I had a front trunion break recently. Called century & they referred me to a gun smith since the warantee was only a year. The rifle has about 15k through it & was very well maintained. I noticed sometime ago the trigger pin hole was soft & wearing severly. I made a bushing & put a hardened screw through it. worked great until the truion broke 500 rounds later. Needs receiver & trunion fitted. The smith I talked with was up to around $250.00 to repair it. Thats 75% of the cost of a new wasr. So much for a 50K service life. I'm thinking scrap & use for parts unless I can find someone to do it cheaper. Any ideas?

Have the receiver BATF cut, and order yourself a new receiver and trunion and build it yourself.

pics of the breakage? Is having the existing trunion welded to repair it out of the question?

If the trunion can't be repaired in place, then you're looking at having to remove the faulty trunion from your receiver, install a new trunion, remove the barrel from the broken trunion and install it to the new trunion. If you can't do that work yourself to keep the cost down, then you might be better off getting a new rifle. Too bad there are no more SAR1s, so it'll have to be a WASR or something.

The trunion will have to stay with that receiver due to it being the serialized part of that receiver. Looks like he has an incomplete parts set.

the trunion is cracked , so it would be an incomplete parts kit but that has nothing to do w/ the ser# of the trunion and receiver. the only part that is regestered is the receiver. * edit * ok,i looked at my sar-1 and i see what you mean, the receiver has no ser# just the trunion. in that case if it cannot be welded in place it would prolly be cheaper to just find a different rifle.

Correct. You could cut the rifle and sell it as a partial parts set to recoup your costs on the new rifle.

Since I don't have the press & dies home repair isn't a option. Does anyone make a quaility receiver with trunions, mag release & trigger guard installed as a reasonable price? That would leave pressing the barrel & head spacing. The problem is that something else could break judging the quality of this rifle. My friend & I each bought SARs at the same time. He has had no parts breakage of any kind with his & serial number were the same year & close. His trigger pin hole is begining to wear but nothing like mine. Both have a comparable number of rounds through them. Recoil spring assembly also broke on mine at the tongue. luck of the draw I guess. It looks like I'll be investing the $250.00 in repairs on a higher quality AK to replace this one.

Sounds like you've got a used chrome-lined romanian barrel, some used AK furniture, a full stamped AK fire control group with US compliance parts, and some other miscellaneous AK parts to post up on the EE, then. Good luck on your sale and your upcoming purchase!

Thats the plan. Looks like they went up on the saigas.

If I cut the reciever in half through the mag well will it be legal to sell? Obviously the trunion holds the serial# but its broke & would have to be replaced. Is it still considered a complete rifle with the serialized trunion?

You have to make 3 cuts through the receiver, each one taking at least 1/4" of material. OxyAct torch will do the trick.

Any particular area to make cuts? I have a cut off wheel in a compound miter saw that should make light work of it. I may have to cut each area twice to meet the 1\4" width. Cutting\removing a section of the magwell approx. 3" area behind the front trunion to the mag release. Do the same behind the trigger guard to rear trunion. I suppose you could make another cut between the trigger guard. Would that be sufficient? That still leaves
the serial # on the trunion, is that legally a firearm even though its broke?

I'm at work and will have to look up the details. But I think the requirement specifies that it be torch cut, but I could be wrong. I'll update when I get home.

I believe this is what you're looking for. The torch cuts are only really required for machinegun receivers - not sure if ATF's ever ruled on what constitutes sufficient destruction for a non-NFA firearm receiver to no longer be considered a firearm
