Tradex is a responsible dealer. If you receive a firearm from them that you feel is unsafe, they will take it back with a full refund and shipping on their dime.
Those Mosins are pretty much as described, FIELD GRADE. FIELD GRADE means used/abused/worn/mixmasters, examined/repaired accordingly and still considered to be safe, capable and within acceptable specs to perform their duty on the battlefield they are qualified for. DON'T EXPECT ANYTHING ELSE.
If you get one of the cleaner, maybe even all matching rifles, BONUS. If you get a rifle with a 90% or better bore, BONUS.
Several years ago, I went through the Anniston CMP distribution center, with a friend that volunteered at the facility. Nice guy and very knowledgeable on US military firearms repairs, etc.
When I was there, they were working on a few M1 Garands, which were in short supply, to fill orders from qualified persons. All of the rifles were FIELD GRADE. All were serviceable. All were mixmasters, all were well used and showed it. The armorers checked the throats, bores, muzzles for wear with hand held gauges. Several were being set aside for the FAIR ONLY RACK in the sales room. All of the FAIR grades needed small parts or stock repairs. All FAIR grades would have been safe to shoot. Then there was a small bin of rifles being set aside, to be stripped for usable parts.
The grades ABOVE field grade, started at twice the price of field grade, right up to collectible and auction status.
Tradex isn't offering FTR rifles that used to be the norm. These are LESSER GRADE and as the Mosins seem to be drying up in Canada presently, they are priced accordingly. Likely with about the same profit margin of previous rifles. They're getting to be more expensive and difficult to get out of Europe as well. The surplus stocks will dry up, if they haven't already.
If you want one of the Tradex Mosins, give them a call. Talk with Anthony or his Dad and ask them to pick out one of the better rifles. They're usually pretty good about that.
You may also want to try Weimajack, another paying dealer, whose ads appear in the yellow tinted threads in the EE section. He often has some decent, matching examples but they will be more expensive than the Tradex offerings, as condition warrants.
