Fn fal... piston love

Daewoo max/k2/200..ect...piston love

Two superb piston rifles.

Not sure why you would say..never buy a piston rifle, if you mean in an ar type, I guess so.

Ok, ill take the troll bait, only to point out the troll bait.

Has nothing to do with piston vs DI. Sounds more like low vs high quality.

You said their were 30 guys in the class and 6-8 DI guns having problems. Were you there with 22 friends with piston guns? Or were there some DI guns that didn't have any problems either?

This is why I laugh when people claim reliability after "ran 300 rounds at the range an no problems".

^^ Thank you for your post.

I did not want to say anything. Tired of reading B.S. especially from someone with over 2K in posts and still writes a paragraph like he is drunk. People who B.S. usually ramble words without knowing/realizing that the detail of what they spew does not match right.

Were the failures running Frog Lube?

I suspect home built guns, froglube, or weak ammo could be some of the causes. I previously owned one of the original pws piston ar's and while nice, really did nothing special over the di version. Instead of cleaning the bcg u had to clean the piston.

They said they only use SLIP2000.

So it most likely did

Enough information here for me never to buy a piston setup

Great link, but....

seems like the least relevant type of info for anyone EXCEPT a "high volume range" where the range provides all guns and flogs those guns far beyond even the most extreme military use.

I'm not gonna care what a long haul trucking fleet manager says about tires when I'm buying tires for my next motorcycle race.

If the OP's experience was the same for all DI guns, we'd have a whole lot more dead servicemen in every conflict we've fought. There would be a huge outcry from military's around the world over a 20% failure rate in adverse conditions.

Those students were running absolute garbage and/or never cleaned and lubed their weapons if the OP is telling the truth.

Good info. Interesting that the PSA uppers are performing as well as the LMT's and Daniel Defense's. That mirrors my experience.

Should I now sell my Daniel Defense upper to replace it with an Adams Arms? Nope

The range masters changed a few gas blocks and rebuilt a few BCG's


OP-
What class?
I have attended a decent amount of courses.....across a number of schools....


I have seen all sorts of firearms break.... but never an instructor rebuild a BCG....


What school? Website?

Amen to that. Even the thought of letting someone else have my DDM4 makes me cringe.

It was the 2 day carbine with Firearms Training Associates at Rahauges...

Overall a great class! I liked their style better than Front Sight (granted I took the handgun at FS)

A milspec DI rifle would allow me to sleep well at night.
