Re: Can anyone recommend a really good 5.7x28 ballistics scope?

I wish my Vortex SPARC II red dot had a circle/dot reticle. Then I'd have two aiming points, one for 5 - 15 yards and one for 50 - 100 yards. They would at least get me in the ballpark.

Re: Two NEW firearm models chambered for 5.7x28mm by EXCEL ARMS

I'd buy a pistol in .22 WMR if the barrel were, say, 5 or 6 inches. Eight inches for a .22 WRM pistol barrel is a bit too long for my taste. But the price is OK.

P90 5.7 x 28 v.s. MP7 4.6 x 30 ammo

Since the Germans just had to re-invent the high velocity sub gun ammo wheel have there been any comparisons of the P90 ammo and the H&K MP7 ammo. With a smaller bullet the MP7 round likely travels faster than the P90 round but it will retain less energy for CQB battle which is usually within 25 met...

Re: Ammo Question:

Right! Elite is the one "smaller" fabricator of 5.7 x 28 ammo that I trust. And they seem to have about the same velocity as FN.V-Max ammo in most of their loads. I've seen Youtube tests of FN, AE, and Elite ammo on 3/16 wall square steel tubing fired thru a PS90 SBR. The FN and Elite ammo did prett...

Re: Ammo Question:

Are there other small 5.7 x28 ammo makers that produce reliable as well as "speedy" ammo? (as in a bit faster than FN ammo) During "The Great Ammo Shortage" one custom loader has so many requests for his ammo that he quit taking orders so he could fill his months of backorders. I'll have to GOOGLE h...

Re: How much velocity is lost with an SBR?

Thanks for the prompt reply Buffman. I can live with a 100 FPS loss for a CQB weapon. I use FN ammo, which from testing I know is faster than Federal's American Eagle ammo. And I also know that, even with 100 FPS slower velocity, it still has much more energy at 100 yards than the tiny ammo from the...

Yep, I've noticed my American Eagle ammo shoots lower than the FN ammo. Lower = slower. 'Nuff sed!

Hmmmmmm... I have some Teflon bike chain dry lube. I've used it on my sliding door track and it works well. Maybe I'll try it on my PS90 action.

Re: HK MP7 chambered in 5.7 x 28

Yeah, H&K fell prey to the mostly American syndrome of "Not Invented Here" (the P90) so they invented their own sub gun that would defeat Level III soft body armor. And so they did, developing a cartridge that has less kinetic energy downrange than the 5/8x28 and a gun that is good but not as innova...

Re: Optics Conundrum

I put a Vortex SPARC II red dot on my TROS Low Mount and it comes up perfectly to my line of sight every time. I bought it from Optics Planet for $180. This scope has all three tethered caps (battery and windage & elevation) and comes with plastic scope caps and high and low mounts and a 1/4" shim f...

How much velocity is lost with an SBR?

When I go to an SPB how much muzzle velocity will I lose with that lost 6 inches?


Q. Why are women such a bad judge of distance?
A. Because men have them convinced that this 8--------------------------------------<) is 6 inches. ;)

The Vortex SPARC II ships with a low mount And high mount and a shim as well. The shim can be used with either mount. With the TROS Low Mount and the SPARC II low mount my eye comes right up to the sight line every time. No need for an aftermarket cheekpiece. MY PS90 MODS: 1. CF reinforced polymer e...

Ammo Question:

Is Federal American Eagle ammo as reliable as the original FN blue box ammo?

So far the American Eagle ammo I've shot (50 rounds) has functioned well. Seems to have the same ballistics and accuracy.

Re: HK MP7 chambered in 5.7 x 28

HK went their "OWN WAY" and made an even smaller cartridge for a sub gun to compete with the PS 90. It is a "standard" format sub gun with none of the innovation of design found in the revolutionary P90/PS90. The Krauts were too proud to use the P90. "Pride goeth before a fall." But I like Danesthes...
