dpete Posted March 1, 2015 Report Share Posted March 1, 2015 Yes I know its missing a few pieces but at least I know the rest is on the way from Aero Precision. The heart of the rifle will be an Aero 308 lower, the M5E1 upper receiver/keymod handguard, their 308 NiB BCG, and 308 LPK. I hope to see the rest of the parts come in this next week. The barrel is the 18.5", .308 AR, Light Weight, 1X10 twist, chrome lined, match quality, by Criterion sold by Fulton Armory, with a Bully Brake from Overkill Customs on the end. 20 round Pmags and 5 round ASCs for hunting. I've been reading as much as I can find in preparation for building this rifle and after reading about checking headspace I have a question about checking it on this barrel. On Fulton Armory's site they call the chamber a hybrid. "Our Hybrid Match Chamber allows use of .308 Win & 7.62x51 mm NATO Calibers" http://www.fulton-armory.com/barrelfatitan185lwcm1x10750gasblockchrome-lined.aspx I know both .308 and 7.62 headspace guages exist. Which one would give an accurate indication of proper headspace? I only intend on using commecial brass/bullet handloads in it and not wanting to risk anything I thought I'de ask those with way more knowledge than I have.

george_995 Posted March 1, 2015 Report Share Posted March 1, 2015 (edited) Good start, looking forward to the finished gun. What are you planning on for trigger and glass? Edited March 1, 2015 by george_995 Quote Link to comment Share on other sites More sharing options...
dpete Posted March 1, 2015 Author Report Share Posted March 1, 2015 For now I'm staying with the trigger in Aero's LPK. I've read reports its better than the usual milspec triggers in ARs, which I have gotten used to. I already have a Nikon 3X9X50 scope waiting for its new home to be finished. Hopefully I can get an answer on headspacing the bolt to the barrel. Quote Link to comment Share on other sites More sharing options...

Now to see if a local gunsmith can do it once the rifle is finished. Quote Link to comment Share on other sites More sharing options...

I know there are better after market triggers but I am happy with my stock trigger. I have a 6.8 with a mil spec trigger and my son has a dpms 308 as well. Aero trigger is better on these three rifles by far. Looking forward in seeing yours put together. Quote Link to comment Share on other sites More sharing options...
dpete Posted March 6, 2015 Author Report Share Posted March 6, 2015 Some more parts came in today and since I am still waiting for the lower and gas block to complete things I took some weights of the pieces I have. The Aero parts are noted. Weights so far: Barrel = 2# 8oz Criterion 18.5" lightweight profile from Fulton Armory Brake and washer = 4oz Bully Brake from Overkill Customs here in WI Upper & barrel nut = 1# 3oz 1st part of Aero enhanced upper combo 15" keymod handguard = 9 oz 2nd part of Aero enhanced upper combo BCG = 1# 6oz Aero NiB Stock, spring, buffer, & RE = 1# 3oz Pistol grip = 3oz LPK = 4oz Aero 308 LPK Total of these parts = 6# 12oz Right now I can't remember if the charge handle was in the upper when I weighed it so the total might be a tad heavier by a few ounces. Even if the lower and gas block amount to 2# total I'll be looking at around 9# total for the bare rifle. Add in about 1 1/2# for scope, mount, sling, and swivel rings it will be pushing 11# or so I think. How close am I? Quote Link to comment Share on other sites More sharing options...
dpete Posted March 20, 2015 Author Report Share Posted March 20, 2015 ITS FINALLY DONE! After waiting almost 3 weeks for Aero to get the lower and gas block back in stock they came in today and she is done. Total weight as seen here is 10lbs 2oz with an empty mag. Its bathed inside with CLP right now and I've worked the action by hand and ejected an empty shell and loaded a dummy round after it. Ejecting the empty and dummy went just fine. I had the bolt/chamber headspaced today and the gunsmith said he rarely sees chambers and bolts that well matched. As he put it a zero, not + or - anything. So far so good and now I wait for decent weather to get out and shoot it. In the meantime how much should I work the action by hand? Quote Link to comment Share on other sites More sharing options...
Bad Wolf Posted March 20, 2015 Report Share Posted March 20, 2015 (edited) Looks dang nice. I like those Enhanced Uppers, just don't care for the price. Edited March 20, 2015 by Bad Wolf Quote Link to comment Share on other sites More sharing options...
dpete Posted March 20, 2015 Author Report Share Posted March 20, 2015 Thanks! I hesitated about the price too at first, until I priced out what the separate similar parts would cost. I think it came out to allowing about $100 or so for the 15" hand guard I used. The simpler barrel nut and rock solid connection between the hand guard and upper sold it for me.

smith0791 Posted March 21, 2015 Report Share Posted March 21, 2015 Looking good! I just completed my aero build with that same fulton barrel! I can tell you that you are going to absolutely love it. the thing is dang freakin accurate its scary Quote Link to comment Share on other sites More sharing options...
98Z5V Posted March 21, 2015 Report Share Posted March 21, 2015 In the meantime how much should I work the action by hand? I wouldn't even bother - just lube it up real well and shoot a few hundred through it. It'll be good after that. Probably won't even take that much.
