I have wanted to build a PDW style SBR for a while now. Had intended on going with a 10.5" 5.56 barrel as 300 aac ammo is too expensive. Recently I have been reading up a little on dedicated pistol caliber AR Set-ups and am interested in exploring this option a little more.
I have primarily been looking at the PSA uppers and lowers. They offer two style in 9mm, Glock or Colt. Is there any advantages to one over the other? I don't own a Glock so don't have Glock mags around which I could see as a reason to go with a Glock style lower.
Also regarding the PSA offerings are the lowers compatible with other brands uppers or the other way around? The description does say it's designed to work PSA uppper/PSA Lower.
Apart from PSA, other companies I should look at?
Also, how about drop in 9mm conversion kits, do these generally work well? Any specific brand recommended?
The pistol caliber set up is attractive to me because of the price of ammo, able to effectively use shorter barrel, and quieter to shoot. I do have concerns about the effective range and accuracy. I know a rifle caliber will out perform a pistol cal, I would like to know by how wide of a margin.
What type of range / accuracy can one expect a 9mm SBR fired from a 8"-10" barrel? Obviously this is not a precision platform, and it depends on factors like barrel quality and ammo quality. But a ball park estimation of the platforms capabilities , for example is 2 MOA out to 200yrds possible?
