good item if you want to upgrade your m4 style lower, this is a lighter better tube that can be used for piston uppers plus it has a lower lip that will eliminate carrier tilt wear in the buffer tube.

this is a excellent trigger upgrade, if you have a pos milspec trigger and want a top tier trigger get this one and you will not regret it, i do strongly recommend during trigger install lube the pins, trigger components quite liberally with thick engine assembly grease or wheel bearing grease, so it functions like liquid ball bearings which will enhance function of trigger.

i do also recommend ordering a spring and pin kit for it as well, the only reason i say this is because when i ordered my first sd-e trigger i had a issue with the hammer spring not keeping hammer in ideal position, (middle of receiver) so i removed trigger, installed new pins, all new springs and problem was fixed, my issue was probably a fluke since i have never heard of this issue from anyone else, however it is always good to have a spare set of trigger pins and springs for this trigger group just in case you need them for any reason.

this is a good product, proper product for your a5 lower from Vltor, mine fits nice and tight on buffer tube, fit and finish is excellent and this allows a taller shooter to have a good length of pull.

good item to upgrade your ar-15 lower to a vltor a5 type or style, this is slightly longer than a milspec carbine buffer tube so you need to use vltor a5 buffer and rifle length spring to operate correctly.

these aero precision bcg are good quality units, have used one for at least a year no issues to date, i prefer the black version myself. my brother has the other version and both of them function fine dirty or clean in a 16 and a 20 inch upper, no fails at all in hot or cold weather.

works great when you need to remove upper and lower hand-guards on a 20 inch upper ar-15, this is a simple and cheap tool that allows a single person to remove the handguard by themselves, if you do not have this tool it may be difficult.

purchased this a few months back, along with the bolt carrier, stuck them in my bcm, functioned great smooth as silk in operation, ran about 800 rounds through the units and no abnormal wear, no problems so i am satisfied with units.

my cousin has this product, felt recoil is low and good, accuracy is excellent when using a variety of different bullet types and the upper does not get as hot as a carbine or mid-length gas system, so generally speaking accuracy is great, felt recoil is less compared to a 16 in barreled up and it runs cooler.

excellent product, my brother has this in his dpms ar-15 it is smooth as silk, weapon cycles and functions a bit better than the original bolt carrier group did finish is like glass, smooth and friction-less.
