New AR9 builder (with FRT) with questions
I'm building my first AR9 (have built AR15's before) and plan to install a FlowFire LS device. I'm using an AR-15 lower so I will need a magazine well adapter for Glock magazines. Here's the issue...I would like to use a Foxtrot Mike upper and bolt, the reason being I don't have to modify the bolt. I DID learn on Blowback9.com that the FM bolt requires the extractor that is shaped like an "A" with an angled ramp on the backside (as opposed to extractor shaped like sideways "L")
Can anybody recommend a 9mm magazine adapter with such an extractor? If not, I'm thinking I can't use an FM bolt. I MUST be able to use a regular AR lower, and I hope to use Glock magazines as they are a lot more common. Thanks for ANY help!
PS: I would also be open to using a magazine such as an Exomag (fits into a stock AR15 lower and holds 9mm ammo) but am unsure of how the extractor works.
