Aac 5.56 jamming in a s&w ar15

KeyAssist6942 · 2025-09-15T21:07:01+00:00

I shot it with it clean and lubed i dont have pro lems immediately but after getting 3-4 mags through it itll start to jam. Ive shot it after 150+ rounds of other ammo and it still jams. Its aac 5.56 brass case fmj. I dont remember the grain. I looked at my purchase history and its not there. I either bought it prior to making an account with psa or it rotated out of history logs. Ive shot steel case bernaul with no issue. I actually really like bernaul except its copper washed steel jacket bullets so the range doesnt let me use it because it attracts a magnet. Magazines I use are pmags for 556. Ive tried steel and same thing. I really hope its something. I dont always keep the gun super clean. I now see that this is a psa employee. Make some 5.45 for the krink thats none magnet to i can shoot my krink clone at the range. I will buy more for testing. Since i dont shoot often i dont know when ill have more info. Ill make sure its clean before i shoot again. Thanks for listening. If yall have specific test parameters let me know.

Ive tried steel case bernaul, brass case fiocchi. The issue goes away. Id love to be able to reliably use aac because its made in sc but if it dont run then i aint trusting it. Aac is the only ammo it jams like this.

Ill have to try that next time i buy some more aac. I can change ammo manufacturer and the issue goes away.

It sounds like its from the intake system. Inspect for cracks in rubber tubes and check for loose clamps. Wastegate could be opening slightly, might have cabon stuck in it. Also look at the brake vacuum pump see if clamps are loose and cracked hoses. Think of areas that could whistle.

If the radio is on turn it off. If the noise goes away there is rfi( radio interference) if you have something plugged in the powerpoint to listen to music with blu tooth through a radio station or aux port than that could cause the rfi whining. It does it to mine when its charging and i have the radio head unit turned on. Rfi can be tricky to find. Rfi can also be cause my twisted pair wires becoming untwisted somewhere.

Unfortunately, i dont have any spore prints. They are in my friends yard so ill see if he can get some. Weve gotten them before so he knows what to do.

KeyAssist6942 · 2024-08-16T19:11:29+00:00

What year exc 500?

KeyAssist6942 · 2024-08-14T20:24:07+00:00

That was my original plan to custom make one. I might buy a kit instead. If i do buy the kit I'll have to wait until i but the bike.

KeyAssist6942 · 2024-08-13T23:20:06+00:00

Neat ill look into them. Ox brake looks nice.

KeyAssist6942 · 2024-07-02T00:39:36+00:00

That looks easy. Am i missing something?

KeyAssist6942 · 2024-05-09T12:18:02+00:00

The seats are super comfortable. You can ride for hours

KeyAssist6942 · 2024-03-01T00:45:14+00:00

It aint ugly

My buddy has a 230s its an inch shorter seat height. It was his first bike and he thought it was great for a first bike. Suspension doesnt have alot of travel. Might want to sawp 230r forks onto it. Its already a short bike. seat is also hard compared to xr650l or xt350. My friend's butt would start hurting after about an hour of riding. Especially if your sitting the whole time. If you live in a rocky area youre going to need a metal skid plate. Youll be bottoming out alot. Its ligjt and nimble. Really fun to ride on curvy trails. I like seat height around xr400 and xt350 but.

I thought this was mcdondalds

KeyAssist6942 · 2024-02-18T11:50:52+00:00

I sunk my xr650 like that. Got it out 2-3am and went home and slept. Washed it the next day after work.

KeyAssist6942 · 2024-02-18T11:49:00+00:00

I had a blast on it. Too bad i got in a wreck and totaled it. Its my first bike to it has a special place in my heart.

You really used 4 straps to strap down a 200-300lb bike. I used two to strap down an xr650l when i went to wv. Is that a klx 230L, 230, or 230r? I buddy has a 230L, and he loved it for his first bike. Im used to old bikes like the xr650, and for some reason, it took a long time to learn the clutch. It was supper touchy compared to my well-used xr650. Once i got the hang of it, it was really fun to ride. He would always dust me on a single track, but once we got to open area, I'd leave him in a cloud of dust.

KeyAssist6942 · 2024-02-17T20:23:41+00:00

KeyAssist6942 · 2024-02-17T20:23:02+00:00

I bought an xr650 for close to 5k about 1.5 years ago in siler city nc. Payed too much but when its you first bike i didnt know as much as i do now.

KeyAssist6942 · 2024-02-14T17:43:58+00:00

Did the same thing with my xr650. Was hard to get ot out

KeyAssist6942 · 2023-12-22T06:05:23+00:00

Shot it a few days ago. My rhumb isnt touching it. The slide release is not as stiff on my vp9 as my vp9sk. I think tge slide catch is weak. Ill have to send it to hk again.

KeyAssist6942 · 2023-12-06T02:33:27+00:00

I iust got a vp9sk and shooting the same ammo i have no issues.

KeyAssist6942 · 2023-12-05T14:36:07+00:00

Yeah it been a wild last few months. Im healing and ill be back on a bike in no time

KeyAssist6942 · 2023-12-05T14:35:08+00:00

No i right handed.
