Need some help guys. I would like to keep the back up sights on the gun. Which mount do I need? Will the LT 104 clear the rear buis? Should I get the LT 139 and just move it forward a bit? Thank you in advance, this is my first LT mount purchase (have some other goodies though)

Quoted:
With an LT104, you'll have plenty of clearance. Hi Mark, Not trying to be a wise guy as I am sure you know better than I do, but I seem to remember when I order the LT-104 that the LaRue rep on the other end mentioned that it will clear my TROY BUIS but not if it was a MAGPUL BUIS – is that correct? I know the Butler Creek covers reduced the clearance. |
| There is still a chance that it may work as I cannot be 100% sure of what I quoted to Mark since it was over a year ago the conversation took place. The unfortunate thing is MAGPUL does not give any actual stats on their BUIS, just general statements in their “SPEC” page. There are unfortunately so many possible combinations possible out there since you are talking about three items (BUIS, mount, and scope) that it is almost impossible to know unless someone has that exact combo. I will be willing to measure the TROY BUIS, but unfortunately I no longer have the LT-104 since I traded it for a LT-158, and of course I don’t have a TAC30. |
| It’s a reasonable way to go, might want to post the same request on the OPTICs page. As for the RISR, I don’t have that, but my understanding is that it has more to do with cheek weld and the charging handle and I don’t see how that would affect the fit between the BUIS/LT-104/TAC30. |

Was not thinking the RISR would interfere with the BUIS/Mount/Optic, but was not sure if having the RISR would necessitate a higher mount. If it is not glaringly obvious, this is my first magnified optic, and I appreciate all the knowledge provided by folks on this site, like jlow and all the other great folks here. Alden

OK. Have you seen the other thread here on the RISR? It seems that it is too high for a regular M4 which I think is what you have with a regular flat top. My guess is that it might be too high for an optic too but not sure. Works for the OBR because I think their rail is higher? http://www.ar15.com/forums/topic.html?b=2&f=219&t=198930 |
