Ok, my foamie just blew out of my LX, so is it necessary to have one on there or can I use it without one?

i don't use mine and I haven't noticed anything different

I believe the Foamy just makes the LX a little gentler on paint.

Well, i'll be using Rec-Sport this weekend so I guess it shouldn't be a problem.

You should be fine without the foamy.

Whenever I blow mine out I just Super Glue it back in place. But as you can see, it will work fine without it (but I want mine! I paid for it so I want to benefit from it!)

Ok, cool, I have another question and don't feel like making another thread. I was just dryfiring my RT Pro and I noticed it started to chuff around 1000psi or so, shouldn't it start to go at about 750 or so? I have LX and ULT.

At around 1000psi the regulator on the bottle starts to be restricted. It can not maintain the flow rate to supply a constant 800 - 850 psi that the mag regulator needs. If the mag regulator doesn't get a high enough constant input, then it can't fully recharge the chamber to the required operating pressure in adequate time after each shot. The result if the chamber isn't fully charged when you fire, the bolt can "chuff" due to insufficient force to push the bolt properly. The ULT exagerates the problem.

Edit: "At 100psi the reg...." changed to "At 1000psi the reg ..."

So if the problem lies in the tanks regulater, what companies reg will keep up with the RT?

All regulators suffer some from a restriction when the bottle pressure gets low. The regulator requires a differential pressure to operate properly. The larger the differential pressure from bottle to output, the better the flow. Some regulators are better than others, but many will function quite well as long as you maintain a bottle pressure at least 200psi higher than the output pressure. Its when you get below this 200psi threshold that you can starve the bottle/reg.

Degrease your bolt with a little acetone on a Q-tip. Put a tiny bit of Super Glue on the back of the foamie and stick it in place. I put one on a Lvl7 bolt for my Classic RT about 3 years ago and it's still there going strong.

Yea, I put another one on the other day and it blew out again at the field yesterday. I'm pretty sure it was because there was still a tiny bit of oil on the bolt.
