QQexDERA Posted March 11, 2013 Report Share Posted March 11, 2013 Is that with the stock barrel or an aftermarket one? Quote Link to post Share on other sites
PreacherMan Posted March 13, 2013 Report Share Posted March 13, 2013 I believe it's the stock barrel, just cut down and retapped. Quote Link to post Share on other sites
QQexDERA Posted March 13, 2013 Report Share Posted March 13, 2013 (edited) Carried out a bit of an experiment this morning, making up numerous combinations using the following parts:  2 x WE receivers (one old stock, one new) 3 x barrels (one standard WE, one Dytac, one Viper Tech with Tonic Airsoft WA to WE converter) 3 x Free-floating RIS systems (Dytac, G&P & Madbull)  Every single combination ended up with the same issue - the barrel appeared to be bending off to one side. There are two possibilities here. Either the thread on the nose of the receivers isn't square, so the RIS units are off at an angle, or the front of the receiver itself isn't entirely square, so when the barrel nut is tightened up the barrel is basically forced out of alignment. I'm hoping it's the later of the two, as I can do something about it (mount the receiver on a mandrel and true the face of it on the lathe)  Have a look at the lower two pics to see what I mean about truing the face of the upper receiver - http://ultimatereloader.com/2011/06/14/r-mpr-accurizing-the-upper-receiver-%E2%80%93-part-ii-milling-and-receiver-face-truing/ Edited March 13, 2013 by QQexDERA Quote Link to post Share on other sites
NonEx Posted March 13, 2013 Report Share Posted March 13, 2013 I'l tell you what it is. Â Check the pin holding in the dust cover. It may be a tad long and pushing on your RIS's. Â Had that one mine with a DD OX 7" raul. Quote Link to post Share on other sites
QQexDERA Posted March 13, 2013 Report Share Posted March 13, 2013 (edited) I removed the entire ejection port cover assembly and rod before carrying out my little tests, so it was one less variable that could affect the outcome - so as it wasn't there, it couldnt be the cause of the problem. Remember, that the receiver only has to be a fraction of a millimetre out at the face to make a noticeable difference at the end of the barrel.

NonEx Posted March 13, 2013 Report Share Posted March 13, 2013 Ah, OK! Â Sorry my comment above, came off as a little "Mr Know It All", sorry about that, was meant as a tip, wrote it wrong. Sorry it wasn't the solution Parts which are off-spec or crooked suck! Quote Link to post Share on other sites
QQexDERA Posted March 13, 2013 Report Share Posted March 13, 2013 It didn't come across as that - so certainly no need for an apology! I've ordered some 30mm diameter EN1A bright steel to machine down to make a mandrel to mount the receiver on in order to true the face of it. Quote Link to post Share on other sites
Wild_XIII Posted March 19, 2013 Report Share Posted March 19, 2013 (edited) Hey guys, I've recently picked one of these up. One thing for sure is that I need a NPAS as it's currently running at 430 FPS! I was wondering where the best place in the UK for spares is? The gun is second hand and could really do with a new bolt catch, possible even a new lower receiver. Â EDIT: forget that, I'm just useless at Google obviously! I just found a place!

QQexDERA Posted March 19, 2013 Report Share Posted March 19, 2013 Milspec solutions are good guys to deal with. TacticalQuartermaster can supply most parts as well. Quote Link to post Share on other sites

I don't have the ability to do this, sadly- and the fact my upper and rail are a one piece VIS setup doesn't help. Quote Link to post Share on other sites
QQexDERA Posted March 19, 2013 Report Share Posted March 19, 2013 (edited) Dytac VIS I assume? Must admit, not much impressed with Dytac kit personally, had all kinds of problems with their products. Edited March 19, 2013 by QQexDERA Quote Link to post Share on other sites
PreacherMan Posted March 19, 2013 Report Share Posted March 19, 2013 Unsure actually. I think the rail isn't Dytac, as it's permanently epoxied onto the upper receiver by the previous owner. It may be Dytac, though. Quote Link to post Share on other sites
QQexDERA Posted March 20, 2013 Report Share Posted March 20, 2013 Be interested to see a pic of that. The only (non real-steel) one piece setups i've seen so far are Dytac. Quote Link to post Share on other sites
PreacherMan Posted March 20, 2013 Report Share Posted March 20, 2013 Here's the only decent picture I've taken of it so far, if anything is identifiable from that Quote Link to post Share on other sites
QQexDERA Posted March 20, 2013 Report Share Posted March 20, 2013 Yeah, Dytac VIS 2 Midlength I reckon. Nice looking setup there! Quote Link to post Share on other sites
PreacherMan Posted March 20, 2013 Report Share Posted March 20, 2013 Thanks! Works very well, the barrel being off slightly is the only crux. Any way, you think, to face it without a lathe? Quote Link to post Share on other sites
QQexDERA Posted March 20, 2013 Report Share Posted March 20, 2013 Good question that. Will have a think about it! Quote Link to post Share on other sites
Piston Head Posted March 22, 2013 Report Share Posted March 22, 2013 (edited) I'm really impressed with my WE M16A3 so far and im looking forward putting a G&P M5 RAS on it to make a M16A4 MWS like replica. The problem is i'm used to rather short assoult rifles like the AUG with a 2 point sling and i really want to get a tactical/practical useable sling for my M16. At first i was looking at original usmc 3 point slings but i couldn't find them in OD and then i came across the Mamba's from Specter. They seem to be a decent alternative but i have troubles finding retailers in europe.  Are there any suggestions for a decent quality 3 point sling?  I't looks like the "wrap around the RAS" versions are a good choice when it comes to stealth because you don't have metal on metal making noise or am i wrong..? Wich one do you prefer? Is the "bungee part" a nice addon and has it any negative effects on aiming in motion?  Thank you for your patience Edited March 22, 2013 by Piston Head Quote Link to post Share on other sites
QQexDERA Posted March 22, 2013 Report Share Posted March 22, 2013 3 point slings are the work of the devil, they get hung up on the gun and your gear. You're far better off with a 2 point sling from the likes of Blue Force Gear (Vickers sling), VTAC (Viking Tactics) or EMDOM USA. Â @Preacherman - had a bit of an idea, but will have to trial it first. I'm thinking along the lines of http://www.brownells.com/gunsmith-tools-supplies/rifle-tools/receiver-tools/ar-15-m16-upper-receiver-lapping-tool-prod20220.aspx - but with one hell of an extension on it! 1 Quote Link to post Share on other sites
PreacherMan Posted March 23, 2013 Report Share Posted March 23, 2013 (edited) My god, that's clever! How do you think that could be extended?EDIT-Â http://www.amazon.com/Bosch-Daredevil-DSBE1012-12-Inch-Extension/dp/B002BYOWKMHa! 12 inch extender, would clear my 10in VIS with room to spare. I have a DeWalt 9V drill somewhere downstairs. Thanks mate. This fixes my only real problem with my WE M4. Local automotive shop carries lapping compound, just means two more orders.Anyhow- seconded on the 2 point sling thing. I run a Magpul MS2 with zero issues, my mate's ran one on a battle rifle for a while. Edited March 23, 2013 by PreacherMan Quote Link to post Share on other sites
Piston Head Posted March 23, 2013 Report Share Posted March 23, 2013 @QQexDERA - thank's, that makes it easier finding a retailer Quote Link to post Share on other sites
PreacherMan Posted March 24, 2013 Report Share Posted March 24, 2013 http://www.exploreproducts.com/wheeler-delta-series-ar15-receiver-lapping-tool-156757.htmTwenty two bucks! Ships to Canada, too, and has a flex shaft. Means I don't need to get that, OR lapping compound.Seems like it may take a little while though, hopefully the Dytac receiver isn't too tight to get it through.

Wild_XIII Posted March 28, 2013 Report Share Posted March 28, 2013 Hey guys, I have a question about the bolt catch. Is there anyway to make it more reliable? I know that I need to get a new one as the current one has worn away far too much to catch, but is there a way to either reduce the wear or stop it? I'm still looking into getting one of these but I'm just looking into ways to keep the parts going longer. Quote Link to post Share on other sites
Danke Posted March 28, 2013 Report Share Posted March 28, 2013 Some local folks mentioned washers in the buffer tube to restrict the stroke of the bolt. Â So stock it recoils a few mm past the catch and then flies forward till caught; less travel means it has less momentum when it reaches the catch so less chance of overriding it. Â You don't need much. Quote Link to post Share on other sites
Wild_XIII Posted March 28, 2013 Report Share Posted March 28, 2013 Thanks for the info. I'll look into what I can do. Quote Link to post Share on other sites
