GLOCK 20 or 21 Lower Parts Kit OEM LPK Gen 3 Not SF

Genuine Glock® 20 or 21 Lower Parts Kit OEM Gen 3 | G20 LPK G21 LPK from Marine Gun Builder. Frame is for illustration purposes only and not included.
 
Please note - if you are building a PF45 you will need the SF version of this kit. See store for availability.
 
Whether you choose MGB as your OEM Freedom parts provider or not, you must insure the kit you are buying includes:
 
(A) The latest G20 G21 Trigger from Glock - It is stamped 4256-3 on the cruciform. This is the one you want. The previous 2 versions sit too low in the frame causing a failure to return to battery problem.
 
(B) The ejector must be stamped 8196-2 for solid reliable ejection. Avoid buying a kit with the old 8196 ejector.
 
(C) The slide stop lever is different from all other models. A standard Glock Slide Stop will periodically jam you up. Insure the kit you buy has Glock SP05423 Slide Stop Lever and Spring. It will be stamped 5427-1 on the inside of the part.
 
Every Patriot who chooses MGB for their Freedom parts will receive a code shipped with their purchase for a Free Self-Paced Frame Assembly Online Course at Freedom Crew University.
