WildPete Posted January 3, 2023 Share Posted January 3, 2023 I just finished installing the Gen 2. You no longer use the bumper in the tube when installing. I didn't see it in the instructions stating other wise but a quick message to Corey verified my initial thoughts. I will do the break in tomorrow and if I have time will tune it to my ammo.

Seanzky Posted January 3, 2023 Share Posted January 3, 2023 (edited) I just finished installing mine as well. I watched his installation video on YouTube prior and the actual install was a breeze. It took me from start to finish about 10 minutes. I'll be tuning this to my loads as well, but first I have to chrono my new recipe and see if it makes 135pf. Update: Just an 'initial impressions' update to my post above... the hold is pretty strong. I understand that there's a break-in process and I'm hoping that it will lessen the hold a little. Pulling on the charging handle, I can just imagine how hard it will be for shooting stages where a reload is mandatory. Other than that, the only other thing I can say is that if you have sensitive olfactory senses, you will smell the metal on metal rubbing inside the buffer tube. It seeps right out of the two holes. Haha. It reeeally smells bad. Unfortunately, I'm one of those who can smell anything and everything from a mile away. I still very much look forward to breaking this in and then tuning it to my reloads, though! I'm very excited. Edited January 4, 2023 by Seanzky Link to comment
mrvip27 Posted January 4, 2023 Share Posted January 4, 2023 So does this short stroke the gun? Link to comment

In fact.. with its super light action spring.. I feel it needs the “running start” to function at its best. I say this as a Scheel user that came from a Kynshot 5020ss Link to comment
Racinready300ex Posted January 4, 2023 Share Posted January 4, 2023 +1 on I don't think you really need to short stroke with the scheel system. Link to comment
CClassForLife Posted January 4, 2023 Share Posted January 4, 2023 Anyone put the Scheel buffer in a JP5? Link to comment
brian45acp Posted January 5, 2023 Share Posted January 5, 2023 I examined mine today in hand and its really well made. I did notice one bearing is a bit gritty feeling and hard to roll. I oiled it up and think its just because its rubbing inside one of the arms. I imagine break in will free it up a bit more. I did order the short stroke bumpers and another set of blue springs to have on hand. Above I see it mentioned no bumper needed so now I wonder if I shouldn't have bought those. My idea was to use the smallest one so when the roller bottoms out the blue rubber from the buffer bottoms into the black one at the end of the tube. Should soften the blow a bit and I do want to play around with short stroking and not lose any trigger speed. Link to comment
Seanzky Posted January 5, 2023 Share Posted January 5, 2023 Both of the bearings on mine don't roll freely either. They don't free wheel and spin. When I roll them, it's choppy kind of like a volume knob with clicks to it. I think this is normal, though. Link to comment
brian45acp Posted January 5, 2023 Share Posted January 5, 2023 yeah mine feel like that as well. Hold it up to the light and you can see the bearing is to one side in the arm and touches but other side doesnt. I think the roll pin tightly holds them but as it was driven in traps the roller to one side and it stays there causing it to drag. I oiled mine and rolled it by hand along my cleaning mat for a while and it seems a lot better. I emailed Corey to ask about it but I suspect it needs break in. I took a sharpie to make a line and watch it if it rolls or not and once inside the tube it seems to roll fine. We dont want these to drag or it will really wear it out. Link to comment

Mine doesn't behave like that. There's no drag in mine. It spins fine, but not in the same as a bike's wheel would spin freely. When I turn it, it turns but consistently choppy like there are detents. I also held it up to the light and both sides of the bearing seem to be equidistant from the arms. I'm glad yours seems to be rolling better after oiling, though. Link to comment
brian45acp Posted January 5, 2023 Share Posted January 5, 2023 (edited) We are describing the same thing differently. Mine rolls but feels choppy like you describe as well. Corey did reply and said this is fine and has no effect on how it functions but if there was ever an issue he would take care of it. Edited January 5, 2023 by brian45acp Link to comment
Mal223 Posted January 5, 2023 Share Posted January 5, 2023 I've had my Gen 1 Scheel RDBS in my ATI PCC for almost a year and many thousands of rounds. From day 1 it has been a soft shooting low bounce system. I saw on several posts saying it is difficult or hard to charge. I can't imagine what would cause that issue. I can reach out with my index finger only and fully cycle the charging handle with VERY little effort. It's about the same effort required to charge my AR-22's. I'm using the heavier of the two recoil springs and one heavy and one medium spring in the main buffer device. The rollers in my system spin freely with no wobble or gritty feel. I followed the directions exactly and I couldn't be more pleased that I bought it. My PCC load is a 147 grain plated bullet that chronos at a 150PF. Link to comment

Dirty_J Posted January 5, 2023 Share Posted January 5, 2023 The buffer is MUCH stiffer when brand new than after the break in process. It’s hard(ish) to charge until then with most of the spring configurations. Link to comment

Mine isn't broken in yet and in addition to that, I have a Hiperfire trigger which adds to the forward pressure on the bolt. Link to comment

Jrcnky Posted January 7, 2023 Share Posted January 7, 2023 just got my gen 2 in today and pieced the lower together and stuck my temporary 16" upper on. Going to break it in tomorrow. Took BCG weight out, using 2 heavy and 1 light spring with some 147 grain factory ammo. Mainly just shoot 124-147 grain factory so should be pretty consistent. Will bring buffer spring set with me to try some combos out if I have time. Link to comment

Couldn't get it figured out at range. Same upper including BCG ran fine with other lower the other day. Took weight out of bolt and installed as per instructions. Someone was saying I may need to back it in more against buffer, as they had a similar issue with their AR9 where the bcg had enough space to move in upper and caused same dead trigger with him. Will try to adjust and see tonight and take it to indoor range tomorrow. Edited January 7, 2023 by Jrcnky Link to comment

With the upper/lower split, the buffer should be protruding slighting forward of the tube. If not, you’ll need another turn in on the buffer tube. Link to comment

Thanks. will try to get to pic and upload, but it looked like all the images I've seen. I'll start with making sure it doesn't need to just be turned in one more rotation. Literally right when I felt it hit the BCG during install I backed it out one, so I'm hoping that's all it is. Appreciate the quick reply. Was a real bummer as I was talking it up to a few buddies between stages and at end of match we gathered in the bay.....and nothing. Link to comment

Probably snapped it last night when I forgot to remove it when taking out the bcg weight. Link to comment
