I know it's been discussed before but for the record...

I have a lower that is either already at, or will soon be at my FFL. Shortly thereafter it will be off to be engraved.

I already bought some parts as well, and I am asking for stuff for Christmas as well... hence the thread.

Before I go into what all I am building is it true or not true that 10.3 or 10.5 builds can be more finickey than a longer build such as an 11.5 or a 12.5?

From what I recall...the whole dwell time thing matters a lot.... as does the correct porting on the barrel. And will an adjustable gas block help the gun run more smoothly when talking about such issues?

----

Now for what I am building....

*CMT non ambi lower (already bought, just have to pick it up)
*probably a CMT slick side upper (depends on Santa Claus)
*CMC 3.5lb single stage flat trigger (bought already)
*Rainier Phosphate BCG (bought already)
*SLR 10" Mlok solo lite handguard (depends on Santa)
*Probably a MFT minimalist stock (undecided)
*11.5" barrel (unknown yet)
*SLR adjustable gas block
*One of the griffin taper mounts so I can use my can on it (either the minimalist or the hammer comp so far)
*Griffin Snatch
*Probably an Aimpoint T2 with a lower 1/3 mount (probably the CMT mount)

Depends on how long the engraving process takes, but hopefully I will Form 1 soon.
