Man you guys are a rough crowd.....lol... Iam running the Spikes st-t2 with a JP performance carbine spring in a 14.5 Spikes/FN Mid length gas system. Shoots really smooth and no BOINGGGGGGG also running a Dynacomp with it. Runs with everything I have fed it.. its my go too setup for a carbine gas system also.... deffinetly seems to smooth out the cycling IMO.... hope this helps a bit....

That is also a reason I went with the ST-T2, no more boinggggg. Mine is in a nj castrated M&P-Orc. Cycles light and heavy loads no problems, runs very smooth, its a must-have.

Have you run it in the winter/cold with something other than m193 spec ammo?

Yes I have dunked in water.. in snow and mud and its always run... even when the frog lube gets really thick in the cold.....

What's the difference in the JP spring and a stock mil-spec spring?

The JP spring is an extra power spring that uses a flat wire spring that is polished compared to the stock run of the mill carbine springs... I've used them on all my ar's and have never had an issue... the bonus is it doesn't have that BOINGGGGGGG sound... and its much smoother in cycling the bolt.. hope this helps...

That noise is annoying. My sig's factory spring is quiet. My s&w not so much.

Yea that sound is so annoying. I hear the spring compressing and decompressing.

 

Any one know the weight of mil-spec buffer from stag? I can't find it anywhere

Ive never paid attention to the sound of the spring. You guys are easy to distract lol.

I received the buffer on Thurs. Planning to hit the range up tom to test it out. I'll report back.

Cool keep us updated....

Anyone try the PWS buffers?

I didn't go yesterday. I'll try and get there sometime this week. Possibly Thursday.

Do me a favor. Before you put it in. Wth the lower off and no spring in the tube. Have the tube 90 degrees up and drop the buffer down the tube. Then tilt upside down. Do that ten times and tell me if the buffer slides top to bottom every time and never catches inside so you'd have to give it a little shake to fall. Thanks.

Mine slides fine, no shaking needed

Hey. Sorry I took so long. It never caught and slid every time.

 

I finally got to the range this weekend. Fired 150 rounds of IMI855, PMC Bronze, and reloaded .223. Bolt stayed open after last round with all ammo, until after around 100 rounds where it wouldn't stay open with the weaker PMC ammo. It still locked back with other ammo. Took out bolt, lubed it up, and again it did lock back with every ammo including the PMC. Thanks everyone for your advice. Lesson learned? Make sure the bolt is sufficiently lubed, especially when shooting weaker ammo.

running wolf ammo, bolt locks back on an empty mag each and every time...unfortunately it appears my rifle doesn't like stronger ammo - but that's a different issue.

One thing I forgot to mention. On last shot, when I went to reload and tilted the rifle with he muzzle facing upwards, the charging handle would slide down a little bit. I've never experienced this before. Can anyone tell me why it's doing this?

Was it fully forward and latched?

 

If not, it will slide.

Brand new CH?   If the latch on the ch isnt working correctly the handle will slide around all willy nilly.

No it wasn't. I don't know why though. Any other time I've run out of ammo in a mag, and the bolt locks back, the CH would always latch.

I was able to just push it in and it would latch, but what do you think is the reason it wasn't latched after last round fired from mag?

Only think I can think of is it got caught on something or is a defective handle

BCM Mod 4.

That sucks.

Try to duplicate it. Is there a lot of tension on the spring at the lever?

Yes I would push it all the way forward and the try to pull it back without releasing the latch and see if it comes back

I'll check that tonight.

If I push the CH back in, it does latch. It just wont' latch when last shot is fired. If I tilt muzzle up to reload, the CH slides down. But it does latch and stay latched if I push it in.

Do you have enough lube on the CH and bcg that so there is minimal friction when firing? I can only think its the bcg moving back and knocking the handle out of position.
