HK MP5 22LR

[Archer1440]

I don’t know what they changed.

But this trigger is pretty darn good.

@Archer1440

Does this qualify as being able to run fast enough?

15-16 splits. If I got used to the gun it would be more consistent.

Yup, sure does. Both my Hammerli and HK416 versions of this action will do 0.14-0.16 quite consistently- the takeup and resets are very good on both of those. I’m sure with a bit of trigger time you can do better.

There’s a nice feature where there’s adjustable bolt speed for different ammo.

That should increase reliability especially as things get gummy and dirty.

As a practical matter, I’ve never had to touch that on either the Hammerli R1 or HK416 versions of these actions- any decent quality .22LR has always cycled fine, even when the actions are filthy. Generally running Winchester (some of which has had a lot of primer issues unrelated to the firearm), Aguila, and Federal in the 38-40 grain ranges. (The Aguila 38 grain “super extra” runs particularly well, despite the cat urine odor.)

I’ve never run Remington anything in these.

I have a lot of guns and I think this is probably one of my most vary favorites.

As a trainer I think 22LR is very good for 9mm MPX PCC training since it’s mainly mechanics over recoil control.

I’ve now run this for a couple hours and it’s been excellent.

I am loving it.

1913 rail attachment and used an MPX stock.

Clearly a big improvement if it came out of the box that way.

I have a several year old 416 with a Romeo 5. I got a threaded adapter so I can run my Octane 45 on it. The adjustable bolt is handy for tuning between super and subsonic ammo for sure. With the can and subsonic ammo it sounds like a BB gun. The trigger is horrific-I didn't know it could be tuned but since others have referenced swapping springs I'll have to look into that. It certainly is a lot of fun for cheap.

Ordered the HK adapter to thread 1/2-28 to the pencil barrel.

Removed the very heavy shroud.

Without the shroud it might actually make a decent plinker for my daughter when she gets older.

I put my tiny Gemtech Aurora on it to save length and weight.



I could put a muzzle brake on it.

I am thinking of cutting the front iron sight off so I could mount a lower optic.
