FWIW, the heaviest weight adjustable works just fine in my 4.5" CMMG barrel with CCI blazer and minimags. Standard recoil spring, standard hammer spring. I got it for less port pop suppressed, but works just fine unsuppressed.
Thank you. This might help with why I’m grtting trigger reset issues on a 4.5” with all the stainless weights inside the aluminum weight. I’m having the worst time getting the damn thing to run reliably. Feed issues, extract issues, trigger reset issues, light rim strikes, bolt hanging up on the mag catch… just about every kind of malfunction there can be, I’m having. That’s with a RTB bolt but all the bore buddy upgrades. Their machining quality seems way down compared to a friends bore buddy bolt he just got.
Have you messed with tungsten / tungsten carbide weights? I'd assume cutting up some drill bits would do the trick. Just to get the weight up even more.
What would you start with when tuning for your 7" dedicated? The lightweight or AL carrier and which weights, Stainless & Aluminum? Does it really need to be divided equally?
I'm wanting to use your conversion bolt to shoot 22 in my 5.56 upper for practicing drills, I have a couple thousand rounds of federal 1050fps ammo that I couldn't get to run in my 10/22, would that conversion bolt with your 3lb recoil spring be enough to cycle them reliably as possible?
It should, as long as your upper is 14.5" or longer and has a rifle or mid length gas system. If the barrel or gas system is shorter, you may have more trouble. Closing the gas port when shooting 22lr is advisable. An adjustable gas block is a great addition if you're going to shoot both r22lr and 223/556.

Good to know -- sometimes it does work, most of the time you need a lightweight. Every build and lot of ammo is so different.
Good to know,!

Yep we have tungsten inserts on hand here, but nearly all setups don't need that much added weight.
What do you recommend weight set up for running a 4.5” barrel with a FRT. Running standard velocity ammo
Just ordered a 4.5" upper with the regular weight kit because I didn't know any of this.
What would you start with when tuning for your 7" dedicated? The lightweight or AL carrier and which weights, Stainless & Aluminum? Does it really need to be divided equally?
Which one do you recommend for your 21" match upper? Going to run match ammo.
stainless adjustable.
12.5" suppressed, dedicated upper, shooting subs. Which kit?
will these fit the chiappa dedicated upper?
No.
Exactly what I needed to know
