I didn't see a topic for Other Caliber Lowers, so I apologize if this doesn't belong here.
Are the mag well drop-in conversion kits for converting a standard AR to a 9mm reliable?
I have a standard lower that already is an SBR lower and the price is obviously more attractive to temporarily convert it - but is it really that simple? I know the best answer is to just get a dedicated 9mm lower and another tax stamp, but I'd like to avoid all of that AND a new upper if possible.
Some magwell adapters may need to be tweaked for better performance. The Hahn was the go to some time back. For me it was nothing but a headache, be it factory Colt or aftermarket mags. On other forums you'll read of more issues with the magwell conversions than dedicated units.
Mags play a major part of smooth operation. To date the best performing 9mm AR's i've owned were the early Olympic arms (sten mag with mag well block) and dedicated Glock lowers.
I was going to SBR a DDLES (Now QC10) but decided to run a KAK set up, keeping it as a pistol. It's much easier to travel with and uses same mags as the carry guns.
or the altered sten mags from Oly.Quote:

This is not just my opinion. Colt on multiple occasions tried to buy rights to make Oly design before and after designing their own.
I have an old school Colt conversion that installs from the bottom of the mag well that works very well with certain mags. I maybe selling it as it's in a SBR that I usually only shoot my 16" upper on so it maybe be going a a dedicated lower of it's own soon.
