SVT-40 IA's and Stoppages Question

[summerside sniper]

I am hoping to recieve my SVT-40 before I sail on the 19th of June. The info that I have on how to operate, maintain, disassemble and assemble is really good except that it does not include very good info on IA's and Stoppages. Can someone help me out? I know that this is going to be very important because as soon as I get out to sea and I (and by I, I also mean the whole ships company!!! ) want to shoot it, I need to know this in case something bad does happen.

sorry to hijack, but you can take guns on the ships and shoot them? Wow, +1 for the navy!!!!

Most stoppages with the SVT are caused by an incorrect gas setting. Make sure you have either the proper gas regulator tool or other device that will allow you to loosen the piston and rotate the regulator. Check your magazine for proper feed as well. A-Zoom makes 7.62x54R snap caps for this purpose. Some, but not all SVTs use a fluted chamber to assist extraction. Check your extractor for proper function.

Stick to tombac ("brass" coloured) steel cases. The Czech laquered steel case rounds may adhere and fail to extract after the chamber gets hot. Found this to be the case when used in my Mosins.

Lastly, familiarise yourself with field strip & assembly.

The gas regulator on the SVT is one of its more enlightened parts. But it is easily misunderstood and maintainence overlooked by shooters not familiar with its role. The SVT was an inspiration for the smartest gas regulator system ever fielded, the FN FAL (aka FN C1A1).

On the front slope of the gas block is a five-sided nut. On top is a tiny hole, like the blowhole on a miniature whale. Inside the gas cylinder chamber, the gas comes off the bore, through your chice of five progressively different sized small holes, through a plug that threads into the gas block, into a stamped steel expansion chamber where it pushes the operating rod. The shooter chooses the setting according to the amount needed to cycle the parts softly enough for comfort, but hard enough to function.

The tools you will need are a small adjustable wrench to turn the gas plug and a five-sided wrench (or pliers !) to turn the gas nut.

The IAs and Stoppages for any semi-auto, including the C7, will work for the SVT. An empty magazine will engage an holding open device. New magazines rock into place (unlike the C7), and can be topped up in place from stripper clips. When you have the parts cycling, experiment with closing and opening the gas for comfort.

All you need to do is some easy paperwork that goes to the Captain and any ammo and firearms you take onboard get stored with the ships stuff. People do it all the time!

Thanks for all the IA's and Stoppages help! If any more useful info that I could use, please send it to me!!

The gas regulator on my SVT was so tight that it could not be adjusted with pliers (and crappy tire doesn't sell 5 sided wrenches ). I tried the "loosen the gas cylinder then adjust the gas regulator with your fingers" method but even after taking off the gas cylinder the reg was still very tight. I thusly rigged up my own ultra crude (in true Soviet fashion ) tool; a small 2mm thick piece of flat steel bar with a hole drilled about 1.5mm from the side and 1.5mm from the end. I made the hole slightly undersized then found a similar 5 sided nut and hammered it into the hole (therefore creating the same 5 sided pattern in the metal). I took out the nut and tried the tool on the reg. valve and it works great.

Ill post a pic if I get the chance.

After you remove the gas tube, you can tap the regulator out through the opening. Then you can rotate it and reinstall it, if it's too tight to turn in place.
