 Well I broke my gas plug...

You may remember me from such threads as "What's wrong with this picture?" where I wore out the flash hider. Well after almost 3 years and god knows how many rounds the pin that holds my gas plug in broke, so now all that is holding the gas plug in is the carbon fouling. But the gun still works I noticed the pin on the floor in the middle of a Tiger Valley mini-class, not knowing what it was I continued to shoot the class (it looked like a stock in, and my stock was working), I only figured out what it was when it hit me as I was going to sleep.

So I'm going to call today, and see if I can get a replacement, as I am hoping to make the Pat Rogers class in Texas, and I would prefer to bring my usual POF upper.

I will post pictures when I have to chance to take them tomorrow.

Don't forget to post a picture of the new one and let us know how the CS is doing.

Mailed it out today. But I'm not expecting that the package is processing until the week after SHOT show.

I also sent a check, and ordered a parts kit. Now that I know that this is a potential wear item, it might be best to have another one.

Great point/pic.

How many rounds would you say that plug had on it?

Do you clean the piston system each time you clean the rifle? I'm only asking because I hear different things about cleaning from different piston owners/brands.

The gas plug had about 15,000 rounds on it.

I clean it every case or so. Sometimes more, sometimes less, it depends on what I am planning to use the rifle for next time.

Thanks.

The LWRC piston system seems a little easier to clean/assemble/figure out once you get over the massive amount of compression you need to put on the recoil spring to get it all back together (which doesn't seem right).

That plug on my POF is a PITA insofar as getting it off and on while figuring out where it should be when 'ready' as mine must be a Gen 1 and is unmarked.

Yeah the LWRC piston is easier to get out, but that spring adds it's own wear item. IIRC Pat Rogers was suggesting a replacement schedule of every 5,000 to 10,000 rounds. So there are trade offs, also the POF doesn't require the rail to be removed to access the piston.

Good point, as it's more work and fitting it back on is a pain even w/just the side rail covers.

Sometimes, I miss DI rifles because I can clean them w/my eyes closed.

No picture of the new one yet. But I got the gas plug in Friday the 29th, couldn't take it to the range that weekend since I was at a class, so it made it to the range this weekend. No issues, through it appears that they changed the coating method.

I also ordered a set of upper piston parts, so I have spares in case something breaks at a class. Might have to order a bolt carrier too one of these days.

Well a few more hundred rounds to test the gun with before I take it to Pat Rogers Carbine Operators in March.
