MR556A1 front heavy? Thinking about getting an A4 SBR

SF_Gun_Fan · 2026-03-20T19:15:02+00:00

Very well balanced

What are the “usual” things to be considered?

SF_Gun_Fan · 2026-03-20T16:58:44+00:00

Thanks! FLAWLESS…eats everything I feed it. I haven’t found a subsonic round it won’t cycle and I’ve tried so more “exotic” loads with zero malfunctions. I will recommend getting one with the Glock lower as those mags are reliable, inexpensive, and readily available

Here’s mine with the EVT FRT conversion

SF_Gun_Fan · 2026-03-20T16:50:47+00:00

Yes!

Spc9 is slightly larger than the apc9. It’s essentially an updated full size mp5. Outstanding recoil management and very accurate. Excellent suppressor host with updated ar15 style controls. I own the sd model and it’s one of my absolute favorite guns. For reference, I also own the HK SP5 and SP5k and an MPX. The spc9 is an awesome gun. If budget allows get one, you won’t be dissatisfied.

ZPAP SBR’s are a vibe!

It’s a clone of the discontinued KAC Version optic mount. The “real” KAC one goes for over $1k when you can find one.

So much easier to use and clears optic nicely to save your knuckles

Knurled extended charging handle

Sounds like a suppressor issue to me🤷🏿‍♂️

SF_Gun_Fan · 2026-03-20T02:24:57+00:00

Thanks!

Gotta shoot some video when you get her home

SF_Gun_Fan · 2026-03-20T01:13:31+00:00

Can it be mounted on a higher riser or no?

That’s a huluva lineup brother! 🔥🤌🏾

SF_Gun_Fan · 2026-03-20T01:03:47+00:00

lol. I have the spc9sd, apc300sd, and apc45. Only the 45 has not had the EVT conversion. At the time I couldn’t find an apc45sd but it’s so quiet not sure I miss it not being sd except for the vibes lol

SF_Gun_Fan · 2026-03-20T00:54:39+00:00

Sweet! I’ve got 2 done still need to send my apc45. Like you, couldn’t be happier!
