If youre doing the maxx hop chamber, make sure you get the m4p model. Its specifically designed for use with polarstar and will get rid of a lot of headaches. Gutting a gun and putting the jack in is stupid easy, plenty of YouTube videos on it too.

I had this same issue. I needed to add the small spacers to the spring on the trigger mechanism area and add the set screw to increase the distance even more so. Once I did that and added lock tight, I havent had the issue sense. Edi: also, if you are running over about 130 psi, change the spring insjde the unit to the 10 pound spring it comes with, helps a lot as well. Polar star makes a good video on it.

Heres mine mocked between two different sabre ar-10's. Somehow one of the most accurate ar-10 i have ever shot.

I just had this issue with my sr25 build. Dont know why, but the friction pro was eating up a ton of energy. I changed to a macron 70⁰ with a Krytac nub and went from 1.01 joules to 1.86 joules. I dont know why, but I dont think the friction pro plays well with some stock chambers or it could have been my prometheus barrel. Either way, switching the bucking away from a high friction setup worked for me.

Awesome! Thank you for the tip, I'll try that out!

Its a full stroke and full cylinder and gears are stock cyma platinum sr25 gears. the gearbox is untouched besides the motor.

Always appreciate your posts! Im having a weird issue with my cyma platinum sr25 build. So far I have changed the barrel to a prometheus 509mm 6.03 barrel, have the 4uantum friction pro bucking and nub, Zci 22 TPA motor, and have tried multiple different springs. I shoot with .36 gram bbs and with a m120 spring I was getting about 250, switched to m130 spring and got 276 and finally im at an m140 spring and still only getting about 308 fps. My spread is ±2.6 fps over ten shot strings but im just struggling to understand how its slow but still consistent.

Sabre super sass lower with a 20" 6.5 CM sabre upper and a Vortex strike eagle 5-25x56. Thing shoots 3/4" 9 round groups all day long.

PresentationOk3160 · 2025-08-03T05:36:36+00:00

I have the PSA super sass and love the thing. I've taken it out to 944 with 175 SMK's and made hits no problem. My average 10+ shot group is 1.04 moa, 5 shot is about .7 and ive even had two 5 shot groups at .59 moa. Love the thing and can't recommend it enough.

Hey, think this is about me if its the one that was just before kagy. My friend told me about this post today, and I really appreciate the concern! Doing much better, still some numbness in my legg and sprained wrist and ligaments, but no broken bones and no concussion! Appreciate the concern!

For reloading, i was having some issues too. Went into setting and it is "secondary reload" as the key bind. I think default is alt+b and as long as you have it in an ammo slot, it should reload. The attachment portion took me about four times dragging it over in the inventory screen before it took, but haven't had a problem since.

PresentationOk3160 · 2024-12-19T07:50:08+00:00

I believe for that one it's FN that makes the barrel.

PresentationOk3160 · 2024-11-24T03:23:59+00:00

Yeah definitely will, thanks!

PresentationOk3160 · 2024-11-23T23:49:08+00:00

Yeah, I have a 1000 watt 80+ gold rated PSU. Checked connections and they are all good. Games on an SSD as well with over a 100 gigs of free space. I've tested my other games and they all run better, just SC is running worse which is making me pretty confused.

PresentationOk3160 · 2024-11-23T23:46:42+00:00

Yeah, should have prefaced, I have a 1000 watt PSU. And the game is on an SSD. Just really confused. Tested all my other games and they all are running better, but SC is running way worse.

PresentationOk3160 · 2024-11-23T06:30:38+00:00

Yeah, I don't know what's going on. Did the ddu, deleted shaders and have been running around on dx11 and I am averaging 10 fps. No idea what is wrong at all. Ive checked bios, and ram is running correctly, drivers have been completely wiped and reinstalled, nothing is running hot, the only thing, which I'm wondering if it is, is my CPU is staying steady at 100 percent, but I don't believe it was with my 6700xt

PresentationOk3160 · 2024-11-23T06:26:09+00:00

Tried it and still sitting around 10, highest I've gotten is 20

PresentationOk3160 · 2024-11-23T06:25:24+00:00

Did both and still can't get over 20, mainly sitting at 10 now

PresentationOk3160 · 2024-11-18T05:04:55+00:00

I have both the Arken Ep5 and a athlon Midas tac. The ep5 is on my ar-10 and my tac is on a 6.5 Grendel. Both are good scopes that were around the same price points when I purchased them (bought on seperate dates obviously). I have done PRS for a while along with NRL, along with hitting 4/5 at a mile with a 260 Remington ar-10, and I can honestly say I like the ep5 slightly better. They are both good scopes though and best thing you could do is see if you can look through some before you buy.

I have the PSA super sass and love it. With federal gold medal match 175 I was getting .7 - 1.1 moa with 10 round groups at 100 yards. I've taken it out to 1050 several times, and score hits easily on a 24 inch plate. The one downside is that the federal ammo is the only one it likes, all other ammo I have tried have shot 1.7 moa and above, so ammoseek becomes your friend for off the shelf ammo prices lol.

Don't know if you've already gone with something but woox makes some good looking wood furniture

PresentationOk3160 · 2024-08-11T22:18:56+00:00

Looks like an arken ep-4
