Lower receiver build questions.

[Troy]

Hi all,

I am planning to get a lower for my .308 upper budget build.  I am looking to get the lower from Tennessee Arms as I'm cheap and would like to know your opinions on them.  I have read some members posts of Tennessee lowers and will be trying to acquire one.  I have been searching for an Aero or other LR 308 compatible lower and all the places I see are out of stock and have been for some time.

I built this upper about 6 months ago.  I have been occasionally swapping off of my Cross Machine Tool 6.5 CM rifle lower (also built by me) and take this out occassionally.  Fully functional and now I want to give this upper it's own lower.

DPMS Lo profile upper.  Spinta Precision 18" SS 1:10 rifle gas barrel with a clamp on block, Spinta .308 melonited BCG, Surplus Ammo CH with Strike Industries Ext. latch,  15" unbranded free float keymod handguard, Precision Armament M4-72 .30 cal brake. Magpul MBUS pro sights and a cheap 1-4 optic with QD mount.  

Tennessee Arms has a sale on a preassembled lower as I already have the other parts to complete it.  Will be contacting them shortly as I have a dealer nearby who is willing to send the FFL to them.

     Even though the Upper works on another Lower , my thoughts are always to match the Upper & Lower Receivers with the same Manufacturer , because of possible Tolerance Stacking ,causing fitment issues, because there are no Spec'd standards on 308AR's .  Its your call .

Thanks for the info sir.
