What are the specific M1S problems?

I'll check.
I have the CAR spring & buffer & I think I'm running IN the gun:
CAR spring & the A2 buffer.
I have an AAC 762SD can also.
I don't think it holds open on last shot w/subs but not sure.
I can shoot supersonics w/it & it doesn't seem to "slam" anything.
I almost always shoot subs but carry a 20 round mag of 125g Nos BT in case I see a doe I want while hog hunting.

Pitt300, did you have the port placed in the pistol position? I also have the same can waiting on my form. Any tips or things to watch out for using the can?

I looked at model1 site and did not see the 300 lite spring ,was that a special request thru paul? with the stock gas block everything cycled fine but I could not leave well enough alone and went and put a 3 position (low/full/off) gas block on it and it started having cycling issues , may just take it off and go with the stock block, just tinkering ,,,,,,,still

Carbine Position!

Paul has a "special" 300 Whisper package made up that you have to ask for.

I'm running just the stock CAR spring.
