| Can you tell me what new manufacture lowers do not have sear blocks? Specifically I ask as my Colt large pin preban sp1 will not work with a new Geissele trigger. I was going to buy another lower anyway, but want to make sure I get a brand that will work with their trigger. I believe Bushmasters never had the block, how about RRA or? TIA |
then disregard my first post because I thought you were talking about low/high shelf |
Colt was the *only* manufacturer to install the sear block. No other companies installed them as they were never mandated by law to do so in the first place. If I am not mistaken, the Geiselle trigger does not come in a large pin version as of yet. Also, SP1's never had a sear block. If your lower does have a block, then it is not an SP1 lower. |
I may be mistakenly identifying mine as a SP1. It is a sporter lightweight ser. 001XXX range. It definitely has a block stamped COLT. I have been on an email list with Geissele. They are going to come out with a large pin version, but the only word on a model for the Colts with the block is that there may be a non-adjustable model later. I want to build a match gun and use the lower with a dedicated .22 upper. Can you or someone explain the high shelf/low shelf thing? It's the first time I've heard this mentioned. |
