Ever do this before?  For some reason I cannot get the replacement hammer to work with the stock RRA trigger.  I followed what directions came with the gun.  That is: take out the old hammer, take the disconnector off the stock trigger,  buffer and buffer retainer, and selector switch.   After some 2 hrs of trying last night I cannot get the new hammer to work in the gun.   Will call the manf today, but thought perhaps someone has done this before.  I am thinking that this may not be dobale on a RRA stock trigger.....?
The gun shure looks great with a 29 " futted barrel hanging on it, but if it can't shoot not much use other than a flower pot.

If you have the 2-stage trigger, it's non-compatible with the Safety Harbor UL hammer...you'll need a standard semi trigger to properly interface with the new hammer.

Sluggo,  Thanks... hell for the money UL cannot tell me this in the first place?  Makes me wonder about the entire purchase........

Walter's a good guy...he just intended the UL to be used w/std trigger components.  I have a UL and it's great.  I put mine on a DPMS single-shot lower because I couldn't stand having the extra magwell...when I could have a different upper on it and be using it for something useful.

Sluggo,  I got the thing put together and may head for the range on Sunday.  Was interested on what sort of groups at what range you have got with yours...?

PS: BTW, mine is the UL 50, not Walter's  gun, but almost  the same. ( added just for clerification).
