SCAR Testing Review Military

[jdun]

He keeps changing the subject and dodging valid points that are made in the thread.

Anyway for those of you that are interest on how the AR15 DI works and wonder why AR15 DI has a piston click on the link. It's a very simple system and all done in a nice compact package. If you still don't understand it I'll try to explain it as best as I can.

Also, discussing the (alleged) faults of the 5.56x45mm round seems irrelevant, since (1.) everyone, including the Russians and Chinese, use smaller calibers nowadays, and (2.) there are AR variants available in 7.62x51mm. If caliber is your biggest grievance with the AR platform, then you have no legitimate complaints.

As much as I do like the SCAR, my stance on it remains the same. I still have my suspicions that this "Special Operations rifle" (the 5.56 version at least, I imagine the 7.62 version will see some use) might end up sharing the same fate as the Mark 23...

What I don't get is that if SOCOM wanted a gas piston so bad, why didn't they just buy an HK or LWRC upper, slap it on an M4 lower, and be done with it at a fraction of the cost?

Well, chances are HK would charge out the ass for theirs, but I'm sure you'll understand my point.

Or maybe I just answered my own question or something, I don't know. They deemed this civvy unfit for military service...

Well jdun you mind me asking your experience with the ar-15 platform? Just curious.

And Id love to see LWRC uppers. Also, the dust test had multiple m4s, I knew youd try to discredit it, all the AR fans do. My friends dad has some manuals left over from his GM days, the m16a3 manual says that its important to learn SPORTS because you can expect at least one jam every 90 rounds.

I own four complete Ar15. I have six complete lowers and four complete uppers. I have tones of AR15 strip lowers. I have built a lot of AR for friends and relatives, but not in the "thousands".

I shoot a lot and have a lot of different type of firearms in my collection. I been shooting since I was a kid.

The SCAR weakness like all AR18 action is in the recoil spring. The AR18 action require two recoil springs to function property. One recoil spring can't handle the load for long. It will loose its strength around 800 rounds or so depending on the quality of the spring.

Once the elastic limited been broken, more malfunctions will occur.

The modified AR18 action in the SCAR probably added a thousand round or two before the limit will be reach. I doubt it because I get the impression from the report that he wasn't the only one that is experience a high rate of malfunctions.
