Ordered – 09 Mar 2009
Mailed - 27 Oct 2009
Received – 03 Nov 2009
Kit Functional Check – 6-7 Nov 2009

After receiving the Del-Ton kit, I removed the preservative oils from everything (and I mean everything). Cleaned the barrel and performed a cartridge drop check after cleaning the chamber. The cartridge dropped free from the chamber when the barrel was tilled up (this is good).

During the disassembly, I did notice that the bolt has a ring/grove in the center (I have never seen this before) and the tail of the bolt had a distinct machine cut where it leads to the gas ring area (again, I have never seen this before).





Installed the LPK into a Double Star lower receiver, everything fit perfectly. I will say that the trigger pull is perhaps one of the best that I have experienced with standard parts. Pull was smooth and crisp.

At this point I lubricated everything using CLP and wiped the upper/lower with a lint free rag.

I then preformed the standard FCG function test and everything worked. The safety and disconnector worked as required. Next, to the range.

I arrived at the range with 630 rounds of PMC (Lot# 223A-081) ammunition. First, one round in the magazine, then fire. The case ejected smartly (about 10 feet) and the bolt locked to the rear. I repeated this 5 times to ensure that the basic operation of the rifle, safety/disconnector/ejection/bolt locking to rear was operating correctly.

Upon examination of the spent cartridges, I noticed that a dent occurred just at the bottle-neck of the cartridge (not a good place when reloading). Also, the cartridge head rim was rough to the touch where the extractor had grabbed the case during ejection. In addition, there was a semi-ring around the head of the cartridge from the chamber.







I then loaded a magazine with 2 rounds, the carbine functioned flawlessly with the second round being loaded and upon firing the bolt locked to the rear. I performed this 3 additional times just to ensure proper function.

Next was ten rounds loaded in the magazine (please note that I was using different magazines during this function test), all rounds fed/fired/ejected as normal.

I did this for a total of 50 rounds. No malfunctions occurred.

At this point I stopped and returned home to try and correct the problem with the dent on the cartridge. This had nothing to do with the function of the carbine as received. The carbine has function flawlessly to this point. I just wanted to try and prevent any damage to the spent cases for reloading.

I disassembled the BCG and removed the ejector spring and compared it to “spares” that I have. The difference between the ejector springs was nominal. At this time I decided to remove 3 coils from the ejector spring to reduce to force exerted on the shell casing as it is pulled from the chamber (hitting the barrel extension locking lugs was causing this problem).

I then inspected the extractor, using a magnifying glass, I noticed that the machine cut where the extractor grabs the case rim was very rough. So I decided to replace the extractor. The original extractor came with a black bumper and a four twist spring, however, I have never had a problem using the three twist spring and red/orange bumper.



I re-assembled the BCG using the new extractor (with three twist spring and red/orange bumper) and the cut ejector spring into the carbine and was ready for another day of shooting. I did not clean the carbine from the days firing as it was only 61 rounds.

At the range, I performed the same checks as the previous day. No malfunctions occurred and there were no damage to the cartridge cases as on the previous day. However, the ring around the spent case remained. I feel that this is do to a rough chamber. Overall, I am quite pleased. So I guess that the replacement of the rough extractor and cutting the ejector spring worked. The ejected distance did change to around eight feet instead of the original 10 feet. In the grand scheme of things this is irrelevant.

During this range session, I completed firing (569 rounds) the remaining ammunition with no malfunctions. The sights (removable carrying handle) were only off two clicks left and one click up (at 100 yards). I am quite pleased with the “overall” quality of the Del-Ton kit and would recommend it highly.

Overview: 630 rounds of ammunition fired, no malfunctions. Any replacement of parts was solely my decision and had no effect on the function of the Del-Ton Carbine.

Oh, one last thing…Thanks Del-Ton ]]> AR15 Discussion Forum Toten Kopf http://www.gunco.net/forums/f262/del-ton-m4-kit-review-depth-51153/ http://www.gunco.net/forums/f262/bcm-bolt-carriers-69-51-stripped-51145/ Sat, 07 Nov 2009 15:44:59 GMT BCM Bolt Carrier Auto M16


a fair deal on some bolt carriers. good quality stuff. the key is supposed to be fully chrome lined. my latest LMT carrier has no chrome in the key-- where the older ones do along with the colts.

i suspect LMT makes these BCMs along with DD's--although this is just scuttlebutt.

although i can't see that the lack of chrome in the key affects function in any way it is good to have the chromed lined keys in the old school way.:nono::loopeye: ]]> AR15 Discussion Forum j427x http://www.gunco.net/forums/f262/bcm-bolt-carriers-69-51-stripped-51145/ http://www.gunco.net/forums/f262/ar-7-62x39-questions-51024/ Mon, 02 Nov 2009 12:46:54 GMT Been looking at the 7.62x39 in an AR platform for a semi-auto deer carbine. There are a lot of really interesting AR variant cartridges out there I started looking and but when I saw the prices for barrels, uppers, mags, ect. :wow:.
So, I thought maybe the good old AK round that I already have a good supply of brass, bullets in both .308 and .311 and dies. Not to mention milsurp for plinking may be the way to go. My questions to any owners of this caliber in an AR is how much diffrence will barrel length play? I can find uppers in 16" but 20" may be a bit harder to come by. At any rate I would be interested in opinions or commentary on the best way to go for a Bambi blaster. ]]> AR15 Discussion Forum Wildgoose http://www.gunco.net/forums/f262/ar-7-62x39-questions-51024/ http://www.gunco.net/forums/f262/20-bbl-comparison-chrome-lined-h-bar-vs-ss-51019/ Sun, 01 Nov 2009 21:58:20 GMT I'm currently running a totally stock LMT Defender 2k: std. M4 lower, flat top upper w/M4 feed ramps, and 16" chrome lined bbl. it's a nice gun, no question there. after spending some time w/it, it's just too small for me. and, I'm also a full-size rifle guy anyways...so I've decided to swap in a 20" bbl.

like most AR owners (educated assumption), I only shoot it at the range or other private locations - but it certainly is my zombie apocalypse gun. I'll probably taking it out hunting one of these days too, so I want to make sure I'm totally comfortable w/my EBR buddy, and thankfully I'll only need the new bbl, gas tube, and handguard. but, I'm stuck on which bbl to order/install. my options, as I see them, are either:

- 20" H-Bar w/chrome lining
or
- 20" SS barrel

I dont know how much of this matters, but I intend to continue using BUIS as my main sighting system. scopes are nice, but I want to get exceptionally proficient w/the basics first. I'm also going to get railed handguards, either standard or rifle length, havent decided which. either way, the handguard will be free float.

I'm asking for suggestions w/reasoning, as well as opinions. I'm extremely grateful for any input you all can contribute! :) ]]> AR15 Discussion Forum masonwinston http://www.gunco.net/forums/f262/20-bbl-comparison-chrome-lined-h-bar-vs-ss-51019/ http://www.gunco.net/forums/f262/ar-buffer-tube-extension-51002/ Sat, 31 Oct 2009 06:37:13 GMT hey everyone,

it seems I'm a little bigger than the mil-spec GI, and I've kinda determined that my buttstock isnt long enough - I'd really like a 4"+ extention somehow. currently I've got the standard issue M4 6-position extend-o-stock, and shooting just isnt as comfortable as I think it could be.

any suggestions? ]]> AR15 Discussion Forum masonwinston http://www.gunco.net/forums/f262/ar-buffer-tube-extension-51002/ http://www.gunco.net/forums/f262/anbody-ever-have-problem-w-del-ton-50981/ Thu, 29 Oct 2009 20:56:27 GMT Would like to know about Del-ton and how good thier stuff is.
