Idahunt Posted August 10, 2015 Report Share Posted August 10, 2015 (edited) All, I've combed Google and have not seen what I think is a definitive answer. I'm considering getting a complete SR25 upper, what lowers are compatible? It looks like matrix and AR10a are contenders. Does anyone know for sure? Any interesting differences/nuances? Thanks for any info or point to a link I may have missed. Edited August 10, 2015 by Idahunt Quote Link to comment Share on other sites More sharing options...
guruofhotrod Posted August 10, 2015 Report Share Posted August 10, 2015 (edited) Looks like Genesis 80% lower: http://genesiscnc.com/ and possibly Mega, - The Genesis website lists LMT,La Rue, and Les Baer as being compatible with their lower in addition to Armalite and KAC - the do mention specifying a .281" pin size on their upper for LMT and KAC lower compatibility Edited August 10, 2015 by guruofhotrod Quote Link to comment Share on other sites More sharing options...
Idahunt Posted August 10, 2015 Author Report Share Posted August 10, 2015 Thanks guru, I looked at the Genesis but I hope to avoid getting any finish machining done. I forgot about the pin issue .281 on the sr25 upper and .277 on the "other" lowers. Quote Link to comment Share on other sites More sharing options...
