Hello everyone, I am looking for some technical knowledge on how to relocate a gas block and see if my idea is at least plausible. I am contemplating purchasing the troy carbine from dicks sporting goods, it is just such a sweet deal. It has the barrel, twist, finish, rails, grip, sights, everything I want in an AR15 besides a midlength gas system. The alpha rail that comes with it is a 13" with the folding sight, and it is listed as incompatible with midlength systems.
First question, is does anyone have experience with this rail, and will it work with a midlength system as long as the build in folding front sight is not folded down? Second Question since it has a carbine length gas system to begin with, is it possible to redrill the barrel for a mid length system? I have though about using two spikes micro gas blocks, using the first one as a "restrictor" and purposefully misaligning the gas hole in the micro gas block, so that a solid portion of the block covers the original gas hole, and then either drilling out the hole that accepts the gas tube in the first micro block so that the gas tube can run through the block rather than being pinned into half of it. Then drilling out the barrel to the proper place and size of a mid length gas hole and using the second micro gas block as it was intended. Or, would it be easier to use a misalignned micro gas block to cover up the original gas port, and grind it down until it fit under the gas tube? For both projects, Id also use a melonited mid length gas tube, and budget would be about 100 after the two blocks and shipping. I can do all the work myself on a mill, any input would be extremely helpful. Is it plausible to do this myself, or is there any other way to convert a carbine gas system to a midlength gas system and how much would it cost? |
| You can have it done..... but the cost to do it would probably make the rifle overly expensive. 1. Just get a Midlength upper from someone and sell your upper on the Equipment exchange. or 2. Don't get too rapped around the axle about midlength... use it and just put the rail you want on it. done and done |
