Hello everyone I am an avid reader but rarely post on here. I recently finished an AR build and am curious as to which rail to start saving up for. I used this forum to help plan my build. I have a BCM CHF LWMidlength 16'' upper on a Spikes tactical stripped lower with a PSA LPK. I have a Magpul CTR stock, Magpul backup sight and a Magpul Handguard on it at the moment. I don't really want to go with a quad rail because I don't see myself ever needing to add a bunch of unneccesary gear and I think it would be uncomfortable to handle. The only think I can see me eventually wanting is maybe a light. I don't have any optic at the moment and probably won't for quite awhile until I master my trusty Iron sights. I want to let you know my setup and my possible future set up so you can best guide me to the correct rail im looking for. Right now I am looking at the Troy Alpha Rail or Troy Vtac Alpha. I like the fact that it is basically round with a rail on top. I am not sure which length would best fit my needs though. 11'', 13.8'', or 15''. 15'' seems like it would be to long and would have to sth with my front sight post, and i would rather keep that. So I guess my questions are: Are these good rails? Which length would be best? Are they pretty lightweight? I am more that open to suggestions on a different rail that would seem to fit my needs the most. Thanks in advance everybody.
