I need a brand new bolt to use with my new build. It's a Bushmaster barrel/extension in a CMT upper. I've heard that Colt bolts are very good if not the best, is this true? Any other type I should look for? for what it's worth, this bolt is going into my SHTF carbine so I would like something top notch. Another problem I have is that I need it by this weekend. Anyone know where I can get one, a place that has them in stock? |
|
Well I'm certain I'll piss off the Kool-Aid people but Bushy, RRA, LMT, they all make good bolts/carriers. I just bought 2 LMT M-16 bolts w carrier from Bravo Company and they are performing flawlessly. Do you just need the bolt or the carrier also? I had mine 2 days after I placed the order with Bravo...... |
|
pic and info here Where to buy no idea, are they needed? I never used them or those plastic/ rubber things that go in around the extractor. My AR's seldon see over 300 a day. |
The modified LMT bolt is certainly not a bargain at all, and maybe just another answer looking for a problem. The standard bolt design has held up well over the years. |
The enhanced bolts are the same as the "enhanced carriers". Theyre either chrome or nickle plated, which really provides no advantage except cleaning. Its so much easier anc cheaper to just take a standard LMT bolt and put new extractor springs in it. |
Check with Pete, he ships VERY fast as well. He's Pete-in-NH her on Arfcom. www.ar15sales.com/ Bolt carriers are here. Get an 'enhanced' RRA bolt and carrier (right about $100) 1-603-770-2281 You will not be disappointed. |
I don't use paypal so unless he has a way to accept credit cards, I would have to mail payment which would take too long. I only need the bolt, not the carrier. |
|
Brownells has DPMS bolts, assembled, for $49. Shows to be in stock. That's if you're in a hurry. You could always shop around for a nice one later and keep the DPMS as a spare. You are going to stock some spare parts since this is your SHTF rifle right?

I think you misunderstood my answer. Buy only premium Bolts Like Colt or Young & co. or Les Baer Bushy, DPMS & others do not properly test their bolts, No MP Inspection, No shot peening. A bolt failure is a very dangerous thing. Where to Purchase? CHeck the Equipment exchange, COlt bolts are listed for sale @ reasonable prices all the time. |
And that is what it's all about SHTF, life and death, why take chances, proven quality and proper testing You're in New Jersey, go to SARCO, they're bound to have a Colt bolt amongst all their "Stuff" If you need it asap Call Specialized Armament it wont be cheap but if you are willing to pay the price and shipping you can have it by the weekend, otherwise keep an eye on the EE |
| LMT is probably the best, but any Milspec bolt should be acceptible. My latest Ar15 was a DPMS AP4 which came with a chrome bolt, which is awesome looking and slick to clean but I have generic milspec bolt just in case. Supposidly, the chroming process they use doesn't make the bolt brittle like the Vietnam pre A1 M16s....I have heard less than satisfactory results from the titanium bolts, so I wouldnt advocate thier use. I think its a good idea to keep an extra bolt assembly around incase of failure. Its a quick and easy way to get you back into the fight...If mine didnt come with chrome I wouldnt have bought it, but it seems to work and provided I dont slam it onto the pavement, I suspect that it will be just fine....but, a guy should always be prepared. |
You are correct Bushmaster LIES in their catalog, The bushmaster rep on this site admitted that they only test a few out of every batch Then stamp all of them as tested! Click here to read about it For all you guys that want to keep a spare bolt around in case your bolt fails remember that when a bolt fails the rifle usually blows up (Sometimes with injury to the shooter) & Your spare bolt will not help you.. |
| IIRC, the LMT "enhanced" bolts have a dual-spring extractor-two springs, side-by-side under the tail of a special extractor. It's supposed to make extraction more positive by giving the extractor more power. To me, it is indeed "an answer in search of a question," as a good spring and/or a rubber ring under a standard extractor seems to work so well that anything else is unnecessary. |
I agree, PLus a few Bad reports on the Enhanced bolts performance have been posted here. |
| Not to hijack your thread, but with LMT's enhanced extractor, does it throw the brass further if it offers more powerful extraction? One of my RRAs tosses the cases about 6 feet already, and the other RRA throws them further, but a little erraticly. I wouldn't want to be throwing cases 12 feet or something. That would piss off the folks at the other stations. MJD |

I would like to read about it but the arcive is restricted to team members only, can you post the highlights ? And being fairly new to AR's how often do bolts fail causing this damage and potential injury ? |
Its too long to copy & Paste, Its 5 pages long, If I had to sum it up it says Bushmaster does not MP test all their Bolts/Carriers/Barrels, It only checks a couple out of every batch. But it still stamps all like they were tested! Bolts fail too often for me to trust a bolt that has not been shot peened, Magnetic particle tested & Proof tested. I Mostly use COLT bolts & Carriers (They are also the most numerous available due to their military use), The few I have that are not COLT are the Chrome plated Young Mfg.( I have heard that Smith & Les Baer are also top notch products). |
For the past few months Bushmaster has been working on the implementation of a new technology that we feel will replace magnetic particle inspection. Although we have utilized magnetic particle inspection on a sampling basis in the past we feel that this new method of inspection will allow us to inspect all our critical parts without the requirement for disassembly. There you go. That's a quote from the Bushmaster rep. Note "sampling basis". |
But I am looking for a brand new bolt to mate with my new barrel. I have some spare bolts here, but they've all been used and I would like to do it the absolute right way with this rifle since it'll be my SHTF gun. |
I don’t necessarily disagree with your recommendation, but I think the same goes for FN bolts (bolts both made by FN and made for FN by subcontractor). I don’t know if they still have them, but I picked up a couple from Fulton Armory a few months back. I agree tho, you can’t go wrong with the Colt bolt. |
Already done on page 1 - www.specializedarmament.com |

done already hit the red letters
Damn I gotta learn to type faster I agree with the price, I'd never do it but they have it and you want it NOW, that you pay extra for 
|
There's only one place that sells AR15 bolts (at 250% of normal price), other than that I just have to wait for them to pop up on the EE?

I ordered a couple of bolts from Fulton about 2 months ago after reading a thread that one of their bolt manufacturers is an FN sub called Advanced Armament (the A on the bolt). According to Advanced Armament's web site they claim to be a .gov supplier that does MP all their bolt groups, and I actually got a bolt marked AMP from Fulton. I called Fulton and was told that they had some that were marked and some that were not so I specifically requested the A marked bolts. I had heard that FN's subs weren't supposed to sell to civilians, but rationalized that some subs may be supplementing their sales as the .gov is talking about phasing out the M16. Needing a price break at the time I took the chance that I was getting a true story from the string, Fulton, and AA's site |
In my case I didn't ask for a specific maker and Fulton didn't make a claim that it was FN, they just said it was made by a USGI contractor and I bought a couple. What I got were two bolts marked 'MPF', which according to 'Black Rifle II' is supposed to denote an FN bolt made by subcontractor (the underscore 'F' as opposed to just 'F'). Like you I'm assuming everything is as it seems. I should add btw, they are very nice bolts. They are well finished, very crisp edges, a nice quality machined part. The two M16A1 uppers I got from CDNN shoot like a champ with them. |
