I used cmmg bcg and barrel and there mags in a standard ar15 upper and lower and it runs great, really impressive. also super 42 H2 buffer
you will need to verify the trigger assembly is compatible, there are several videos online that talks about milling down the metal because there isn't enough clearance. If its milled too far down, it'll just become a semi-auto and not assisted semi-auto
Negative, those states that limit everything else limited this.
Atrius states this selector is a drop-in fit for Mil-Spec AR-15 lowers in .223/5.56/.300 BLK with no other modifications needed, so it should work if your LWRC rifle has a standard Mil-Spec lower and trigger setup, but compatibility with a non-Mil-Spec LWRC trigger is not specifically addressed.
No, this Atrius Super Selector is designed for Mil-Spec AR-15 platform rifles only, not the AR-10.
I am not sure. The listing only confirms compatibility with Mil-Spec AR-15 rifles chambered in .223, 5.56, or .300 BLK, and does not address the ATI Omni Alpha Maxx pistol specifically.
This selector is designed for Mil-Spec AR-15s chambered in .223, 5.56, or .300 BLK, and .22 LR platforms like the POF P-SG-22 are not listed as compatible calibers, so I am not sure it will work in that firearm even with the RA-140 trigger installed.
Yes, since the Atrius Super Selector is designed to drop into any Mil-Spec AR-15 lower chambered in 5.56, it should fit a SIG M400 Tread in 5.56, including the 11.5 inch barrel version, as barrel length does not affect the selector's fitment.
No, this standard Atrius Super Selector is not compatible with the Geissele SSA. You would need the Atrius Development G-Lever Ambidextrous Forced Reset Selector, which is specifically designed for compatibility with the Geissele SSA, SSA-E, and G2S triggers.
The RA-140 is a favorite according to ATRIUS compatibility guide. So you would be good there. However the M&P-15 is considered a “high shelf”
Lower. May cause some problems. Typically you would need “low shelf”
