hey everyone... ive been considering a new generation rifle, and well, none of them really offer anything the AR15 doesnt, sure, some offer a quick change barrel but at the loss of zero... whats the point of that if you have to re-zero your sights... still, AR15 winds out in my opinion, so ive decided to build one..
for the lower receiver, theres not going to be anything special, i may put an extended bolt release on it, but im about 50/50 on that... one thing i will do is install some means for quicker take-down, such as a push button pin, or an extended captive pin thats easier to grab and pull
the upper receiver is going to be different from most AR15 uppers, its going to be closer to that of the rock river PDS rifle... the recoil spring will be moved, the top charging handle will be removed, i will purchase a forward assistless upper receiver, a smooth stripped carrier, and i will install a side charging handle, probably on the right side of the receiver, and this will function as a forward assist as well, ive though about a left side folding charging handle, but its just simpler to go this way, less moving parts, simpler, lighter...
since i will no longer be using the top charging handle, i will replace the head of the top charging handle with a captive guide rod/recoil spring assembly that will mate with the newly designed key on top of the bolt carrier.. the bolt carrier of which will be removed behind the firing pin area...
since i have a new recoil spring location, a shorter carrier, and side charging, i will be able to remove the buffer tube entirely, and install a folding stock adapter, which will allow me to use any AR15 stock as a side-folder as well....
ive never seen a reliability advantage towards piston systems, but im about 50/50 on whether or not i want to install a short-stroke piston system, if i do itll be for quicker cleaning, only having to open the front of the gas block, remove the piston, and run a small bore cleaner through it, and with the recoil spring directly behind the piston itll take care of the carrier tilt issues as well...
so besides all of that, ill have a 16" length barrel, havent decided on weight yet, chrome lined, probably 1 in 7" twist, top rail all the way across with flip up front and rear iron sight, more ergonomic grip, and an angled forward grip and thatll all be about it... probably a regular birdcage flash suppressor and magpul stock..
the idea of moving the recoil spring and shortening the carrier isnt new, but does require moving the charging handle, the rock river PDS has a short recoil piston and moved the charging handle to the gas tube, im simply mounting the charging handle directly to the carrier itself...
something i could do if i wanted to keep the top charging setup would be to use an AR18 type recoil spring assembly but the side charging will let me eliminate the forward assist as well, so it kills a few birds with one stone going that way
so, what do y'all think?
