
|
its 5 in the mornin i cant sleep i took some pills they knocked me out yesterday and now i cant sleep cause i took a 5 hour nap :/ O happy day its not purple yet i orderd what i thought was a good match of webbing and it turned out it wasnt even close so i sent it back and orderd some mo |
Sorry 'bout highjackin' the thread man but I don't think it's wise to start swapping bolt carriers and bolts without a qualified person (gunsmith) checking the headspace ... If you have a set of "Go/NoGo" guages and know what you're doing it's fine ... Just my opinion ...  Also think I remember that the Romanian bolt and carrier are a little shorter than other AK's ... If this is true it might cause a problem using a Bulgy setup ... If I'm wrong someone will correct me I'm sure .... PS: "NO" was a very blunt answer to your question ... my apology !! |
|
your wrong LOL i dont know if its shorter i know it works cause ive done it b4 put the milled carrier in rommy and rommy in my milled (rommy was polished and i thought it looked good in my milled) but that is why i asked where he was i have 1/2 dozen diff carriers he could try and go/nogo's |

The head space is done by the bolt not the carrier. However, the other carrier may need to wear in a little to function. That said, I had the same trouble with my SAR1 as the piston was welded into the carrier and I just 'fixed' the piston problem. On top of that, after I milled out the weld and got some play in the piston, I went to drill out the hole to install a rivet, and found that the piston that century had used was hollow right where the threads are (inside). So, when I went to install the first rivet, the rivet shaft bent inside of the hollowed out area. I did finally get a rivet to hold, but I have not shot it yet. I did let the carrier slam closed about 70 times to test the rivet. The first rivet failed after 20 closings. I would just unscrew the piston, but it gets stuck part way out and I am afraid to strip out the threads on the carrier. so, if I unscrew the piston successfully, a new piston is $20 (US made), but if I fubar the carrier, I get to spend even more. With the hollowed out area, I see why Century choose to weld the piston in place, even though it gives no wiggle to the piston as it should have. The piston needs wiggle room because it is suppose to be a sloppy gun. Sloppy makes things less accurate, but more reliable. As a side note, the piston on my WASR10 wiggles much more than my newly fixed SAR1's piston. |
