Merle

I can help you out with this. I bought a PA10 stripped lower along with the PA10 specific carbine tube, buffer, and spring kit. The internal tube length is 7 3/4", the spring is 11", and the buffer is 3 1/4". I have only put 100 rounds through my rifle but it functioned without a hitch.

No problem! I've been in aircraft maintenance since joining in 1995.

Right on! I am glad to be back in AZ. I was born and raised here but left at 19 when I joined the USAF. I didn't dislike WA but that rain sure does get old when you work outside. Their gun laws were starting to get a little silly as well.

Looks great! I like Aero Precision stuff. Quality at a great price. I just wish they would make a slick side version of their M5 upper.

Just moved back to AZ after living out of state for 13.5 years in rainy western WA. One of the first things I did to commemorate the occasion was to put together a budget 308 AR using PSA receivers and BCG and a Ballistic Advantage 16" 308 barrel. I shot 100 rounds if Tula 308 through it and it ran great. I have quite a bit of experience assembling AR15s and this is my 2nd 308. Anyways, happy to be here.
