My SP5 see's regular range time, typically comes out with me every week for at least a couple huindred rounds, roughly 20,000 rounds in the last 2ish years.

 

That's a serious round count with a 10K average annual usage. If there were going to be any potential durability issues, they would have manifested well before the end of that first year, so that speaks volumes for the platform.

Are you running with a single-point sling attached to the back plate? An MP5 or a clone is on my wish list, and rather than go through the SBR rigamoral, that's how I intend to set it up when I get it. Nothing beats a real stock, though, but the only one like that I've ever fired was Army property.

 

Every time I go to the range I bring my elite 9 and sp5. Haven’t really been bringing the mk23 or hk45 along recently. My elite I have shot 1k rnds through it this year with no problems. Same with sp5. Every hk I have I shoot. Was gonna put the elite 9 away and not shoot it but that’s just kind of dumb to not shoot these guns.

 

Doesnt nasa have some mp5s that are at 100k rounds?

I put probably 2-5k a year on mine going by how much 9mm I’ve purchased in the last 5 years

 

With 10-20K-round counts on MP5s reported up to this point, I'm curious about how well the clones hold up. That's a lot more rounds than you typically hear reported through people's weapons.

 

If the barrel extension roller recess wear out too much, can that be remedied with a new locking piece, or does the whole barrel extension need replaced. I ask this because I have a PTR-91. I'm far from wearing that out, of course, but at some point in the distant future, it could potentially become an issue.

 

The rollers slide into the trunion fyi. Yes bolt gap can be brought back into spec by different sized rollers / new locking piece as it wears.

 

I fired about 4,000 rounds between March and December, 2023, and have a goal of 5,000 this year. I will vet a carry gun and then barely shoot it, and keep an identical training gun for practice.
