Hi all.
When it comes to AR15's, I'm absolutely clueless. Partly cuz I can't own one... yet... I'm done some research, I'm searched, I've read ARF.com. But I dont really feel comfortable asking noob questions on that site and their search function is pretty useless since you can only search back to the last 30 days. The rest is all archived and cant be accessed into. So I'd appreciate any help you guys can give by answering some questions I have.
So I'm looking for an upper to go with my RRA LAR-15 lower. I've decided on the Standard A4 Stainless and the National Match A4 (comes stainless).
I can't really tell what the differences are:
Both use the same Wilson 1:8 barrel. Both are flattopped so you can add the NM carry handle to the A4's.
So what is the difference? Is the fit tighter on the National Match upper? Would I even notice it since I'm just getting a plain jane RRA lower?
Any advice to the LPK/trigger? I was thinking of getting the RRA 2 stage trigger. Would that be a good idea or should I look elsewhere.
Also, is it possible to use a free floating tube on a National Match upper? Steve at RRA told me that the FF tube is incompatible because of the DCM sleeves. How is that different from the standard sleeve?
Lastly, If I built the gun on the plain jane RRA lower, would there be any differences in accuracy between the standard stainless and the national match uppers?
My intent rite now is to build a full RRA AR15.
-------------------------------------------------------------------------
Somewhat unrelated. What is the gas block and what is its intended purpose? Also, if I built a M4gery, and I used the tactical mount provided by RRA, if I used an aimpoint can I still co-witness or would i have to use the flattop with a BUIS?
I appreciate any of your guys insight an help very much!
