My first build

[Buman]

Sorry for confusion. I am not well versed on all the names of the different pins and springs and stuff though I have used an M4 for the past 7 years.

When I bought the lower the parts kit that came from Plumbcrazy were all plastic. The plastic pin that stops the safety lever is the one that broke. I bought replacements pins that were metal and replaced that pin. However all other retaining pins are the original ones that came with the Plumbcrazy lower kit. Hope that clears it up a little bit.

I will get some pics up in a little while to should you how it looks. Thanks for feedback.

Just an observation, but it doesn't seem like the top portion of your RAS is installed properly. Make sure you have the retention 'legs' held by a screw on top of rail and have them under the barrel nut.

Yea, they've been using plastic LPKs...which is strange to me.

Here is a pic of the guts and where that pin was coming out of while shooting today.

Also thanks for feedback on rail system. I can't seem to get it to seat right on the top rail mount but the bottom fits well. Not sure what I am doing wrong but thats the fun of a first build I guess

Here's the instructions. Make sure the 'legs' of the clamp are below the barrel nut.

It's not very often you get to see new things tested on someone elses' dime.

Buman, could you keep track of how many rounds go through this? If nothing else, I am curious as to how long it survives, plastic LPK and all.

For $125 for the entire assembled lower, I am intrigued.

I will definately keep you posted. Going to try and put a few more rounds through today after work. See how those pins seat now that I have them put back into place.

Thanks for instructions I got it to seat in there properly now. It was too easy can't believe I had it messed up before. Oh well lesson learned!

Hello??? ARFCOM??? Is that you????

No one at TOS likes Plumcrazy. Well, maybe one guy. But now we have ours.

OP, let us know how it works. Don't use it for your home defense gun, though.
