Tactical Machining Lower project

Well as noted from an earlier post, I've been in the market for a lower, you guys gave me some great advice and what to look for in a receiver. But today i ran across a sale at a gunshop near my work, the one were my friend got his ruger american, and they had a sale from black Friday they were still honoring. the brand as stated is tactical machining 5.56 AR 15 lower its price was 95$, and its forged aluminum. it felt nice and strong in my hands and im looking forward to building this project with the help of my father.

I did do some quick research and its supposedly a good receiver for the money, the tensioner system is built into the receiver (i just need said parts for it) also needed the "bullet button" as im in CA (cry), so im thinking i need a lower parts kit , an upper + barrel (18-20) long , and a stock top start the project off.(recommendations are welcome!)

here is a review from last year on the product via major pandemic
link

here are the manufacturer images of said receiver

so far im unsure what setup i should go with. im thinking of going with a side assit for the hammer, in case of dirt build up. (now im anal about cleaning my guns so i doubt that, but i think its a good idea to have one)


so first a lower kit is needed. just basics that is reliable(any recommendations)?

also looking at complete upper , and a 18" or 20 " barrel in 5.56

i need a stock that i can adjust the check rest on

Tactical Machining is a good company. They are local to me and I've heard good things about them, although I've never bought their parts for any of my AR15 builds.

For barrels, there are plenty of choices. It will really be up to you how long a barrel you want/need depending on your budget and use for the rifle.

I would recommend a Spikes Tactical barrel in 16" from AimSurplus website:

http://www.aimsurplus.com/catalog.as...3&name=Barrels

Although the top of the line ST-FN 16" barrel ($269) is sold out, it is an excellent barrel with a 20,000rd service life!

They do have a 14.5" barrel in stock for $199 that has a midlength gas port, but you would have to permanently attach a muzzle device to it to make it 16" legal length (non-NFA).

There are plenty of other barrel choices from Noveske, Daniel Defense, and FN, etc. Just look online and see which one you want to go with that is within your budget.

well ive always like the longer barrel length design on the AR types. i was thinking the 18" or 20" would be for the best. as i am typically a 100-300yard shooter i usually spec my rifles to be in that range. the longer barrel would help with accurcay at that range.

im glad you posted those brand names, as im new to ar's im unsure whats top line vs bottom of the barrel parts. i usually go over the top and get quality forged parts for the reliability stand point

ive had a few other members offering to help, and sell products to me at good prices, (i really appreciate the offers guys!)

also wanted to thank those on my AR question thread, you guys are great, very insightful, and have lots of knowledge on this subject (which i lack)

mainly putting my projects on hold for a bit.

Also had a few businesses that ive been talking too offer some discounted products, spikes tactical was well represented. got an offer on a multical upper T6 forged with a lightweight BCG NIB for 200$ together. not sure if thats good, im curious about this light weight bolt, as i do know that the lighter the bolt, means the faster the cycle rate will be, but im worried it would create bolt jump. i have not found anything so far on this lightweight BCG, besides a few reviews

talking to rock river arms on getting a barrel in 20" stainless , chrome lined.
Also will get an adjustable gas block as i dont think ill shoot constant ammo, will vary on my budget, so thats something to think about. need a barrel nut, and a charge handle. im looking at the ergo delux grip with and plate

well difficulties finding a barrel, most are backordered, so rather than wait for long period of time( delaying my project) i got in contact with spikes and made a deal for an upper (m4 style multi caliber), and a buffer tube kit (no stock)

it was 100$ for the upper and 74.95 for the buffer tube kit(no stock)

i thought this was a good deal as ive gathered that spikes has a good rep for good performance and parts. ill get a magpul accessories (as I like their quality)

still trying to knock down the price on a BCG, they are stubborn on that, but im hopeful

Mic the boss where the gas port is, the standard is .750" but there are others. I Just built a carbine with a fluted Red X 16" SS barrel and so far it is a neat rifle and very accurate.

BCG?

Did you get a BCG yet?

There are countless brands to choose from. Just advising you to pick one that is well known and properly "Milspec". BCM or Spikes come to mind. I bought a Spikes M16 BCG for $140 shipped 2 weeks ago.

i was looking at spikes Bcg lightweight, till a buddy recommended another bcg that would suit me better

currently just saving the funds for it, but im planning to get one from leitner wise, talked to the owner of the company and hes a nice guy, its on sale for 190 $ but im just holding off. i like design because instead of a cauter pin systems it has an actual solid pin to hold the firing pin in place, it also does not drop the pin when its pushed out making it better for on the fly cleaning of the firearm IMO. i like the nitrite system due to it being a chemical change rather than a plating. and these are guaranteed life time warranty , also the bcg is in 5.56.

While I don't doubt that these folks offer quality products, I don't see any reason at all to prefer a solid pin over a cotter pin to retain the firing pin.

well its looks like the design of the original m16 bolt , with having a solid pin system. but truthfully i like that it plugs that hole up, so less grit/dirt and such get in on that opening. not sure of practicality other than its good for quick take down and wont lose the pin....

Dirt and grime do not get into that hole for the firing pin retaining pin. Its a non-issue at all, but if you want that BCG, it looks good (although kinda pricey).

On a side note, if you are posting pics, try posting the pic directly instead of a link. Makes it easier to follow your thread and not have to keep clicking at each link. (just a suggestion though).

Good luck with the rest of the build. You got some nice parts on there so far. Keep it up.

Just to get you more motivated to finish it, here is my current Spikes AR build. Waiting on the barrel and I should be finished



bottom rifle is Smith and Wesson M&P15-22

You can post your pics like I did above so it is easier to see your progress
