[QUOTE="ARlife4me, post: 2328728, member: 105694"] The X shape is where the gas tube goes into the receiver. With the handguard off you can see it just above the barrel nut. Some gas tubes are straight and some have 1 or 2 bends in it. The bends are to clear the barrel nut and go straighter into the gas key. Those are usually on lowpro gas blocks. The straight tubes are more a2 gas block style or pic rail height gas blocks can be this way also. Not all are equal in design. Measure more in a straight line, but the added bends add length for more dwell time. Measuring the gas tube can be misleading? WC states 15.5" as you stated. Did the gb and gt come as 1 or purchased separately? If separately you might have a slr gas block (very good gas blocks). I have several AP receivers (AR15 and AR10 w/ other AP products), so I'm familiar with them. Site didn't give gas port size. I you have a bore scope, check alignment from inside the barrel. With the spring length being 11" it's a long (by 1.25"), but 25 coils is about right. Flat wire, multi-strand or spiral wound. Length can make a difference when compressed with flat giving a shorter oal compressed. Flat can be longer and have the same amount of coils, because it has more room too compress compared against multi-strand and spiral wound. [/QUOTE]
