Description

Description

Precision CNC machined from solid billet 7075-T6 aluminum, the SP223 Billet Lower is the first step to building the best AR15 possible. Mil-Spec is just a starting point for Seekins Precision. Specifically designed for serious tactical shooters, the SP223 has features not found on standard AR lower receivers that significantly improve handling and performance. The Seekins Precision Enhanced Bolt Catch comes standard on the SP223. Shooters can easily drop the bolt from either side with our ambi-bolt release feature. Custom screw in dowel pins are used to secure these components, eliminating the use of roll pins, hammers, and pin punches for installation.

An oversized winter trigger guard allows the use of gloves while maintaining precise trigger control, and the trigger reset adjustment screw allows fire control tuning for optimum performance.The quick access mag release and beveled mag well assist with rapid, positive magazine changes and works with most all magazines including Magpul P-Mags and Surefire high capacity magazines.

To assist with exact, no hassle assembly, the rear take down detent has also been relocated under the grip. All of the features and superior design combine to make the SP 223 lower receiver a significant upgrade over common mil-spec lowers.

Started out building off a cheaper lower and ended up like most of us do with a lot of really nice parts in and standard forged lower.wanted to take my Rifle to the next Level and this lower was the perfect choice everything assembled very easy, i love ambi bolt release and all the other built in features. Will be buying more for builds in the future. Works perfect with my ssa-e trigger and ubr

I chose THIS stripped lower for my lefty AR build because of the full ambi design. I expected high quality based on extensive research and this lower not disappoint.

This lower is ridiculous. quality engineering, design, and finish at a better price than OTHER comparable high end, quality lowers (FOP, Spike's, etc).

Rock on Seekins!

Excellent fit and finish, some Magpul mags don't fit

This is a top notch lower receiver - the fit and finish are the best I've ever seen. The Enhanced Bolt Catch is awesome - I would not use another lower without it!
Only issue is the Magpul D60 drum magazine DOES NOT FIT in this lower. I shoot open in 3 Gun and the drum is a must. I moved this lower to another gun and used Seekins SBA15 lower for my 3 gun rifle instead. Both are top notch billet lower receivers!

Still the best lower ive ever built on, wont use any other lowers

A long time ago i bought one of these SP223 custom ambi lowers to do a high end side charge AR/M4 rifle build, after researching and looking at dozens of different lowers and all were about the same with only a couple that stood out from the crowd. I had it narrowed down to the SP223 and one other custom lower and it was an easy choice to go with the Seekins lower because of all the advanced and ambi features which are important for me being a left handed shooter, so i went with only the highest end and best known products available for this build. I put over $2700.00 into the rifle without scopes and lasers and lights, just the rifle build was $2700.00 and the Seekins lower was the heart of it all and it is still my favorite rifle to shoot.
These lowers have so many cool and convenient options and features that it stands far above the rest so if you want your next build to be the best rifle youll ever own, go with a Seekins lower and Seekins build parts. And if thats not enough by itself then you should know that on The Walking Dead Series, Sasha uses a Seekins Precision AR/M4 so thats a bonus knowing that one of Rick's best shooters uses a Seekins Precision rifle in the 5th and 6th seasons. Walking Dead Fans should order your receivers quick and make your own replica of Sashas rifle.

Top tier quality

Seekins precision products began to stand out with this sp223 lower and subsequent upper receivers with their corresponding handguards. It took me 2 years to pony up the cash for this lower but I have not regretted it since. It is my stand-alone best build. The billet design is beyond top notch and there is still very few options out there that can compete with the overall look and quality. The only gripe I have is the OVER-ENGINEERING of some of the small allen wrench screws that are needed to be removed to complete the building process. I'm assuming that some of these differ from standard lowers because of the design. It's worth the hassle but there needs to be more helpful and specific information and links on this website to assist builders. At times, I felt I needed a third hand with my .50 allen to get the job done. In the end, it was worth it and I would buy Seekins products any time I have the desire (and cash) to build another.

This lower is what judge all other lowers by. After owning this one you will not be satisfy with other brands. Builds easy & looks good. Seekins did good job.

The Only Lower For All Of My Future Builds

This is a fantastic lower that I plan to use to replace many of my existing forged lowers with as well as any new builds that I plan to do in the future.

If you are like me and hate dealing with all of the pins that have to be hammered in with a punch you are going to love the Seekins lower!

Also I have had zero fitment issues with other parts such as drop in triggers (POF units) compared to my forged lowers.

Add in the beautiful contours and the drilled our integrated trigger guard (one less item to buy) and the overall clean lines, this is a beautiful piece that I want on all of my AR's.

I love this damn thing SOOOO Much

I had been wanting to do a high end custom build for a while now, but where to start? I knew i wanted a siDe charge upper receiver and a high end lower receiver, but there are so many receivers on the market its so hard to wade through the massive amount, but narrowing it down to just a couple wasnt too hard. I decided to give the sp223 a shot since i got a good deal on it and i liked the logo model a lot and the list of features on it over the others on the market made the final decision fairly easy, ao i picked one up and ordered My side charge upper and a good amount of the other parts needed to complete the build. Now that the rifle is built and looks awesome with the Seekins SP223 lower and it really makes it stand out when paired with my side charge upper. The only problem i encountered was that the very pretty factory installed custom bolt catch would not allow the upper and lowers to mate together because it was a bit too wide but i planned on going with a Phase 5 extended low profile bolt release and when i got it in i was hoping it would fix the mating of the receivers together problem, which it did and now i get so many compliments and wow look from everyone who sees the rifle and i know its due to the lower receiver. Yes everything else looks great too but the sp223 is way nicer then all the others i looked at and researched before buying this one so if your doing a high end custom build then this receiver is the one you need and it makes installing some of the detents and springs way easier theN on standard mil spec lowers. I plan on picking up a second one just to have if i build another AR.. God i love this thing and price while a bit higher then most others is well worth it when comparing quality and features
