So I'm reading one of my gun mags, and came across this article.
Although I've never delved into this area, and am only familiar with the historical glow of the MP5, I became intrigued about how the whole platform works.
And now I'm seeing that a budget build in .308 can be had for around $600, that's reliable as the day is long??? Not intending to torture test it, but I can see getting back into .308 with this interesting platform.
As a side note, along the same platform, I'm literally drooling over the coming of the "working man's" MP5, the PSA5.
Trying to figure out how to pre-order it and get these night sweats over with.

 
I traded into a PTR 91 GI many years ago with a fellow board member. Very nice and dependable piece, but, the ergonomics finally drove me to trade it off.😠

I still have a can of mags for it, with a new firing pin /w/spring and a set of #2 rollers,... just in case I ever wore out the originals.😀

When I read about Savage's 17hmr and 22mag delayed roller lock semi-auto;s,... I was, and I am still tempted to buy, just because!

Now that you have my attention,... which 308 roller lock rifle are you talking about?
 
My PTR-91 shoots nice little clover-leaf groups and recoils almost as softly as my FALs. I have no desire for another, but it's not going anywhere, and I'm sitting on a pile of mags and spare parts.

I dunno, I just see that it says in the intro to the article I pictured says 308 kits can be had for $600 with CETME parts.

I bought the Savage A17 when it came out, and haven't regretted it since. It's a roller lock, guess I already have that platform......
A friend turned my attention the the round long before that, and it was just about the time that articles were saying that Savage has figured out how to make a semi-auto hmr17 that doesn't jam.
After about 400 FLAT shooting rounds, I don't recall a single malfunction yet.
If you're on the fence, feel free to get the cobwebs out of mine sometime, and you'll be buying one.
 
Those $600 Century rifles are their current production C308 model. The quality of those is VERY hit or miss as the parts are bottom of the barrel surplus parts kits.

I have two PTR91 GIR rifles and really like them. Though the LOP is a bit long for those of us with shorter arms. I just converted the plastic furnitured one to utilize the Magpul UBR Gen2 adjustable stock and am pleased with the results so far. The other rifle is stocked with surplus wood furniture and thus won't get an AR style stock.

I picked up a buttload of surplus G3 mags ($3ish a pop) when I bought the rifles.

You lost me at "Century". I joke, but I've had a few bad experience with their AK's. I trust PSA to make a good product. I talked to a few of their engineers at SHOT last month, and they know what they are building...a stamped/folded piece of metal seems simple, but it isn't.
 
As a re-loader I dislike the chamber flutes left in fired cases from a roller lock G3 or PTR-91. They eventually flatten out but I still don't like them deforming the brass.

+1,... just one of a couple things that I didn't like.

I didn't like the bolt release!
I didn't like the the trigger!
I didn't like the the mag release ergonomics!
I didn't like the sights!
I didn't like the claw mount scope base!
I didn't like the the overall balance!

Win308 seats on the shoulder,... shoulders that don't fit the chamber perfectly, are not to my liking,... period!

Thanks,... but, I have read way too many complaints on CETME over the years, to take a chance on getting a good one.

On better quality brass you simply get carbon streaking and not deformation.

The current C308s are assembled by Century on PTR built barrelled receivers. PTR also handles the warranty work.

The issue comes in that CETMEs were never very plentiful to start with and the parts kits are in very limited supply (which doesn't bode well for finding spare parts later down the line either).

From all reports the first run of the C308s were not too bad when Century could hand pick (several people over on AKFiles gave good reports) but as they got closer to the bottom of their parts supply unservicable parts started getting installed. Atlantic Arms even stopped carrying the C308 due to quality issues.

PSA is having teething issues on breaking into the AK world but their Gen3 is looking good in RobSki's (and others) testing so far.

He was offering you a chance to try out his A17...not a CETME.
 
The PTR rollers are good to go. We just got the PTR 9CT and broke it in today as a post sample and it went 600 rounds without a flaw. We started off doing their break in routine they recommend but after 100 rounds and 3 cycles of breaking it down and cleaning on semi auto we said fudge it and rolled through the last 500 brrrrt after brrrrt. For a what $1600 street price MP5 it's great. Debating buying a 7.62x39 version and doing the same. My shop monkey has their G3 version in 308 and it runs great. If you want to do a old tyme 308 from the days of heavy shitty rifles go for it. Otherwise go build a nice 308 AR or take out a second mortgage and buy a SCAR.
 
I was sorting thru some brass yesterday and when i quizzed a gent that was working with me on it, the markings on some of the 9mm, he said it was from an mp5, as it leaves the long straight markings on cases, interesting guess we will see after cleaning and polishing and if they reload ok, or ...................

i would like me some mp 5 though.

Better Quality Brass ?? LOL come-on...
I've reloaded enough of it to have a different opinion...
The chamber is fluted and firing pressure will expand any and all brass to conform to shape- as part of the extraction system it is designed to provide more frictional delay, allowing pressure to subside before the rollers take over. It is essentially a blow-back system. If there are only carbon marks from the grooves, it's because the chamber is carboned up from lack of cleaning of blowback over several thousand shots.
