I’ll put a crisp 100 dollar bill that 99.89% of individuals on this forum will never be able to see the functional difference between a DI and a PD rifle.
I’ve yet to even see a Canadian civilian who even owns an HK 416 or one of those variants who doesn’t cry when their rifle bumps against one of their many other safe queens, let alone run it to the point in which a PD system could be considered advantageous.
On the civilian market, especially the Canadian civilian market, the DI vs PD argument is 100% moot point.
100% agree, It would take someone putting 2000+ rounds through both side by side to see any difference.
Explain then, how the Swiss Arms is such an extremely accurate gun then, with a big huking piston and gas block on it? Free floating is a ####ing meme. C7 isnt free floating either. No one is hurting for accuracy.
It isn't an extremely accurate gun unless you're talking about the $10,000 model that almost no one has because there are so few of them in Canada. I owned a Classic green flat top and it was no more accurate than any other semi I've owned. It was about the same as any rack grade rifle when shooting cheap FMJ, I'm sure it could have shot better but so could any rifle if you take the time to try different ammo and figure out what the barrel likes.
The worst thing about the SA rifles and also why I finally sold it was the massive shift in POI when going from bipod to supporting it on the magazine. I've owned many AR's and other non floated semis and none of them had that much POI shift depending how you held it.
Don't get me wrong, it was a beautiful rifle and was built like a tank, it was one of the most nicely built firearms I've owned but it wasn't any more accurate than anything else out there.
All this BCL 102 trash talk. I just bought one and haven’t shot it yet and now I’m scared.
I’ve had many NEA/BCL products with no complaints. Some of us can only afford kraft dinner. So let us try to enjoy our cheap guns and support a Canadian company. You have to remember, they haven’t been in the game for that long compared to some of the other brands. Mine seems well built and hoping for the best.
Don't be scared, at least they have a good warranty. I find it very hard to believe that any member of this site who spends any time at all in the black rifles or the modern military sections does not know about the BCL/NEA problems. When the 102 was released there must have been 5 threads on page one alone for the first 6 months with guys complaining about problems and talking about changing out every part on the rifle. How could you not have seen any of it?
Actually, the AR isn't even a true DI gun. It's a short stroke piston design, with the bolt/carrier doing the job of the piston/cylinder... And there are lots of short stroke gas piston systems, the SKS is one example.
For a true DI gun you've got to look at things like the Swedish AG42B... Nobody makes a true DI gun these days, at least that I'm aware of.
The best description for the AR operating system I've heard so far is to call it an internal piston design.
Rifles with it on the barrel would be an external piston design.
Check out the ADCOR. They came up with an ingenious system of mounting the piston in the free float handguard with a gas tube off the barrel to the piston. Piston function with free float barrel accuracy. I'm actually really surprised these didn't gain a lot more popularity. I think had the US M4 replacement competition continued that the ADCOR had a good shot.
It is/was a great idea, I am also surprised it wasn't more popular. We're kinda wandering back to where people are kinda neutral between DI and external piston designs but back then it was the latest and greatest to have a piston driven AR.
Generally speaking most DI guns are thought to hold the edge in accuracy but Gas piston guns are thought to hold the edge in reliability.
I'm going to go against this one for the most part. There might be a slight advantage to a DI rifle but I think it is very slight.
I've owned both types of AR's and my piston driven PWS with a 12 inch barrel would shoot about 1 moa with 77gr match ammo (same as my HK SL8-4) and I've owned numerous DI AR's that couldn't touch that with the barrel they came with. Because of this I think accuracy is more a result of having a quality barrel than whether or not it's free-floated or piston vs DI. If you install a true match quality barrel into any rifle it's accuracy will be improved drastically, certain rifle designs create restrictions to how much of an improvement you will see but in general the quality of the barrel and the quality of the ammunition will determine accuracy potential to a much larger and more measurable degree than simply whether it's DI or piston, or free floated vs not.
