My Rare Breed trigger showed up, and I'm picking up my SP5 tomorrow.  I'm having second thoughts.

Am I about to take a very high quality/reliable firearm and introduce uncertainty/inferiority?

Yes, it is a range toy, but am I diminishing the thing?

Do I just need to buy a clone to play with the trigger and leave the HK whole?

Thoughts?

Yes….unless you reload, are wealthy, or someone else is providing your ammunition.!

Do it.

The gun was meant to be full auto.

what not just try it out and see how it goes, and if doesnt work, buy a turkish clone and tinker with, if the turkish gun runs with no issues dump hk and buy ammo.

“Very high quality” …dude it is a mass produced stamped sheet metal & polymer firearm.  Don’t let the price HK charges fool you.

Slap the frt in it and blast away.

Only to your wallet for the ammo expenses.

I like my H&K stuff too, but people need to stop putting Oberndorf on a pedestal.

It’s just a trigger pack it’s not a permanent change.

You can put it semi until you want frt. 3 position selector

I’ve just put a few mags through it today…hot as hell outside.

The OEM trigger pack has a slightly better selector movement, but semi feels about the same.

The frt setting works great…I ran wwb and some sb subs.  I ran both supressed and not suppressed.  It shot great.

FRT mode is awesome…out of ammo so fast.

I submitted my form 1 today.  I’m looking forward to adding a stock when I’m able.

I can't speak to the FRT.  But I have an MP5 with a Franklin BFSIII trigger.    It improved the semi trigger and in rest mode it still feels great.

However, I dealt with your question by dropping it into a separate H&K MP5/SP5 SEF trigger housing so I have both.

it wont run quite as fast as a select fire MP5, but it's still fun, and useful if for whatever reason you needed suppressive fire or the ability to score multiple hits in minimum time.

Not at all. Think of it like those of us with transferable sears. It’s a host for the RB trigger group. All of my HKs are German and I shoot them all with sears and enjoy them. You don’t diminish the SP5 by shooting it. Enjoy your new pseudomachinegun.

I got a SEF trigger housing for the FRT in my SP5K.

My AP5P has a RB fun pack and it runs flawlessly. Will be putting one in its big brother, soon. It’s a game changer.  Pretty amazing how fast you can go through a 30 rd mag…(insert big smile..!)

Im gonna let the cat out of the bag here.   A semi auto only sp5 or mp5 clone is completely lame at this point.  Like totally.  A 1000% boring waste of time. Why would you not take advantage of this tech?
