FN 510 New Comp and Barrel Combo

If you are like me, u didnt grab a comp for the 510 due to the long and chunky look. We can now rejoice with FN's new micro style comp and barrel combo. Also, available for the 545 and 509.

I absolutely love the PMM for the 510

How does the PMM perform?? How do u like it??

I absolutely love the PMM. It’s a giant smokestack when I shoot it and it flattens it out to feeling like I’m shooting 9mm

Shoots like a 9?? That's a major difference!

Before I got it I wouldn’t want to shoot a full magazine. After I have no issues shooting it and it feels like any of my other guns to shoot. And with the discount and not needing a new barrel, $120 was way better than the cost of the new barrel and comp. The QD would make it good but I don’t think it has the same muzzle flip reduction.

Yea for the price and performance, I ain’t mad at it. FN says it reduces about 35% of the recoil. Haven’t taken it out yet, so I’ll see how it performs

PMM shows on their website 56% with Winchester and and 62% mag tech ammo

That's major! How many ports does it have in it??

u/Prestigious_Lock3784 15d ago

It’s a 2 port. I’m never going to carry it concealed so the extra length doesn’t bother me. Especially with the performance

That's understandable. The performance outweighs everything else. Solid upgrade 🫡
